Test Parameters & Specifications
Sample Stability
- Hemolyzed or clotted blood samples
- Insufficient sample volume
- Contaminated buccal swabs
- Improper labeling or documentation
Understanding Your Results
Matching alleles at high resolution reduces transplant risks such as graft rejection.
Certain HLA-B alleles are associated with increased risk or diagnosis of autoimmune conditions.
If you have symptoms of autoimmune disease or are undergoing transplant evaluation, consult your doctor for test interpretation and next steps.
Limitations
- ⚠Tests only HLA-B locus; other HLA loci may require separate tests for full compatibility
- ⚠Requires specialized laboratory and expertise for accurate results
- ⚠Results may be affected by sample quality or technical errors
Risks & Considerations
- ●Minor bruising or soreness at blood draw site
- ●Rare risk of infection at puncture site
- ●Discomfort during buccal swab collection
Interfering Factors
- ●Hemolyzed blood samples
- ●Contaminated buccal swabs
- ●Improper storage conditions leading to DNA degradation
