I was in the er back in Jan for chest pains, and they did a d-dimer, that came out elevated at 2.48, and so they checked my lungs for any embolism, and everything checked out ok..... so does that mean, I possibly have a clot somewhere and don't know it? Or could this be elevated for other reasons? Should I be concerned? The dr. never mentioned it at all, I just saw it on my records... and I canot find out how high 2.48 is, etc. any info would be appreciated:)

Thanks

D-dimers look at clots, as you suggest. Your level of 2.48 without a measurement doesn't give us an idea of which test kit your doctor used, and thus the reference range (it looks like it is in ug/mL). As well, D-dimers are affected by age and other history details.

You could potentially have a clot, but your physician should be able to tell you more. Sorry for the late reply.

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
D dimer has only negative predictive value. Its useful in excluding thrombosis. However, if its positive and patient is symptomatic then specific workup should be done.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
