D) Anticoagulation

Question

Quizplus · Accepted Answer

Centrifugation is the most commonly used method to concentrate specimens in the microbiology laboratory. This can increase the recovery of pathogens in the specimen and improve the sensitivity of diagnostic tests. Homogenization and mixing can also be used to ensure even distribution of the specimen, but they do not concentrate the sample. Anticoagulation is used to prevent blood from clotting, but it does not contribute to the concentration of the specimen.
