% CD 3 Pos. Lymph.

Blood
Optimal Result: 57.5 - 86.2 %.

The biomarker "% CD 3 Pos. Lymph." in a T + B-Lymphocyte Differential panel from Labcorp refers to the percentage of lymphocytes in the blood that are CD3 positive. CD3 is a protein complex and a T-cell co-receptor that defines T-lymphocytes, which are crucial components of the immune system.

This marker is used to evaluate the immune system's health, particularly in diagnosing and monitoring conditions affecting T-cell function, such as immunodeficiency disorders or certain types of leukemia. The measurement of CD3 positive lymphocytes helps in understanding the proportion of T cells in the overall lymphocyte population, providing insight into the body's adaptive immune response.

What does it mean if your % CD 3 Pos. Lymph. result is too low?

Low values of "% CD 3 Pos. Lymph." in a T + B-Lymphocyte Differential panel indicate a reduced proportion of CD3 positive T-cells in the blood. This can be associated with various clinical conditions, including certain immunodeficiency disorders where the immune system's ability to fight infections is compromised. It can also occur in conditions affecting T-cell production or function, such as HIV/AIDS, chemotherapy, or after organ transplantation. Low CD3 positive lymphocyte counts might signal a weakened immune response and require further investigation and management by healthcare professionals.

What does it mean if your % CD 3 Pos. Lymph. result is too high?

Elevated levels of "% CD 3 Pos. Lymph." in a T + B-Lymphocyte Differential panel typically indicate an increased proportion of CD3 positive T-cells in the blood. This increase can occur in various conditions, including certain autoimmune diseases, where the immune system is overly active and attacks healthy tissues. It might also be seen in lymphoproliferative disorders, where there is an abnormal increase in lymphocytes, or in response to infections, as the body mounts an immune response. As with any lab result, interpreting high CD3 positive lymphocyte counts should be done in the context of the overall clinical picture, and it's important to consult with healthcare professionals for a thorough assessment.
