See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, a low D-dimer result is more useful in excluding blood clots. A high level can be due to many reasons and is not very useful in isolation. Wish you good health!
