HelpTest Code DIS Human Leukocyte Antigens (HLA) Class I and II Disease Association Typing, Low Resolution, Blood
Ordering Guidance
This test should be ordered if both human leukocyte antigen (HLA) Class I and Class II results are wanted for disease association.
If only needing patient's HLA Class I typing for disease association, order 1DIS / Human Leukocyte Antigens (HLA)-A-B-C Disease Association Typing Low Resolution, Blood.
If only needing patient's HLA Class II typing for disease association, order 2DIS / Human Leukocyte Antigens (HLA)-DR-DQ Disease Association Typing Low Resolution, Blood.
Specimen Required
Container/Tube: Yellow top (ACD solution A or B)
Specimen Volume: 6 mL
Collection Instructions: Send whole blood in original tube. Do not aliquot.
Additional Information: Specimen acceptability is based on extracted DNA concentration and not sample age.
Useful For
Identifying class I and II human leukocyte antigens (HLA) for potential disease associations or markers for drug hypersensitivity
