New: DOE-SPEC-1142-2019, Beryllium Lymphocyte Proliferation Testing (BeLPT)

This specification is for beryllium lymphocyte proliferation tests (BeLPT) used for detecting whether an individual has developed a sensitization to beryllium and for clinical evaluation and diagnosis of patients for chronic beryllium disease (CBD). However, a lung biopsy is needed to fully establish the presence of CBD. This specification should be used in all contracts with laboratories for the purchase of BeLPT Services. Supersedes DOE-SPEC-1142-2001, dated 5-7-2001.
