Background: Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is an inflammatory biomarker for coronary heart disease and ischemic stroke risk assessment.
Methods: The Plac turbidimetric immunoassay (TIA) for measurement of Lp-PLA(2) was evaluated for limit of blank, functional sensitivity, dilution linearity, imprecision, interferences, and comparison to an ELISA assay for Lp-PLA(2).
Results: The assay was linear from 100 to 500 microg/l.
