HLA-DQ Oligotyping Interp
The presence of a disease associated HLA combination does not establish a diagnosis. If less than 2 alleles are reported for a locus, the patient is likely homozygous. Rare diagnostic errors can occur due to primer or probe site mutations. This test is not sufficient for comprehensive HLA evaluation for clinical hematopoietic stem cell transplantation. Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.
