The best lab test to diagnose disseminated intravascular coagulation (DIC) is:
A. platelet count.
B. protime (PT).
C. partial thromboplastin time (PTT).
D. D-dimer.
Correct Answer: D
Explanation/Reference:
Explanation:
In DIC, many small clots form throughout the body and are immediately broken down. D-dimer measures a specific fibrin split (or degradation) product and is the most specific test for DIC. Choice 1 is incorrect because platelets are consumed in DIC, but this is not specific. Choices 3 and 4 are both elevated (because clotting factors have been used up) but, again, are not specific.Physiological Adaptation
