Do I have to see a specialist to get a d dimer ordered?

Do I have to see a specialist to get a d dimer ordered?

Not necessarily..: A d-dimer test is usually obtained when a blood clot diagnosis is considered. The test is very non-specific in that many things besides a blood clot can result in a positive test. If the d-dimer is negative, the chances of having clinically significant clot is very small. So, in terms of diagnosis, a negative test is actually more helpful. The test can be ordered by any doctor. ...Read more

D Dimer (Definition)

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 ...Read more

My NEICE d dimer test came back high 2.3 high. She has a crohn disease. Does she need to see any specialist and who ?

Nonspecific: A d-dimer is a nonspecific blood test that can be indicative of many things. Sometimes it can be a clue pointing towards active inflammatory bowel disease. Inactive chrons disease can be managed by a general practitioner but if symptomatic disease is best managed by a gastroenterologist. ...Read more

Is there any specialist doctor I can go to for making sure I dont have a blood clot in my arm? My doc thinks d dimer 0.55 is normal but I don't

DVT arm: Many things can elevate D Dimer. If you have pain or ongoing swelling in your upper extremity, I recommend that you get a venous Duplex scan in an accredited vascular lab and also get a specialist opinion from a phlebologist or vascular surgeon. ...Read more

Why is it so difficult to get a venogram below the knee? D-dimer and US are not good enough considering I have PV. Self assessment 3 on Well's test

Skill, risk and time: Venogram is an effective way to evaluate the veins of the leg especially to look for blood clots.Unfortunately we do these tests less often because they are technically more difficult , take more more time and have more risk. IV contrast dye can damage kidneys and cause phlebitis. So because the done so infrequently the skill get a bit rusty and we prefer newer less invasive methods for diagnosis ...Read more

Why do anticoagulants sometimes cause a false negative D Dimer? If the thin the blood and don't affect FDP I don't see why they would cause an effect?

Why do anticoagulants sometimes cause a false negative D Dimer? If the thin the blood and don't affect FDP I don't see why they would cause an effect?

Different : FSP and D Dimer are not synonymous.. D dimer is a by-product of clots and when the anticoagulants prevent formation or clots, d-dimer will be low or falsely negative. D-dimer off anticoagulation can rough predict the risk of recurrent clots. ...Read more

Polycythemia vera verified by second opinion. + Crohn’s. Unilateral calf swelling. Unilateral superficial vein. D-dimer + US normal. Get venogram?

Polycythemia vera verified by second opinion. +  Crohn’s. Unilateral calf swelling. Unilateral superficial vein.

D-dimer + US normal. Get venogram?

Difficult to know: Polycythemia vera and Chrons are both risk factors for DVT . Also your sign and symptoms are suspicious for DVT. Venous Doppler US for a single exam may miss small DVT especially in the calf. D dimer if normal pretty sensitive. Many options repeat: Ultrasound and possibly d dimer, venogram [but these are not done much now], follow closely. Recommend close follow up with your doctor/ vein expert. ...Read more

Er nurse encouraged nuclear scan for positive d dimer in patient. Family member had declared dnr and said no heparin if positive. Why get the test?

Er nurse encouraged nuclear scan for positive d dimer in patient. Family member had declared dnr and said no heparin if positive. Why get the test?

Get Nuclear Scan : Before cardiac arrest, treat patient as this is not a hospice or "comfort care only" patient yet. Offcourse, goals of care need to be discussed with the patient and primary decision maker/proxy but pulmonary embolism is a high symptom burden disease, diagnosis will lead to treatment (which could be low dose coumadin), which will further prevent embolism extension, severe breathlessness and pain. ...Read more

Will a d dimer and car scan show a DVT anywhere in your body ? And can you get a DVT 3 months post C-section ? Or is that to far out !?

Will a d dimer and car scan show a DVT anywhere in your body ? And can you get a DVT 3 months post C-section ? Or is that to far out !?

No....: A D-Dimer can be positive for many reasons besides a DVT. And, a CT scan does not diagnose clot "anywhere in the body". A chest CT-angio can show clot in the blood vessels of the lungs and a VQ scan is sometimes helpful as well. An ultrasound of the extremities can show clot there. And, a blood clot can happen any time if risk factors are present. See a doctor for diagnosis. ...Read more
