Narcolepsy evaluation
Narcolepsy evaluation-994
HLA DQB1*06:02 and HLA DQA1*01:02 are associated statistically with narcolepsy and are sometimes used as tests in support of that diagnosis.
Even with appropriate precautions, an occasional specimen may not be satisfactory for testing. In such cases, fresh specimens should be collected for retesting. Narcolepsy-associated HLA alleles are not diagnostic, but they are useful in stratifying risk.
Immediatley following collection, mix sample by inverting 8 - 10 times to prevent clotting
Maintain specimens at room temperature. Protect from extreme heat or cold.
