LifeLabs to offer flow cytometric immunophenotyping for HLA-B27 antigen testing

February 19 2020
Starting on March 9th, 2020 we will offer flow cytometric immunophenotyping for HLA-B27 antigen testing.

LifeLabs is pleased to introduce an expansion of our flow cytometry testing.  Starting on March 9th, 2020 we will offer flow cytometric immunophenotyping for HLA-B27 antigen testing.  Flow cytometry is widely used for analyzing the expression of surface and intracellular molecules in order to differentiate and characterize different cell populations. 

LifeLabs’ test kit includes five different monoclonal antibodies specific for the HLA-B27 antigen for increased sensitivity.  Any inconclusive result will be confirmed by molecular testing.

How to order:

  1. On the OHIP requisition enter ‘HLA-B27 typing’ under the “Other” category.  Send the requisition with the patient to any LifeLabs collection centre.

LifeLabs collects these samples at any location on Monday – Thursday (no collection on Friday) and the turn-around-time for this testing is 2-4 business days.

Should you have any questions about HLA-B27 testing at LifeLabs, please do not hesitate to contact:
