Status Information

Status
DISCOURAGED
Comment
Most labs no longer perform SRA tests using LMW heparin since specimens with certain antibodies are known to cross-react with low molecular weight heparins. If negative or inconclusive, they would need to repeat testing using UFH.

50728-5 Serotonin release 0.1 IU/mL heparin.unfractionated [Units/volume] in Serum

Term Description

Resulted as percentage of specific serotonin release: (cpm test - cpm spont)/(cpm max - cpm spont) x 100, where cpm "spont" is the spontaneous release of [3H]serotonin from cells incubated in absence of antibodies, and cpm "max" is the maximum release of [3H]serotonin from cells lysed using 1% Triton X-100.
