Methodology:

Analysis of the gene sequence of the HLA-B genes for the presence of this specific variant.

Requesting the test

Ordering:

This test can be requested by any medical practitioner.

Sample required:

4 mL blood in EDTA. Specimens may be collected by the requesting practitioner or at any Sonic Healthcare collection centre (see link below).

To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.

We recommend that the patient or another adult check the labelling of request forms and sample tubes.
