PCR‐sequence‐specific oligonucleotide (PCR‐SSO) is commonly used for HLA‐typing. We recently replaced LabType SSO HD kit for HLA‐C typing with the XR kit (OneLambda, Inc.). We used 137 patients' samples representing unique most likely HLA‐C allele combinations to compare these kits' performance. The XR kit decreased the number of allele ambiguities with a median of 26.1% (first to third quartiles 20% to 36.2%, range 0% to 96.1%). The XR kit did not resolve all the common, intermediate and well‐documented HLA allele ambiguities, which may be important in the clinical setting. The XR kit eliminated 23.6% of null allele ambiguities. In conclusion, the HLA‐C XR kit provides a moderate yet valuable improvement of HLA‐typing resolution in comparison with the HLA‐C HD kit.
