Campylobacter jejuni/coli AB

Candida IgA, IgM, IgG Blood Test

This candida test is used to screen for antibodies the body develops in response to Systemic Candidiasis or Candida. Candida is another name for yeast, a fungus which is normally found in small amounts in the body. The immune system normally keeps Candida under control but in cases where a person is sick or taking antibiotics the yeast may spread, becoming a potentially dangerous infection. This candida test looks for 3 antibody types including Iga, IgM and IgG.

Cardiovascular & Stroke Screenings

Life Line Screening offers a suite of Cardiovascular & Stroke Screenings aimed at detecting potential risk factors and underlying conditions that could lead to serious health issues in the future. These screenings primarily focus on identifying signs of carotid artery disease, atrial fibrillation, and peripheral arterial disease, as well as assessing the risk of stroke and abdominal aortic aneurysm. Utilizing non-invasive technologies such as ultrasound and electrocardiograms (EKGs), Life Line Screening provides these services in community-based settings like churches, community centers, and offices. The goal is to facilitate early detection of cardiovascular conditions, which can be crucial for timely intervention and management, potentially preventing the progression of these conditions into more severe complications. This approach is particularly targeted towards older adults and those with risk factors for cardiovascular disease, aiming to reduce future health risks and medical costs through preventive care.

Catecholamine blood test

What are Catecholamines? Catecholamines are a group of similar hormones released into the bloodstream in response to physical or emotional stress. Catecholamine testing measures the amounts of these hormones in the urine and/or blood. Urine testing is recommended over blood testing. Functions of Catecholamines: Catecholamines are released into the bloodstream in response to physical and emotional stress to: help transmit nerve impulses in the brain, increase glucose and fatty acid release for energy, dilate bronchioles (decreasing resistance in the respiratory airway and increasing airflow to the lungs), dilate the pupils. The above functions only increase during and shortly after a stressful situation and the broken down catecholamines are then eliminated from the body through the urine.

Catecholamines, Fractionated, Random Urine

Catecholamines, Fractionated, Random Urine is a test that measures the levels of certain hormones called catecholamines in a random urine sample. Catecholamines are a group of hormones and neurotransmitters that include substances like epinephrine (adrenaline), norepinephrine, and dopamine. These chemicals play essential roles in the body's "fight or flight" response, regulating blood pressure, heart rate, and other physiological responses to stress. The test is typically used to diagnose and monitor certain medical conditions, such as: Pheochromocytoma: This is a rare tumor that can develop in the adrenal glands (located on top of the kidneys) and can produce excessive amounts of catecholamines. Elevated levels of catecholamines in urine can be a sign of pheochromocytoma. Paraganglioma: Similar to pheochromocytoma, paragangliomas are rare tumors that can develop in other parts of the body and also produce excess catecholamines. Neuroblastoma: This is a type of cancer that commonly occurs in children and can also produce high levels of catecholamines.

CDSA Level 1 Comprehensive Digestive Stool Analysis

CDSA Level 1 – Comprehensive Digestive Stool Analysis (NutriPATH) NutriPATH offers a broad range of gastrointestinal test panels designed to give healthcare practitioners the flexibility to choose the most appropriate analyses for each patient’s needs. The CDSA Level 1 test provides a detailed assessment of the gut’s microbiological environment.

It also supports clinical decision-making when evaluating the necessity of more invasive procedures such as colonoscopy.

Celiac & Gluten Sensitivity; blood spot

Celiac disease is a common but often underdiagnosed autoimmune condition that affects the small intestine and impairs nutrient absorption. Over time, untreated celiac disease can contribute to a wide range of health issues, including digestive symptoms, nutrient deficiencies, fatigue, and even other autoimmune disorders. Many individuals remain asymptomatic for years, making early detection especially important. This panel evaluates key antibodies associated with both celiac disease and non-celiac gluten sensitivity (NCGS). These markers reflect how the immune system responds to gluten exposure. For accurate results, it is essential that testing is performed while consuming a gluten-containing diet. The primary antibodies measured include: Tissue Transglutaminase (tTG) antibodies Deamidated Gliadin Peptide (DGP) antibodies Testing includes both IgA and IgG antibodies. While IgA is typically used for celiac screening, individuals with celiac disease have a higher likelihood of selective IgA deficiency, which can lead to false-negative results if IgG markers are not assessed.

Celiac Comprehensive Panel

Celiac Comprehensive Panel A Comprehensive Celiac Panel is a set of blood tests used to screen for and help diagnose celiac disease—an autoimmune disorder triggered by gluten, the protein found in wheat, barley, and rye. In people with celiac disease, the immune system mistakenly attacks the lining of the small intestine. Over time, this can cause intestinal damage, poor nutrient absorption, digestive upset, anemia, fatigue, and other health problems. What this panel measures This panel combines several antibody and immune markers to improve accuracy and reduce false negatives: Tissue Transglutaminase IgA (tTG-IgA): The most common and sensitive screening test for celiac disease. Elevated levels strongly suggest an autoimmune response to gluten. Tissue Transglutaminase IgG (tTG-IgG): Useful for individuals with IgA deficiency, a condition that can otherwise mask celiac disease. Deamidated Gliadin Peptide (DGP) IgA and IgG: Detect immune responses against gluten-derived proteins. Helpful in children and when tTG results are inconclusive.

Cerebrospinal Fluid (CSF) Analysis

A CSF analysis, also known as spinal fluid analysis or CSF testing, comprises a set of tests that utilize a sample of cerebrospinal fluid to diagnose various conditions affecting the brain, spinal cord, and the central nervous system. These tests are valuable for identifying neurological diseases, infections, and other health issues that may impact CNS function. CSF plays a crucial role as a protective cushion for the brain and spinal cord, guarding them against sudden impacts and injuries. Additionally, it serves as a waste disposal system, aiding in the removal of metabolic waste products from the brain. This function is essential for maintaining the optimal functioning of the central nervous system.

Chemistry Tests

A Chemistry Tests panel, often referred to as a Chemistry Panel or Chem Panel, is a comprehensive set of tests used to evaluate the general health status of an individual and diagnose a wide range of conditions. This panel typically measures various substances in the blood, including electrolytes (like sodium, potassium, and chloride), enzymes, fats, proteins, glucose, and metabolic waste products. The specific tests included can vary, but common ones are the Comprehensive Metabolic Panel (CMP) and Basic Metabolic Panel (BMP), which assess kidney function, liver function, blood sugar levels, and acid/base balance, among other vital functions. The results can help in detecting abnormalities that may indicate diseases such as diabetes, kidney disease, liver disease, and hypertension. It's also used to monitor the effectiveness of medications and the impact of chronic diseases on the body.

Chlamydia/Chlamydophila Ab PNL 3 (IgG, IgA, IgM)

The Chlamydia/Chlamydophila Antibody Panel 3 (IgG, IgA, IgM) is a comprehensive serological test used to detect antibodies against Chlamydia and Chlamydophila species in a patient's blood. This panel tests for three types of antibodies: Immunoglobulin G (IgG), Immunoglobulin A (IgA), and Immunoglobulin M (IgM), each providing different information about the timing and stage of the infection. IgG antibodies are usually indicative of a past infection or a later stage of an ongoing infection, as they develop over a longer period and can persist for years. IgA antibodies are often associated with mucosal infections and can indicate a more recent or ongoing infection, especially in the respiratory or genital tracts. IgM antibodies are the first to appear in response to an infection and suggest a recent or acute infection. The Chlamydia/Chlamydophila Ab PNL 3 is particularly useful in diagnosing infections like Chlamydia pneumoniae, which can cause respiratory illnesses, and Chlamydia trachomatis, known for causing sexually transmitted infections and trachoma.

A comprehensive metabolic panel (CMP) measures 14 markers of blood sugar, kidney function, liver health, electrolytes and protein. This page explains what your results mean. Key Takeaways A Comprehensive Metabolic Panel (CMP) measures 14 biomarkers that evaluate blood sugar, kidney function, liver health, electrolytes, and protein levels. Typical adult ranges include glucose ~70–99 mg/dL, creatinine ~0.6–1.3 mg/dL, sodium 135–145 mmol/L, and ALT ~7–56 U/L, although ranges vary slightly by laboratory. High CMP values may indicate dehydration, kidney disease, liver dysfunction, diabetes, or electrolyte imbalance. Low values may occur with malnutrition, overhydration, medication effects, or hormonal disorders. Doctors interpret patterns across the entire panel, not individual numbers in isolation. What Is a CMP Blood Test? A Comprehensive Metabolic Panel (CMP) is one of the most commonly ordered blood tests. It evaluates multiple aspects of metabolic and organ health by measuring markers related to blood sugar, kidney function, liver health, electrolytes, and protein balance.

Comprehensive Stool Analysis / Parasitology

The Comprehensive Stool Analysis detects the presence of pathogenic microorganisms such as yeast, parasites, and bacteria that contribute to chronic illness and neurological dysfunction. It provides helpful information about prescription and natural products effective against specific strains detected in the sample. The test also evaluates beneficial bacteria levels, intestinal immune function, overall intestinal health, and inflammation markers. Many chronic disorders come from digestive problems and inadequate nutrient absorption. Proper gastrointestinal function is needed to eliminate toxic substances, pathogenic microbes, and undigested food particles from the body to prevent health problems. Nutrients require a specific internal environment to be properly digested and transported throughout the body. Abnormal intestinal microorganisms in the GI tract are widely known to cause disease. Research shows a relationship between the GI tract and the neurological, hepatic, and immune systems.

Coronavirus Disease 2019 or COVID-19 (formally known as 2019-nCoV) is the name for the respiratory syndrome caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Coronary calcium scan

Other names for this test are: Coronary artery calcium (CAC) test, Coronary calcium CT scan, Heart CT calcium scan. A coronary calcium scan, also known as a coronary artery calcium (CAC) scan, is a specialized type of computed tomography (CT) scan that measures the amount of calcium in the walls of the coronary arteries, which supply blood to the heart muscle. This non-invasive imaging test is used to evaluate the risk of coronary artery disease (CAD), a leading cause of heart attacks. Calcium in the coronary arteries is an early sign of CAD, as it's a component of plaque that can narrow or block these arteries, leading to heart disease. The scan produces a calcium score, which reflects the extent of calcification in the coronary arteries. A score of zero indicates no detectable plaque and a low risk of a coronary event in the near future, while a higher score suggests a greater risk. This score helps in stratifying patients into different risk categories for heart disease and can guide physicians in making decisions about preventive measures and treatment strategies.

Cortisol Awakening Response (CAR)

The Cortisol Awakening Response (CAR) test is a non-invasive saliva test that serves as a reliable marker of stress response and a critical tool for revealing adrenal imbalances. Lifestyle, physical and psychological stresses put constant demands on the adrenal glands. If they become depleted adrenal fatigue or insufficiency may be experienced. The Cortisol Awakening Response (CAR) test is a unique assessment measuring the predictable rise and fall in cortisol within the first hour of awakening. The test is essential in evaluating the overall function of the HPA axis. In this particular test we measure cortisol immediately on rising, 30 minutes post waking, 60 minutes post waking, 12:00 (noon), 4:00pm and 8:00pm. The CAR test allows your physician to determine how healthy your HPA axis is which useful in assessing the HPA-axis. The CAR test is an appropriate tool in practice for most of your patients as it provides an easy assessment of their ability to deal with stressors and is also reflective of how well they have dealt with stressors in the past.

Cortisol Awakening Response + DHEA (Saliva)

Cortisol Awakening Response (CAR): - CAR represents the momentum of rising cortisol levels that begins several hours prior to awakening and an additional transient increase. - CAR reflects a person’s ability to cope with anticipated challenges and the perceptions of control around chronic stress. Elevated levels of CAR: - Elevated levels may be due to stress, exercise, alcohol, and specific lifestyle stressors. - Elevated evening salivary cortisol is linked to insomnia. - High evening cortisol levels are also associated with various diseases such as diabetes, cardiovascular disease, hormonally driven cancers, and osteoporosis. DHEA: DHEA levels peak at around age 25, then decline steadily through the following decades. DHEA can be converted downstream in the steroidogenic pathway to create androgens and estrogens. It has antioxidant and anti-inflammatory properties and can be protective against corticosterone’s neurotoxic effects.

CORTISOL, LC/MS, SALIVA, 4 SAMPLES

Salivary cortisol level, particularly late-night salivary cortisol (LNSC) level, is useful in screening for endogenous Cushing syndrome. Two or more positive results of LNSC tests may be used to confirm Cushing syndrome. LNSC measurement may also be used to monitor for recurrence of Cushing disease. Normally, the secretion of cortisol has a circadian rhythm. Patients with Cushing syndrome often lose the late-night circadian nadir (= low point). Therefore, an elevated LNSC level may provide initial evidence for Cushing syndrome. Two or more positive results of LNSC tests may establish the diagnosis of Cushing syndrome if non-neoplastic hypercortisolism (pseudo-Cushing syndrome) is excluded. Because saliva is convenient to collect, LNSC testing is especially useful for individuals who need to provide multiple specimens over time for the evaluation of cyclic Cushing syndrome. Annual LNSC testing is recommended to monitor for the recurrence of Cushing disease after pituitary surgery.

Coxsackie A IgG Antibody

The Coxsackie Antibody, IgG test is used to detect antibodies against the Coxsackie virus in the blood. This condition is most common in children under the age of five, and it can cause Hand, Foot, and Mouth disease. Coxsackieviruses are part of the enterovirus family of viruses (which also includes polioviruses and hepatitis A virus) that can live in the human digestive tract. In most cases, coxsackievirus infections cause mild flu-like symptoms and go away without treatment. But in some cases, they can lead to more serious infections. The viruses can spread from person to person, usually on unwashed hands and surfaces contaminated by feces, where they can live for several days.

Coxsackie A IgM Antibody

The Coxsackie A gM Antibody panel is a diagnostic tool used to detect the presence of antibodies against the Coxsackie A virus, a significant member of the Enterovirus family. This panel differentiates between IgG and IgM antibodies, providing crucial insights into the timing and stage of the infection. IgM antibodies typically indicate a recent or ongoing infection, as they are the first antibodies produced by the immune system in response to an infection. In contrast, IgG antibodies develop later and can indicate a past infection or a more mature immune response. This test is especially important in diagnosing conditions caused by Coxsackie A virus, such as hand, foot, and mouth disease, herpangina, and various other systemic illnesses. Accurate identification through this antibody panel aids in appropriate clinical management and understanding of the patient's immune status regarding Coxsackie A virus exposure.

Coxsackie B Virus Antibodies

This test is used to aid in diagnosing Coxsackie virus infection. Coxsackie B viruses cause a wide variety of illnesses, including pleurodynia (Bornholm disease), meningitis, rash, pulmonary infection and a generalized systemic infection. The Coxsackie B Virus Antibodies panel is a critical diagnostic tool used for detecting antibodies against the Coxsackie B virus, a key pathogen within the Enterovirus genus. This panel specifically tests for the presence of antibodies to several serotypes of the Coxsackie B virus, typically Coxsackie B1 through B6. The presence of these antibodies in a patient's blood can indicate either a current or past infection. Coxsackie B viruses are known to cause a variety of illnesses, ranging from mild syndromes like fever, pleurodynia, and herpangina, to more severe conditions such as myocarditis, pericarditis, and meningitis. In some cases, they are also implicated in the development of chronic diseases, including dilated cardiomyopathy and diabetes.

Coxsackie IgG-/IgA-antibodies

Creatinine (Urine) - DUTCH

In this section of the DUTCH test, you’ll see your creatinine values from all four urine samples collected throughout the day. Creatinine is measured for one important reason: to correct hormone results for urine dilution. Why Creatinine Matters in Urine Hormone Testing The concentration of hormones in urine can vary depending on how diluted your sample is. If you are well-hydrated, your urine is more diluted, and hormone concentrations appear lower. If you are dehydrated, your urine is more concentrated, and hormone levels may appear higher. Creatinine correction adjusts for these differences. Because creatinine is excreted at a relatively steady, predictable rate in healthy individuals, it serves as a reliable reference point to “normalize” your results, regardless of hydration. Creatinine Correction and Accuracy The DUTCH test uses creatinine correction to make its spot urine samples comparable to the gold standard: a 24-hour urine collection. A 24-hour urine test captures hormone excretion over an entire day but can be difficult for patients to complete correctly.

Cytokine assay panel for immune profile

Cytokines are a large group of secreted proteins with diverse structures and functions, which regulate and coordinate many cells activities of innate and adaptive immune systems. Therefore, these molecules are involved in multiple processes: acute inflammations such as infectious or post-vaccinal conditions, chronic inflammations such as autoimmune diseases, chronic infections or tumors.
