Interpretive Data
This test is intended for use as one component of a clinical algorithm for determining the likelihood of venous thromboembolism (VTE) in an outpatient setting. Patients with negative values are unlikely to have VTE; however, false negatives may occur more commonly in patients with cancer. Positive results are not useful due to the poor positive predictive value of the test. This test is not currently available for inpatient testing due to low specificity. This test is not useful for diagnosing or following patients with DIC. The cutoff value is greater than or equal to 0.5 µg/mL (Fibrinogen Equivalent Units).
