Participants’ Portal Results Entry Guidance – Scheme 1B

HLA-B27 Testing

Indicate your result by selecting from the dropdown box.

An ‘equivocal’ report is accepted for laboratories that are unable to determine a positive or negative result (i.e. by flow cytometry) and their normal clinical procedure would be to refer the sample to another laboratory. ‘Equivocal’ results will not be assessed. Technical failures and other issues should be reported as ‘Not Tested’.

If you are using a molecular typing method please state which HLA-B*27 alleles/allele groups, if any, were detected in the comments box– this is used for Participant information only.

Technical issues/invalid results (e.g. control failures, quality issues) should be reported as ‘Not tested’.  Reasons for not testing need to be reported on the final result entry page. ‘Not tested’ results will not be assessed.
