QUESTION
Which of the following is anticoagulant?
OPTIONS
(A) Sodium hydroxide
(B) Potassium hydroxide
(C) Sodium citrate
(D) Sodium tartrate
ANSWER
(C) Sodium citrate
EXPLANATION
Sodium citrate is an anticoagulant that binds ionized calcium reversibly and is therefore widely used for coagulation studies. Sodium hydroxide and potassium hydroxide are strong alkalis rather than standard anticoagulants, and sodium tartrate is not the routine anticoagulant represented here. Hence, option C is correct.
