Does hemolysis affect d dimer
WebA D-dimer test is a blood test that checks for, or monitors, blood-clotting problems. A positive test means the D-dimer level in the body is higher than normal and suggests someone might have blood clots. This test measures the amount of D-dimer, a type of protein the body produces to break down a blood clot. WebTo help clinicians better target testing, this study sought to quantify the effect of risk factors for a positive quantitative D-dimer in patients evaluated for PE. Methods: This was a …
