dipyridamole,
argatroban,
rosuvastatin,
atorvastatin,

pitavastatin. The
plasma sample
pretreatment method of the present invention is simple, the detection and analysis time is short, the sensitivity of the method is high, and the types and quantities of detections are many; the method is divided into a
primary screening method and a review method, which can improve the accuracy of the detection results and avoid false negative and false positive results.
