Total Cytotoxic NK cells (CD16+)
Optimal Result:
30 - 200 cells/uL.
Total Cytotoxic NK (Natural Killer) cells, identified by the CD16+ marker, represent a crucial component in the innate immune system, playing a significant role in the body's first line of defense against tumors and virally infected cells.
NK cells, characterized by their expression of the CD16 surface marker, are involved in the direct killing of target cells without the need for prior sensitization, distinguishing them from other lymphocytes that require antigen presentation. They are pivotal in controlling early responses to infection and malignancy through the release of cytolytic granules that induce apoptosis in target cells.
Moreover, CD16+ NK cells can mediate antibody-dependent cellular cytotoxicity (ADCC), a mechanism by which cells coated with antibodies are recognized and destroyed, further emphasizing their role in immune surveillance and therapy. The assessment of Total Cytotoxic NK cells in the Lymphocyte MAP panel provides critical data, aiding in the diagnosis and monitoring of immune disorders, evaluating the risk of autoimmune diseases, and tailoring personalized immunotherapy treatments. This analytical capability underscores the importance of understanding NK cell dynamics in clinical practice, enhancing the precision of immune health assessments and the development of targeted therapeutic strategies.
Lab Results Explained and Tracked
What does it mean if your Total Cytotoxic NK cells (CD16+) result is too high?
Elevated levels of Total Cytotoxic NK cells (CD16+) can indicate an active immune response against infections, tumors, or other pathological conditions, reflecting the body's attempt to combat these challenges. Such an increase often suggests an ongoing battle against viral infections or the presence of malignant cells, as NK cells play a crucial role in identifying and destroying compromised cells without prior sensitization. Additionally, persistently high levels may signal an underlying autoimmune disorder or a chronic inflammatory state, where the immune system is in a heightened state of alert, potentially targeting the body's own tissues mistakenly. The interpretation of these elevated levels, particularly within the context of the Lymphocyte MAP panel from Cyrex Laboratories, requires a comprehensive assessment by healthcare professionals, taking into account the patient's clinical history, symptoms, and other diagnostic findings to understand the implications fully and tailor appropriate therapeutic interventions.

What Healthmatters Members Are Saying
I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
