Triage PlGF Test (Quidel)
The Triage PlGF test is a single-use, fluorescence immunoassay device, which is used with the CE-marked Triage MeterPro point-of-care analyser. Blood must be centrifuged, and plasma extracted before testing. The analyser can be installed either as a point-of-care test in a clinic or ward, or in a laboratory, and the assay takes 15 minutes. It detects PlGF-1 and quantifies concentration in the range of 12 to 3000 pg/ml. It is recommended by the National Institute for Health and Care Excellence as a rule-out test for suspected pre-eclampsia between 20 and 34+6-weeks’ gestation at a threshold of 100 pg/ml.13
