CD-57 Score

December 3rd, 2009 No comments

Focus of this post:  CD-57 is a very useful marker of immune system function and progress in treatment.

The CD57 cells are a subset of cells in the immune system. Lyme disease really attacks these cells and a measurement of these cells can be used to verify Lyme, and to monitor recovery. A normal score is 200, someone who has Lyme would be below 60, and less than 20 represents severe illness.

My CD57 on November 19, 2008 was 15.6
My CD57 on June 4, 2009 was 34 (Yeah, it’s going up!)
My CD57 on November 25, 2009 was 102 (Wow, that’s quite an increase in one year!)

In immunology, the CD57 antigen (CD stands for cluster of differentiation) is a protein which is also called HNK1 (human natural killer-1) or LEU7.
