Prothrombin time (PT) and activated partial thromboplastin time (APTT) are tests that evaluate the release of specific clotting factors by measuring the time it takes for a clot to form after certain reagents are added to a blood sample.
The 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. These ranges vary from lab to lab, and your lab may have a different range for what's normal.est 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.
