The CD57 Test

Natural Killer Cell Testing for Lyme Disease

Studies have shown that natural killer cells (NK cells) play a major role in chronic Lyme disease₁. Many of those who have chronic Lyme disease have suppressed levels of natural killer cells.

The CD57 test is important to run because it can show your immune system improvements throughout Lyme disease treatment, drug or natural. As the Lyme disease-causing bacteria, Borrelia burgdorferi, is eliminated, one should see an improvement in their CD57 cells.
