The sequence of blood collection with vacuum blood collection tubes requires certain specifications. The purpose of standardizing blood collection is to ensure the quality of specimen collection and reduce the mutual influence between different test tubes. According to the regulations and experience in the health industry standard WS/T225-2002 "Clinical Chemistry Test Blood Specimen Collection and Processing", it is recommended that the blood collection sequence of blood collection tubes is as follows:

Blood culture bottle (anaerobic priority)-no additive tube (red, golden yellow tube)-suspect blood test tube (blue)-other anticoagulant tube (black, green, purple, gray), syringe         2. Syringe blood sampling sequence

In order to avoid the blood staying in the syringe for too long, causing the blood to agglomerate slightly, the blood sampling sequence is slightly changed as follows!

Blood culture bottle (anaerobic priority)-coagulation test tube (blue)-other anticoagulant tubes (black-green-purple-grey)-no additive tube (red, golden yellow tube)
