An infectious disease doctor ran a CD 57 and a natural killer cell function assay on me last week. I have been on oral antibiotics for a year after a positive Lyme test. The test results came back with an 80 on the CD 57 (through Quest) and 18 on the natural killer cell. The doc tells me I do not have Lyme disease now because I am in the normal range. I still don't feel well but this doc tells me there is nothing more to do. Has anyone else had results like this and still had Lyme? Thanks
