The CD57 blood test is generally another piece of the puzzle of diagnosing chronic Lyme disease. Boosting IL-15 activity might promote tumor-reactive CD8+ T-cell functional maturation while preserving their proliferative activity. This test was performed in a CLIA certified laboratory and is intended for clinical purposes. We've put industry-leading security standards in place to help protect against the loss, misuse, or alteration of the information under our control. The utility of this test is controversial. T-cells, on the other side,belong to the adaptive immune system. Re-use permitted under CC BY-NC. It started with a rash from my groin area on 1 thigh similar to ring worm and about. These cells are predominantly CD8 positive, with CD4 negative or minimally expressed. This study aimed to explore the immune response in EBV-related diseases and the correlation between immune cells and adenosine deaminase (ADA) levels.

CD57+ T cells expressed high levels of programmed cell death-1 (PD-1) in all tested compartments and were predominantly CD8+ T cells. The data is stored in a computer and reported via a histogram or dot plot. The CD57 blood test is used by Lyme literate doctors to screen for the possibility of a chronic infection so that someone may be appropriately treated. Indicate date and time of venipuncture on the tube(s) and on the test request form. Borrelia are believed to be capable of reducing the total amount of CD57 natural killer cells in the human body. Specifically, flow cytometry is used in research for a number of purposes, including: Flow cytometry may be used to characterize and count types of white blood cells in the evaluation of infectious diseases, autoimmune disorders or immunodeficiencies. CAS Anything below 60 is generally considered an indication of chronic Lyme disease. Their absolute values and patient history/clinical context are key to their relevance or utility. Because a high frequency of CD8+CD57+ T cells is associated with short-term cardiovascular mortality in acute MI patients, this specific subset of CD8+ T cells might contribute to acute coronary events via their pro-inflammatory and high cytotoxic capacities. Inflammation, atherosclerosis, and coronary artery disease.
