HLA‑B Low Resolution
Use
HLA‑B low resolution typing is used to determine broad HLA‑B antigen groups, commonly for transplant compatibility screening or matching donor/recipient HLA‑B loci.
Special Instructions
Not provided.
Limitations
Low resolution typing may not resolve allelic ambiguities and provides only broad antigen-level information. Additional high-resolution typing may be required for definitive matching. Certain specimen types (e.g., frozen or heparinized/citrated tubes) are not acceptable.
