GENERAL INFORMATION
Expected TAT 3 - 7 days  
Clinical Use High resolution HLA typing is preferred for matching of bone marrow transplant donors and recipients. Other clinical indications may require high resolution typing to rule out alternative allele combinations.
High resolution typing for DQB1 will meet the following criteria: All ambiguities within exons 2 and 3 will be resolved. Those ambiguities that remain will be reported as an allele code. This test is for single locus typing at high resolution. 
Notes Sequence-based typing (SBT), sequence-specific oligonucleotide probes (SSOP), and/or sequence-specific primers (SSP) as needed to obtain the required resolution.
