Is A Positive D-dimer Test Result For Blood Clot Enough To Diagnose Pulmonary Embolism Or Deep Vein Thrombosis?
I would explain as follows:
I read carefully your question and would explain that D-Dimmer test is not a specific or sensitive test for pulmonary embolism or deep vein thrombosis.
The false positive elevation of D-Dimmer could be related to other possible causes like inflammation or an infection, liver disease, a trauma or recent surgery, pregnancy, malignancy, etc..
If the Doppler ultrasound of the leg vessels and the pulmonary angio CT scan result normal, the diagnosis of pulmonary embolism or deep vein thrombosis can be excluded and there is no need for treatment.
So, just relax and don't worry about it!
I would recommend performing a Doppler ultrasound of the leg vessels, if you have not performed it yet. Anyway, if you do not have any symptoms like leg pain or swollen leg, there is nothing to worry about.
Hope you will find this answer helpful!
I would recommend as follows:
Considering your swollen legs, I would recommend performing a leg vessels Doppler ultrasound.
Other tests to investigate for the possible causes underlying swollen legs are needed:
- a cardiac ultrasound and NT pro BNP levels for heart failure
- kidney and liver function tests
- blood electrolytes
- complete blood count, PCR, ESR for inflammation.
Hope to have been helpful!
Wishing good health,
