HLA-DR2 [Presence] in Donor
Active
Part Description
LP16641-0 HLA-DR2
HLA-DRB1*1501 and DRB1*1503, subtypes of DR2, are associated with narcolepsy. There is a strong association between HLA DR2/DQ1 and idiopathic narcolepsy in both the Japanese and Caucasian population. Studies between the Japanese and Caucasian population have shown 85 to 90% of individuals diagnosed with narcolepsy have DR2/DQ1. In Blacks, DR5 may be present instead of DR2, however, nearly all have DQ1. The absence of DQ1 in a patient with negative clinical findings is strong evidence against the diagnosis of narcolepsy.

- Change Reason
- This test is commonly performed on cells found in saliva and buccal swabs as well as blood specimens. Changed specimen from 'Bld^donor' to 'Bld/Tiss^donor' to represent both specimen types.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
