Not acceptable

Specimen Transport:

Transport specimen to UWHC Hospital Laboratory.

Interpretation:

A written interpretive report will be provided.

Test Limitations:

Identification of HLA alleles generally at the single allele level. Certain combinations may not be resolvable to allele-level identification.
