Question 1

can inflammation from a severe lupus flare cause an elevated d dimer of 1600? crp over 200. esr 50.

Accepted Answer

See below: Elevated CRP and ESR can be signs of lupus glare up. Lupus can cause hypercoagulable state (meaning you can form clots in the body even if you don't need to). D- dimer is a test for to check for by products of clots in the body. Elevated d dimer needs to be attended by doctor asap.

Question 2

i have joint pain same on both sides of my body, fatigue, low grade fevers, elevated crp, elevated d dimer. tested for ra and lupus both neg. ?

Accepted Answer

See a rheumatologist: You need to be seen by a specialist in immunology, infectious diseases, or joint diseases.  This is not a simple answer but would require an extensive evaluation.

Question 3

i had an uedvt 7 years ago. now i apparently have another but have neg d dimer. is it possible the u/s was read wrong and i don't have a clot?

Accepted Answer

DVT: It is possible the ultrasound is wrong, but it is also possible that you have a DVT and normal d-dimer as well. I would repeat the ultrasound. If they aren't 100% sure on the u/s, a venogram can be done but is probably not necessary.  You need a hematologic work up to see why you are hypercoagulable.

Question 4

what is a ?d-dimer test?

Accepted Answer

Thrombosis: The d-dimer is a fibrin degradation product (or fdp) which represents a small protein fragment in blood after a blood clot is broken down. The value can be used to test for clotting or thrombosis problems. However, a single value or a value in isolation should not be used.

Question 5

d dimer--how effective is this test?

Accepted Answer

Efficacy of d-dimer: That is actually a hard question to answer.  There are different testing methods and some d-dimer tests are more reliable than others.  If you have a low probability of having a blood clot by history and a low d-dimer, it is pretty safe to say that you don't have a blood clot.  If you have a high d-dimer and a high probabilty of a blood clot by history, then your risk of a clot is high.

Question 6

how sensitive is d dimer negative at 178 ?

Accepted Answer

Pretty good: A negative D dimer can strongly rule out a PE but I never like to say never in medicine. Kim not sure what your symptoms are but if you are still concerned for a Pulmonary embolus than further work up could be warranted. Personally, unless you had high probability I would not proceed any further.

Question 7

what is the definition or description of: d dimer?

Accepted Answer

Marker for clot: D-diner is a breakdown product from blood clots. It can be found elevated in certain conditions like pulmonary embolus (blood clot which travels to the lung) deep venous thrombosis (blood clot in deep vein of legs usually) and disseminated intravascular coagulation (diffuse clot formation from severe infection which actually leads to bleeding).

Question 8

what can cause d-dimer to be high while on warfarin?

Accepted Answer

Warfarin does not: Lower ddimer levels.

Question 9

how often are d dimer blood tests falsely negative?

Accepted Answer

Decision levels: There is no simple "positive" or "negative" for a D-dimer. A value is reported to a physician and he/she uses this to gauge the likelihood of a thrombus / DIC.

Question 10

panicky because two weeks ago d dimer was 78 now 172 cut off 250?

Accepted Answer

Why so many tests?: sounds like you need to talk with your physician about what is bothering you that is causing all these test to be done D dimer is very non specific, there are many reasons for it to be high. When it is NORMAL DVT is very unlikely but it can be ELEVATED for many reasons. You seem to be placing too much emphasis on one test that is very non specific
