What Is a Normal D-Dimer Level? What is a normal D-dimer level? A: A normal D-dimer level is less than 250 micrograms per liter, or less than 1.37 nanomoles per liter. A level in this range indicates the presence of a small amount of the substance that is released when blood clots dissolve, indicating that there is likely not a blood clotting issue.

Thromboembolism in Pregnancy Workup Twelve were diagnosed with DVT and 1 with PE. D-dimer testing (SimpliRED assay) was positive for all 13 patients (100% sensitivity), and the specificity was 60% (identifying correctly as negative for VTE 81 of 135 patients). This study demonstrated a 100% negative predictive value in pregnancy.

Understanding Your Lab Work BUN — Blood urea nitrogen. 1  Purpose: To detect elevated waste levels in the bloodstream, which is an early sign of reduced kidney function. 2  Normal range: 7 to 20 milligrams per deciliter (mg/dl). 3  How this test is conducted: A blood sample is taken and sent for analysis. Test date: Throughout the early and laterstages of CKD, including end stage renal disease (ESRD). GFR—Glomerular filtration rate. Purpose: To determine how much kidney function a person has. Normal range: 90+, with little or no protein or albumin in urine. How the test is conducted: This test is a calculation based on your creatinine level, age, race, gender and other factors. Test date: Throughout every stages of CKD, including ESRD.

- A normal test is negative. This means that you probably do not have problems with blood clotting. If you are getting the D-dimer test to see if treatment is working for DIC, a normal or decreasing level of D-dimer means the treatment is working. What Abnormal Results Mean A positive test means that you may be making blood clots. The test does not tell where the clots are or why you are making clots. Your provider may order other tests to see where clots are located. A positive test may be caused by other factors, and you may not have any clots. D-dimer levels can be positive due to: Pregnancy. Liver disease. Recent surgery or trauma. High lipid or triglyceride levels. Heart disease. Being over 80 years old.

Vitamin D Test | Home Vitamin D Blood Test Vitamin D Testing. The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D test or 25(OH)D test. Vitamin D changes into an active form of the vitamin in the kidney and can be measured through a blood test. The normal range is 30.0 to 74.0 nanograms per milliliter (ng/mL). A lower level indicates vitamin D deficiency, which you should discuss with your doctor.

D-Dimer An elevated D-dimer level is not normal. It is usually found after a clot has formed and is in the process of breaking down. If you are having significant formation and breakdown of blood clot in your body, your D-dimer may be elevated. A negative D-dimer test means that a blood clot is highly unlikely.

Testing for vitamin D These are the units that health professionals in the United States use. Elsewhere in the world, vitamin D blood test results are given in units of nmol/l. To convert a test result measured in ng/ml to one measured in nmol/l, multiply the ng/ml number by 2.5. For example, 20 ng/ml is the same as 50 nmol/l (20 x 2.5).
