Question

Quizplus · Accepted Answer

When a specimen clots,many of the pathogens are trapped inside the clotted blood.This makes it more difficult to determine the cause of the infection.Anticoagulants do not dissolve bacterial cell walls,but they do have a certain degree of antimicrobial properties.So very small amounts must always be used to ensure that this compound does not kill any bacteria present in the specimen.
