Serum Lipoprotein (a) Measurement by Latex Immunoassay

Abstract

Serum lipoprotein (a)(Lp (a)) concentration was measured by latex immunoassay (LIA) with Hitachi 7150 auto analyzer.
The range of assay was 10-1000mg/l and the lower limit was 6.4mg/l.
Within-run and day-to-day coefficients of variation were 1.64-3.14% at 74.0-456.1mg/l and 2.68-5.75% at 75.2-463.6mg/l, respectively.
There was no-interference from the high concentrations of hemoglobin, bilirubin and plasminogen. The normal range for serum Lp (a) established measuring sera from 187 healthy subjects including 94 women and 93 men, was 126.9±113.0mg/l.
