Lyme Disease - Serology
Specimen Type:



​Blood, clotted - vacutainer tubes (SST)  with gel sediment

Collection information:

​Instructions for using SST tubes are found in the document titled: LAB-SD-008, Blood Collection using Serum Separator Tubes.

Minimum volume required:

​5.0 ml blood or 1.0 ml serum


​Complete all fields of the General Test Requisition Form: include the patient's full name, date of birth, Health Card Number (must match the specimen label), physician name and address,

•Enter Borellia burgdorferi or Lyme disease under ‘Test description’ on the PHO General Test Requisition.  If European Lyme disease testing is required:  enter 'European Lyme disease'

• Date of onset
• Date of collection
• Clinical signs and symptoms
• Travel history
• Exposure (e.g. tick bite)

When a European Lyme is suspected, European Lyme serology should be specifically stated on the requisition along with travel history including location and dates.


​Haemolysed, icteric, lipemic or microbially contaminated sera or plasma are not recommended for testing.

Preparation prior to transport:

​Centrifuge if using SST. Label specimens with at least two identifiers; place it in biohazard bag and seal. Specimens should be stored at 2-8°C following collection and shipped to PHOL on ice packs.

Special Instructions:

​An acute (collected early after the onset of symptoms) and a convalescent (collected 6 weeks later) may be required for laboratory diagnosis. 


​PHL performs tests for antibody to Borrelia burgdorferi using a two-tier test method as recommended by the Canadian Public Health Laboratory Network. 

Initially, a specimen is tested for total antibodies using a VlsE1/pepC10 Borrelia (Lyme) IgM/IgG ELISA. A specimen that is either reactive or indeterminate by ELISA will be further tested for IgM and IgG specific antibodies using western blot assay.

Any requests for European Lyme will be forwarded to National Microbiology Laboratory (NML) for western blot testing for antibodies to B.garinii and B. afzeli – the strains of Borrelia found in Europe. 

NML offers PCR testing for B. burgdorferi on CSF and tissue with prior approval.




​• Non‐reactive results: less than seven days
• Reactive results: within 14 days
• European Lyme request requiring confirmation at NML: 21 days


​Results are reported to the ordering physician or health care provider as indicated on the requisition.

Specimens that are positive for Borrelia species antibodies are reported to the Medical Officer of Health as per Health Protection and Promotion Act.
