What do the results mean? D-dimer results typically provide the following information: A positive test result is not within the typical range and may indicate the presence of blood clots. A...
A positive or elevated D-dimer test result may indicate that you have a blood clotting condition, but it doesn’t guarantee that you have one. A D-dimer test can't reveal what type of clotting condition you have or where the clot is located in your body.
In adult patients with a clinically low pretest probability (Wells score) of developing DVT, a negative D-dimer test result yields a 99% negative predictive value (NPV) in patients aged 60-80...
Abnormal results on a D-dimer test warrant further testing. This can include Doppler ultrasound, computed tomography (CT) angiography, or lung ventilation-perfusion (V/Q) scan. Treatment depends on the cause of high D-dimer levels but typically includes statins or blood thinning medications.
A D-dimer test helps measure your risk for blood clots. An elevated D-dimer level may indicate a risk for pulmonary embolism or deep vein thrombosis. Learn what the normal range is, with GoodRx.
Obtaining a D-dimer can help in exploring the differential diagnosis in patients who present with symptoms or signs such as chest pain, shortness of breath, or hypoxia. Based on the Wells Criteria, patients can be risk-stratified into low-risk, moderate-risk, or high-risk for PE.
What does a high D-dimer level mean? If your result is high or positive, it means there are high levels of D-dimer protein in your blood.
Learn what to expect and how to prepare and interpret your D-dimer test results. A D-dimer test is a blood test that helps detect the presence of blood clots in the body.
If your results show higher than normal levels of D-dimer, it may mean you have a clotting disorder. But it cannot show where the clot is located or what type of clotting disorder you have. Also, high D-dimer levels are not always caused by clotting problems.
High D-dimer test results do not always mean you have a clotting condition. What is a D-dimer normal range? Different labs use different measurements for D-dimer testing.
