| ○ CSF ○ Synovial fluid ○ Biopsy tissue (fresh or paraffin-embedded) |
Other Information
○ PCR testing is not sensitive on specimens other than synovial fluid.
○ Serology is the primary test to diagnose Lyme.

○ CSF/synovial fluid: sterile container (min volume 0.5 mL)
○ Tissue: sterile container (0.5g)
○ Tissue: sterile container (0.5g)
CSF:
○ Decontaminate skin, collect at least 0.5 mL of CSF for each test into a sterile container. Collect appropriate amount of CSF for each additional test requested.
Synovial fluid
○ Clean the needle puncture site with alcohol, and disinfect it with an iodine solution or Chlorhexidine antisepsis. Aseptically perform percutaneous aspiration with syringe and needle to obtain synovial fluid. Transfer to sterile container.
Biopsy tissue
○ Collect 5-10 mm3 tissue aseptically using surgical technique/punch biopsy. Place in a clean, sterile container with a small amount of sterile saline.
