Clear Test D-dimer

Open the foil package and place the test device on a clean, flat surface.

 

  The best results are obtained when the test is carried out directly after opening the foil packaging

  Take finger-prick blood sample: Wash the patient's hand with soap and warm water or clean with alcohol and let it dry. Massage the hand without touching the puncture area by rubbing the hand towards the fingertip of the middle or ring finger pierce the skin with a sterile lancet. Wipe away the first blood. A venous sample can be taken as an alternative.

  Hold the delivered pipette horizontally and gather sufficient blood for the test.

  Let 2 drops of whole blood (about 40 ul) fall in the middle of the test. Immediately add 1 drop of buffer solution and start the timer.

  Leave the test device horizontally and wait for the coloured line(s) to appear. Read the results after 10 minutes (although positive results can sometimes be seen earlier).

 Do not interpret results after 15 minutes.

Pulmonary embolism risk score (≥ 4.5) or D-dimer positive or elevated: increased risk of pulmonary embolism; refer to the internist and pulmonologist.



DVT

DVT risk score (≤ 3) and D-dimer negative or normal: DVT sufficiently ruled out.

DVT risk score (≥ 4) or D-dimer positive or elevated: request a two-point compression ultrasonography for the same day and inform how the radiologist can reach the GP.
