D- dimer is a protein fragment that is produced when a blood clot dissolves in your body.
D-dimer Test is a blood test often used to measure and assess clot formation.D-Dimer level is tested using immunoturbidimetric assay with refence range of 0-0.50mg/L.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
The presence of D-dimer in the blood plasma, which has a half-life of roughly 8 hours until kidney clearance occurs, is often used as a clinical biomarker to identify thrombotic activity and therefore diagnose conditions like pulmonary embolism (PE), deep vein thrombosis (DVT), venous thromboembolism (VTE) and disseminated intravascular coagulation (DIC) and coronary artery disease.
There are currently four major types of commercial assays that can be used to measure D-dimer levels, of which include whole blood analysis, enzyme-linked immunosorbent assay (ELISA), enzyme-linked immunofluorescence assay (ELFA) and Latex-enhanced immunoturbidimetric assay.
As Covid-19 patients has high risk of developing renal failure,venous blood clots and other complications associated with blood clots such as stroke.So elevated levels in D-Dimer test is used as a biomarker for disease severity.
It is estimated that COVID-19 patients will experience critical forms of this disease that progress to severe cases with respiratory distress syndrome, coagulation dysfunction, multiple organ failure, etc.Therefore, early identification of the severity is very important to the clinical diagnosis of and treatment for COVID-19.
