% CD3 (Mature T Cells)

Optimal Result: 57 - 85 %.

The percentage of CD3+ T cells, often referred to as mature T cells, is a crucial component of the immune system and plays a central role in defending the body against infections and other foreign invaders. These cells are characterized by the presence of the CD3 surface marker, which is involved in T cell receptor signaling. CD3+ T cells can be further divided into two main subsets: CD4+ T cells (helper T cells) and CD8+ T cells (cytotoxic T cells). CD4+ T cells assist in orchestrating immune responses by coordinating various immune cells and directing them to combat specific pathogens. On the other hand, CD8+ T cells are responsible for directly identifying and destroying infected or abnormal cells, such as virus-infected cells and cancer cells. An optimal balance and functionality of these T cell subsets are critical for a healthy immune response.

A decreased percentage of CD3+ T cells can indicate potential issues with the immune system's overall health. Such reductions may result from a variety of factors, including immunodeficiency disorders, viral infections like HIV that target and deplete CD4+ T cells, medications that suppress the immune system, autoimmune disorders where the immune system attacks the body's own cells, bone marrow disorders that affect T cell production, and the natural aging process. Monitoring CD3+ T cell levels is essential in diagnosing and managing various medical conditions, particularly those affecting the immune system. A healthcare provider will typically interpret CD3+ T cell percentages alongside other clinical data to determine the underlying cause and decide on appropriate treatment or intervention if necessary. Ensuring a balanced and functional CD3+ T cell population is crucial for the body's ability to fend off infections and maintain overall health.

What does it mean if your % CD3 (Mature T Cells) result is too high?

The proportion of all immune cells that are T cells. This figure is rarely used for making treatment decisions.

What does it mean if your % CD3 (Mature T Cells) result is too low?

A decreased percentage of CD3+ T cells, which represent mature T cells in the blood, generally indicates a potential issue with the immune system. Mature T cells are a crucial component of the immune system, responsible for recognizing and responding to specific pathogens and abnormal cells. When the percentage of CD3+ T cells is lower than normal, it can be indicative of several underlying conditions or factors, including:

  1. Immunodeficiency Disorders: Certain inherited or acquired immunodeficiency disorders can result in a reduced number of mature T cells, compromising the immune system's ability to fight infections effectively.
  2. Infections: Some viral infections, particularly HIV (Human Immunodeficiency Virus), can lead to a decline in CD3+ T cell levels as the virus specifically targets and destroys these cells.

  3. Medications: Certain medications, such as immunosuppressants used in organ transplant recipients or for autoimmune diseases, can lower T cell counts as a side effect.

  4. Autoimmune Disorders: Autoimmune diseases, which involve the immune system attacking healthy cells, can sometimes lead to alterations in T cell populations.

  5. Bone Marrow Disorders: Conditions affecting the bone marrow, where T cells are produced, can impact T cell levels.

  6. Aging: Normal aging can lead to a decrease in T cell counts, which is a part of the natural aging process.

It's essential to evaluate a decreased percentage of CD3+ T cells in the context of a patient's medical history, symptoms, and other laboratory results. Additional diagnostic tests and consultation with a healthcare provider are typically necessary to determine the underlying cause and appropriate treatment or management if needed.

You can combine all test reports inside your Healthmatters account and keep them in one place. It gives you an excellent overview of all your health data. Once you retest, you can add new results and compare them.

If you are still determining whether Healthmatters support your lab results, the rule is that if you can test it, you can upload it to Healthmatters.

While we work with many popular labs, we welcome reports from lots of other places too.

It's as simple as this: if you can get a test done, you can upload it to Healthmatters and we can interpret results from any lab out there. If laboratories can analyze it, we can interpret it.

If you’re on the hunt for a specific biomarker, contact us and we'll add it to our database. Anything from blood, urine, saliva, or stool can be uploaded, understood, and tracked with your Healthmatters account.

There are two ways to add your test reports to your Healthmatters account. One option is to input the data using the data entry forms. The other method is to utilize our "Data entry service."
