These may include joint fluid, biopsy tissue, CSF and EDTA plasma. We recommend that specialists call RIPL to discuss appropriate sample types for PCR. If albumin, IgG and IgM measurements are not available, RIPL will make arrangements for these measurements at additional cost. If possible, please provide CSF cell count and total albumin, IgG and IgM values. įor testing for neurological Lyme disease, you must send paired CSF and serum samples taken on the same day.

The overall sensitivity of PCR on a skin biopsy of an EM or ACA rash is around 50% and is limited by the chance of a single biopsy hitting a site with a significant number of organisms. Borrelia species DNA may occasionally be detected in the blood by PCR, but a negative PCR test is of no value in excluding localised Lyme disease.
