Question

Quizplus · Accepted Answer

D-dimer is considered to have a reliable negative predictive value in the diagnosis of DVT. When D-dimer levels are normal, it is unlikely that a patient has DVT. However, a positive D-dimer result does not confirm DVT, as it can also be elevated in various other conditions. Therefore, a positive D-dimer result should be followed up with other diagnostic tests to confirm the diagnosis of DVT. The other three options in the question (A, B, and C) are not specific laboratory tests for the diagnosis of DVT.
