Standard range for d dimer normal values.
D dimer range for dvt.
The article below will provide you with information on the normal plasma levels of this degradation product.
D dimer a small protein fragment is found in blood only during the clotting process.
D dimer measurement is a very important step in vte diagnosis as it allows clinicians to rule out the disease in around 30 of outpatients with suspected dvt or pe.
D dimer values or 500 ng ml feu may be used in conjunction with clinical pretest probability to exclude deep vein thrombosis dvt and pulmonary embolism pe.
However using the simplired assay the 3 month incidence of dvt with a negative d dimer results and low pretest probability was 0 5 but the incidence was 3 5 with a negative d dimer and an intermediate pretest probability.
Otherwise it is normally undetected.
The normal amounts for d dimer in the blood should be around 0 5 mg l of blood or 500 ng ml of blood.
The range of d dimer levels associated with everyday living that is in people who do not have a pulmonary embolus deep vein thrombosis or any other medical condition involving an abnormal degree of blood clotting is relatively wide.
We measured d dimer using the hemosil assay for which the upper limit of normal at the time of this study was 250 ug l.
When its presence in the blood rises it suggests an increase in the formation and breakdown of clots.
A d dimer test is extremely useful in diagnosing deep venous thrombosis or pulmonary embolus both clotting disorders in an individual.
However certain other conditions in which blood clots have a role to play can also be diagnosed by.
It reflects ongoing activation of the hemostatic system.
A normal d dimer test result will reveal a negative result which indicates that thrombosis has not occurred.
D dimer in the top quintile of the d dimer distribution ranged from 1891 to 64 809 μg l that is from 7 5 to 260 times upper limit normal.
D dimer is the degradation product of crosslinked by factor xiii fibrin.
The reference concentration of d dimer is 250 ng ml or 0 4.
A d dimer test is a form of a blood test which is done to identify any blood clots that may be forming in the vascular system of the body of an individual.
