Fecal Immunochemical Test (FIT) – Stool Occult Blood

The fecal immunochemical test (FIT) checks for hidden blood in stool using antibodies specific to human hemoglobin. This makes it more accurate for detecting bleeding from the colon or rectum than older guaiac-based stool tests, and unlike those tests, FIT does not require dietary restrictions.

Blood in stool can result from polyps, colorectal cancer, hemorrhoids, inflammation, or other lower GI conditions. Detecting blood early is important, since finding and removing polyps may help prevent colorectal cancer. For people at average risk, FIT is often recommended once a year beginning at age 45.

How to collect: Use the provided kit exactly as instructed—usually swiping a brush or applicator across the stool surface, sealing it in the collection tube, and returning it promptly. Try to avoid collecting during menstruation or with heavy hemorrhoid bleeding.

Interpreting results:

• Negative: No blood found. This is reassuring, but regular screening is still needed, since some problems bleed intermittently.

• Positive: Blood was detected. This does not necessarily mean cancer but usually leads to a follow-up colonoscopy to find the cause.

• Invalid: The sample could not be tested correctly and should be repeated.

While a positive result may be caused by polyps, hemorrhoids, fissures, or inflammation, it should always be followed up. A negative test lowers the chance of bleeding from the colon, but continued annual testing is important.

Ochratoxin is a nephrotoxic, immunotoxic, and carcinogenic mycotoxin. This chemical is produced by molds in the Aspergillus and Penicillium families.

Exposure:

Exposure is done primarily through water damaged buildings. Minimal exposure can occur through contaminated foods such as cereals, grape juices, dairy, spices, wine, dried vine fruit, and coffee. Exposure to Ochratoxin can also come from inhalation exposure in water-damaged buildings.

Ochratoxin can cause immune suppression, lung disease, urinary tract tumors, and is nephrotoxic (kidneys), hepatotoxic (liver), genotoxic (genes), and carcinogenic (causes cancer). This is due to its ability to form DNA adducts and inhibit protein synthesis. Ochratoxin can potentiate the effects of IL-1 Bon IL-8 secretion with a range of 35% to 138% increase and augments the transepithelial passage of commensal bacteria with a 12- to 1522-fold increase. Studies have shown it causes leaky gut syndrome and changes the nutrients that are absorbed from foods.

A toxin produced by different Aspergillus and Penicillium species — is one of the most-abundant food-contaminating mycotoxins. It is also a frequent contaminant of water-damaged houses and of heating ducts. Exposure can also come from inhalation in water-damaged buildings.

Ochratoxin A is a mycotoxin produced by some Aspergillus and Penicillium species and found in contaminated foods and other environments. This urine test reports the amount detected relative to creatinine. Mosaic flags results above its laboratory-specific reference interval, but that boundary is not a toxicity or disease threshold. A high result does not diagnose mold illness, prove that a building was the source, show that OTA caused your symptoms, or determine what treatment you need. Urinary mycotoxin testing has limited clinical validation, and healthy people can have detectable OTA. Read the result with your clinician in the context of the laboratory method, diet, documented environmental conditions, symptoms, and other possible explanations.

Ochratoxin A (OTA), a renal toxin, is produced majorly by Aspergillus and Penicillium fungal species. Ochratoxin A has been found in barley, oats, rye, wheat, coffee beans, and other plant products, with barley having a particularly high likelihood of contamination. It is also frequently found in pork intended for human consumption.

The bacteria are found in the human gut where they are considered “commensal”, which means “eating from the same dish”. They exist in the human body without either helping or hindering us.

OH-Butyrylcarnitine (C4OH) is a hydroxy-acylcarnitine involved in the breakdown of short-chain fatty acids and certain amino acids. It reflects how efficiently mitochondria process these fuels to generate energy. Because C4OH is sensitive to shifts in fatty acid oxidation and mitochondrial demand, its levels provide useful insight into metabolic flexibility and overall cellular energy function.
