Heparin is the anticoagulant of choice for measuring pH, blood gases, electrolytes, and ionized calcium. However, heparin should not be used for coagulation or hematology tests. Three heparin saltsare most commonly used for blood sample collection: sodium heparin, ammonium heparin, and lithium heparin.
Correspondingly, what is the drug heparin used for?
Heparin injection is an anticoagulant. Heparin is used to prevent or treat certain blood vessel, heart, and lung conditions. Heparin is also used to prevent blood clotting during open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions.
Which tube contains an anticoagulant?
Red Stopper (serum): No anticoagulant or clot activator. Usually used by Chemistry and Mailouts. Light Blue Stopper (plasma): Contains 3.2% sodium citrate as anticoagulant. These tubes are used for coagulation studies and need to be completely filled to ensure proper ratio of blood to anticoagulant.
