Additional Codes

Mayo Test ID
LYMPV


Ordering Guidance


This assay does not detect Borrelia miyamotoi. If infection with this organism is suspected, order BMIPB / Borrelia miyamotoi Detection, PCR, Blood or BMIYC / Borrelia miyamotoi Detection, PCR, Spinal Fluid.



Necessary Information


Specimen source is required.



Specimen Required


Submit only 1 of the following specimens:

 

Specimen Type: Spinal fluid

Container/Tube: Sterile vial

Specimen Volume: 1 mL

Collection Instructions: Label specimen as spinal fluid.

 

Specimen Type: Synovial fluid

Container/Tube: Sterile vial

Specimen Volume: 1 mL

Collection Instructions: Label specimen as synovial fluid.

 

Specimen Type: Tissue (fresh only)

Sources: Skin or synovial biopsy

Container/Tube: Sterile container with normal saline

Specimen Volume: Approximately 4 mm(3)

Collection Instructions:

1. Submit only fresh tissue.

2. Skin biopsies:

a. Wash biopsy site with an antiseptic soap. Thoroughly rinse area with sterile water. Do not use alcohol or iodine preparations. A local anesthetic may be used.

b. Biopsy specimens are best taken by punch biopsy to include full thickness of dermis.

3. Label specimen with source of tissue.


Useful For

Supporting the diagnosis of Lyme disease in conjunction with serologic testing

 

Specific indications including testing skin biopsies when a rash lesion is not characteristic of erythema migrans and testing synovial fluid or synovium to support the diagnosis of Lyme arthritis

 

This test should not be used to screen asymptomatic patients.

Testing Algorithm

Method Name

Real-Time Polymerase Chain Reaction (PCR)/DNA Probe Hybridization

Reporting Name

Lyme Disease, PCR, Varies

Specimen Type

Varies

Specimen Minimum Volume

Spinal Fluid: 0.3 mL; Synovial Fluid: 0.5 mL; Tissue: See Specimen Required

Specimen Stability Information

Specimen Type Temperature Time Special Container
Varies Refrigerated (preferred) 7 days
  Frozen  7 days

Reject Due To

  All specimens will be evaluated at Mayo Clinic Laboratories for test suitability.

Reference Values

Negative

Reference values apply to all ages.

Interpretation

A positive result indicates the presence of DNA from Borrelia burgdorferi, Borrelia mayonii, Borrelia afzelii, or Borrelia garinii, the main agents of Lyme disease.

 

A negative result indicates the absence of detectable target DNA in the specimen. Due to the clinical sensitivity limitations of the polymerase chain reaction assay, a negative result does not preclude the presence of the organism or active Lyme disease.
