Q31 – 47: Optional Antigen Reporting

Questions 31-33: Number of C antigens provided

Indicate if One or Two HLA-C antigens were identified. If one antigen was identified, report the first antigen specificity in Specificity – 1st antigen.

If two antigens were identified, report the first antigen specificity in Specificity – 1st antigen and the second antigen specificity in Specificity – 2nd antigen.

Question 34: Specificity Bw4 present?

Bw4 refers to an epitope expressed by HLA-B alleles; epitopes are presented on the surface of the antigen and are recognized by the immune system. Bw4 and Bw6 are mutually exclusive and may confer reactivity with lymphocytes. Select Yes if Bw4 specificity is present. Leave blank if specificity for Bw4 was not tested.

Question 35: Specificity Bw6 present?

Bw6 refers to an epitope expressed by HLA-B alleles; epitopes are presented on the surface of the antigen and are recognized by the immune system. Bw4 and Bw6 are mutually exclusive and may confer reactivity with lymphocytes. Select Yes if Bw6 specificity is present. Leave blank if specificity for Bw6 was not tested.

Questions 36-38: Number of DR antigens provided

Indicate if One or Two HLA-DR antigens were identified. If one antigen was identified, report the first antigen specificity in Specificity – 1st antigen.

If two antigens were identified, report the first antigen specificity in Specificity – 1st antigen and the second antigen specificity in Specificity – 2nd antigen.

Question 39: Specificity DR51 present?

HLA-DR51 is an HLA-DR variant that recognizes antigens from HLA-DRB5. Select Yes if DR51 specificity is present. Leave blank if specificity for DR51 was not tested.

Question 40: Specificity DR52 present?

HLA-DR52 is an HLA-DR variant that recognizes antigens from HLA-DRB3. Select Yes if DR52 specificity is present. Leave blank if specificity for DR52 was not tested.

Question 41: Specificity DR53 present?

HLA-DR53 is an HLA-DR variant that recognizes antigens from HLA-DRB4. Select Yes if DR53 specificity is present. Leave blank if specificity for DR53 was not tested.

Questions 42-44: Number of DQ antigens provided

Indicate if One or Two HLA-DQ antigens were identified. If one antigen was identified, report the first antigen specificity in Specificity – 1st antigen.

If two antigens were identified, report the first antigen specificity in Specificity – 1st antigen and the second antigen specificity in Specificity – 2nd antigen.

Questions 45-47: Number of DP antigens provided

Indicate if One or Two HLA-DP antigens were identified. If one antigen was identified, report the first antigen specificity in Specificity – 1st antigen.

If two antigens were identified, report the first antigen specificity in Specificity – 1st antigen and the second antigen specificity in Specificity – 2nd antigen.
