Hypercalcemia (Elevated Calcium Levels) 1 Calcium levels in the bloodstream are regulated by PTH, vitamin D, and calcitonin. 2  Hypercalcemia can vary in severity and in chronicity. 3  The main cause of hypercalcemia is hyperparathyroidism. 4  Malignancies may be associated with hypercalcemia, and the presence of hypercalcemia usually heralds a worse prognosis.

- D-dimer is the degradation product of crosslinked fibrin; therefore, it reflects ongoing activation of the hemostatic system. Since there is constant minimal physiologic fibrin formation and degradation in vivo, healthy individuals have a minimal D-dimer level.

- Among these, 539 were negative for D-dimers and 465 were positive. Mean age was 74 years (19–99 years) for patients positive for D-dimers, and 48 years (18–93 years) for patients negative for D-dimers ( ). Only 12% of patients aged 70 or above had negative D-dimers. In the group of patients positive for D-dimers, 67 (14%) had a diagnosis of either DVT ( , 3%) or PE ( , 11%).

D-dimer A negative D-dimer test will virtually rule out thromboembolism: the degree to which the D-dimer reduces the probability of thrombotic disease is dependent on the test properties of the specific test used in the clinical setting: most available D-dimer tests with a negative result will reduce the probability of thromboembolic disease to less than 1% if the pretest probability is less than 15-20%.

- 1 A low or normal d-dimer test result means that there is very little of the substance that's released as a blood clot breaks up. 2  Having very little of this substance means that a blood clotting problem isn't likely. 3  A higher-than-normal d-dimer level might mean that there is a blood-clotting problem.he d-dimer test measures the amount of a substance that is released when a blood clot breaks up. The normal values listed here (called a reference range) are just a guide.

- Test Overview. A d-dimer test is a blood test that measures a substance that is released when a blood clot breaks up. Doctors order the d-dimer test, along with other lab tests and imaging scans, to help check for blood-clotting problems. A d-dimer test can also be used to check how well a treatment is working.hy It Is Done. Doctors use the d-dimer test when a person might have a dangerous blood-clotting problem. These problems include: 1  Deep vein thrombosis, a condition in which a blood clot (thrombus) forms in the deep veins of the legs, pelvis, or arms. 2  To learn more, see the topic Deep Vein Thrombosis.

D-dimer Normal Values D-dimer normal values are biomarkers that the body’s coagulation process is not hampered with and the probability of thrombosis is lowered. On the other hand, a positive or elevated D-dimer result is an indication of thromboembolic disease and other blood disorders. Doctors often conduct follow up diagnostic tests to patients whose D-dimer values are elevated to rule out or confirm the presence of major health issues.
