Which tube contains anticoagulants?
Keeping this in view, what color tubes contain anticoagulants?
Certain colored tubes contain anticoagulants that prevent the blood from clotting. Once the blood is collected from the body, it will start coagulating immediately unless special measures are taken to prevent the coagulation. The common colors containing anticoagulants include lavender, green, blue, Lt. Blue and grey.
Subsequently, question is, what blood tube colors are for which test? Green top tube with sodium or lithium heparin: used for plasma or whole blood determinations. EDTA tubes: includes Lavender top, Pink top (used for blood bank testing), Tan top (used for lead testing), and Royal Blue top with EDTA (used for trace metal whole blood or plasma determinations).
In this manner, which tubes are anticoagulants?
Green-top tube (sodium heparin): Tube contains sodium heparin as an anticoagulant. This tube is used for preparing heparinized plasma, whole blood, and bone marrow specimens. Note: Tube should be inverted several times immediately after blood collection to prevent coagulation.
Which tube is used for PTT?
Blue-Top Tube - Sodium Citrate (NaCitrate): This tube is primarily used for coagulation studies (PT and PTT). Complete filling of this tube is essential to obtain accurate results.
