Does neg d diner rule out dvt?

Neg d dimer=no clots. A positive d-dimer is non diagnostic and can be elevated from many causes not only clots. A negative d-dimer is indicative of no clots. However. the gold standard to evaluate DVT of the legs is a venous duplex ultrasound. If DVT is strongly suspected,then I would first do a venous ultrasound and not rely solely on the D-dimer.
Not necessary. you still could have a DVT but probably do not have one It is used with other tests to rulle in or rule out a DVT or PE If you have worries please be seen.
Not necessarily. A negative d-dimer is a fairly sensitive test to rule out acute clotting or inflammation but it does not rule out the possibility of a chronic occlusion.

I had two neg. D dimer tests, but my legs are killing me. I never had a DVT ever but is it worth it to get an ultrasound to be sure?

Multiple causes. See your pcp and be guided as to arterial, venous, or musculoskeletal. Or see a vascular surgeon before spending time and dollars on unnecessary testing. Read more...
Probably not. The d-dimer test is very sensitive - meaning it is extremely unlikely to be negative if there is any blood clot or dvt. You need to see your doctor to workup your leg pain so that it can be properly diagnosed and treated. That may involve consulting other specialists, such as neurology or perhaps vascular surgery.

Yes. There are many causes of leg pain and DVT is only one. D-Dimer is not sensitive enough to exclude all blood clots and it does not evaluate for venous insufficiency. A duplex for both obstruction and insufficiency to evaluate your deep and superficial veins is a good start. There are other causes of leg pain such as myositis, referred pain from nerve compression etc that a doctor can help with. Read more...

Not necessarily. The gold standard for DVT is a venogram. If the suspicion or DVT is high I would do a venogram. If the suspicion is low d-dimer might help to confirm no assert the negative results in the US. Read more...
Not necessarily. If the ultrasound was technically proficient than it's unlikely that a clot caused the swelling. By the way, what did the ultrasound characterize the swelling as. Also, if the swelling is truly on the front(anterior) side as seem to be suggested as above, then it's unlikely a clot as those issue tend to present more so on the "back" side of the leg.

Is d dimer reliable for excluding DVT pe low risk?

D-dimer . YES. In rare cases if you have factor XIII deficiency, or the tube was incorrectly filled ,if it is more then 10 days since the event, or use of anticoagulants it may give a false negative but otherwise it is fairly specific for excluding PE/DVT especially if you have not had a previous DVT/PE do not have shortness of breath fast heart rate, calf swelling cancer , recent surgery or travel.

D dimer risk. D-dimer has a high negative predictive value to rule out DVT when risk is low. When risk is high, it is less reliable and ultrasound is better relied upon to exclude DVT. Read more...

D-DIMER. D-dimer is significant when it is negative since it excludes clot formation. A positive d-dimer, however, is not diagnostic of a clot since it can be positive for other reasons. In a low risk patient with a negative d-dimer, the chances of a DVT are very low. Read more...

Very low. D-dimer assay had good sensitivity and negative predictive value (NPV), but low specificity, especially in patients who may have had a positive result for reasons other than DVT or PE. Pulmonary embolism can be safely excluded on the basis of a Wells score of ?4 combined with a negative D-dimer, with a failure rate of less than 2%, which is considered safe by most published consensus statements.
