Comment
Nearly all heparin used in serotonin release assays is porcine (made from pig intestines), including low molecular weight heparin (LMWH) and unfractionated heparin (UFH). Additionally, most labs today only use UFH since it is more likely to detect a positive result. Tests using low molecular weight heparins (e.g. Lovenox®) may cross-react with antibodies present in a patient's sample, resulting in weak or inconclusive results. Because it is important to identify the type of heparin used in the assay and porcine heparin is ambiguous in that it could represent either LMWH or UFH heparin, we are deprecating the porcine heparin terms.

50727-7Serotonin release 100 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.
