Specimen Collection Criteria

Collect: One Gold-top SST tube. (Minimum Whole Blood: 6.0 mL)

Physician Office/Draw Specimen Preparation

Preparation for Courier Transport

Transport: Centrifuged collection tube, refrigerated (2-8°C or 36-46°F). (Minimum Serum: 1.5 mL)

Rejection Criteria

• Plasma specimens.
• Severely lipemic, icteric, or hemolyzed specimens.  

In-Lab Processing

Let specimen clot 30-60 minutes then immediately centrifuge to separate serum from cells. Room temperature is acceptable for a maximum of two hours. (Minimum Serum: 1.5 mL)

Laboratory

Royal Oak Special Testing Laboratory

Performed

Tuesday, Friday.
Results available within 3 business days.

Reference Range

Negative:  ≤ 0.8 U
Equivocal:  0.9-1.0 U
Positive:  ≥ 1.1 U

Test Methodology

Multiplex Flow Assay

Interpretation

A negative test result indicates that both IgG and IgM are negative. A positive test result indicates that IgG, IgM, or both are positive. All positive and equivocal results are sent out for Lyme Immunoblot testing. Prompt antibiotic treatment can interfere with specific antibody responses.

Clinical Utility

This assay aids in the diagnosis of infection with B. burgdorferi.
