What can an elevated d dimer mean when CT scan stress test and echo were all normal but I still feel ill and tired?

What can an elevated d dimer mean when CT scan stress test and echo were all normal but I still feel ill and tired?

Inflammation: D-dimer is more useful when negative, as a negative test more or less rules out thrombo-embolism. There are many causes for elevated d-dimer, including inflammation. ...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

What else can elevated d dimer mean besides blood clot?

What else can elevated d dimer mean besides blood clot?

D-dimer: D-dimers can be elevated if the liver isn't functioning well or if there is any sort of clotting going on in the body, either following surgery or to things like dic. You need to see a hematologist to get an accurate diagnosis. ...Read more

D-dimer showed elevated , CT of lung showed no clot what else could this mean? I'm worried! what other test should I request to be done ?

D-dimer showed elevated , CT of lung showed no clot what else could this mean? I'm worried! what other test should I request to be done ?

How high?: No one knows where to put the cut-off for d-dimer. It's an inexpensive and radiation-free screen for pulmonary thromboembolus. When suspicious for pulmonary embolus, we set the "decision level" low, so that many people tested will be false-positives, as i take it you are. Hope you are feeling better; best wishes. ...Read more

I went to the ER with severe left arm and upper back pain the ER Dr said my D dimer was slightly elevated but CT scan was normal. What an this mean?

Follow up needed: D dimer and CT angiogram are used to help diagnose pulmonary embolism ( blood clot in lung). No test is foolproof, so if symptoms persist, follow up with your doctor is essential. Sever left arm and upper back pain are concerning symptoms and may signal heart disease. Best to see your doctor as soon as possible. ...Read more

Can having an elevated d dimer be dangerous?

Can having an elevated d dimer be dangerous?

Perhaps: 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. Elevations may suggest a clotting problem. ...Read more

Other than a clot, what else could cause an elevated d-dimer test? Mine was approx 270... I was told cut off was 230

Clinical context: D-dimer values near the edge of a reference range are difficult to interpret, and are meaningful only in the context of the big picture. There are false-positives. If a search for a thrombus / thromboembolus and for disseminated intravascular coagulation were non-revealing, perhaps you would do best simply to be thankful for good health. ...Read more

Can you have an elevated D-dimer (1.671) without thrombus? I have APS + SS, and on Xarelto 10 mg.

Yes: There are many causes of elevated D-dimer, other than clot. D-dimer test is good for excluding clot, if the test is negative, but a positive result does not equate to a clot and requires additional investigation. ...Read more

Is an elevated d dimer related to high blood pressure?

Is an elevated d dimer related to high blood pressure?

Not really: D dimer is a marker of clotting. Blood clots in the legs and lungs are associated with elevation. It will also go up with injuries and surgery.

Blood pressure may go up as a complication of a blood clot in the lungs or because of the injury or surgery, but elevated BP should not cause increase in d dimer, or vice versa. ...Read more

Can inflammation from a severe lupus flare cause an elevated d dimer of 1600? Crp over 200. Esr 50.

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. ...Read more

Is there a potential link between an elevated d-dimer level and a diagnosis of multiple myeloma? Note: I have an oncologist, just doing some extra research.

Is there a potential link between an elevated d-dimer level and a diagnosis of multiple myeloma? Note: I have an oncologist, just doing some extra research.

Potentially: As both multiple myeloma and several of the therapies utilized in this condition lead to increased risk of clots, and d dimer elevation is supportive of a clotting process. ...Read more

What other conditions, besides PE could cause an elevated d dimer (1326) and constricted breathing with pain when exhaling? CT (contrast dye) normal.

What other conditions, besides PE could cause an elevated d dimer (1326) and constricted breathing with pain when exhaling? CT (contrast dye) normal.

The D Dimer: testing is often "non-specific" and can be positive (eg advanced age, malignancy, and pregnancy HOWEVER along with the symptoms you describe DESPITE the negative CT with Contrast a PE (which has DISSOVED before causing INFARCTION (Death of lung tissue which shows up on CT/Contrast testing) is the MOST LIKELY DIAGNOSIS at your age (25)

I had an elevated D-dimer result of 464. I had an X-ray, CT and EKG done. All came back fine. What could cause this elevation and should I be worried?

I had an elevated D-dimer result of 464. I had an X-ray, CT and EKG done. All came back fine. What could cause this elevation and should I be worried?

Why all the tests?: I'm guessing you had chest pain and shortness of breath and they thought you had a blood clot to the lungs. The elevated d-dimmer indicates the presence of a clot but not location. Depending on how elevated your doc may start anti coagulation medication. If you are awake and online and under the care of a doctor there's probably not much to worry about. ...Read more

Could 3 small bruises cause an elevated d-dimer? Also, online info says vitamin C supplementation can affect PPT results. Would they be high or low?

Could 3 small bruises cause an elevated d-dimer? Also, online info says vitamin C supplementation can affect PPT results. Would they be high or low?

Labs: I'd be surprised if the d-dimer was up because of bruises, and would not discount a high value as part of the big picture just because you're been bruised. You know that many healthies have "elevated" this-or-that. People on megadose vitamin C may have extra oxalate in the blood that some folks suggest could bind the calcium reagent; this isn't something we actually worry about. ...Read more

What does a high d-dimer quant count mean?

Depends on disease: D-dimer is usually not requested unless there is a work up to do to establish the yes or no diagnosis of DVT or pe (clots in leg or arm) or dic in sepsis. It should not be used to make an unknown diagnosis as it can be elevated in many inflammatory conditions. In the above clots or dic if elevated it helps point to a yes diagnosis, then full work up still has to be done. It gives reason to proceed. ...Read more

If I have a negative D dimer, what does this mean?

D-dimer: D-dimer is tested in the blood when there is a concern for a blood clot. As blood clots in the body begin to breakdown, certain proteins are released, resulting in a positive D-Dimer test. A negative D-Dimer test is suggestive that a blood clot is not present. ...Read more

Please answer! what does a low d-dimer by high fibrinogen mean?

Clots coming ; going: D-dimer is increased with breakdown of clots to crosslinked fibrin. Fibrinogen forms fibrin whose fibers become crosslinked to form a clot. So high fibrinogen infers clot formation, not breakdown, so d-dimer is inferred to be low. ...Read more

Why is a d-dimer, quantitative test result of <0.27 mean? Why is that showing abnormal?

Normal finding: D-dimer is a breakdown product that is produced when blood clots are formed and broken down in the bloodstream. A low number is completely normal, even if the laboratory is reporting that it is below a normal range. This blood test is frequently used to rule out a blood clot in the leg or in the lung. A low number is very reassuring that no blood clot is present. ...Read more

What does it mean if you have a blood test done and the d-dimer is positive with a count of around 4.6?

What does it mean if you have a blood test done and the d-dimer is positive with a count of around 4.6?

Limited without more: 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. Therefore, a value of 4.6 means nothing. There are factors that can cause false readings. ...Read more

What could cause elevated d dimer besides blood clotting? I havent injured myself but my d dimer level is elevated and nothing was found in my chestCT

Many causes: Elevated concentrations of plasma D-dimer can be caused by many conditions to include arterial (stroke, atrial fib, etc) or venous blood clots (DVT), pulmonary embolism, infection (sepsis/ inflammatory response), normal pregnancy, pre/eclampsia, malignancy, surgery, tissue necrosis, congestive heart failure, liver disease, intravascular coagulation.

Is it possible for multiple sclerosis to cause d dimer blood test to always come back elevated?

D-dimer level .76 High.  INR test 1.1 High. Total Protein 8.6 HIGH. Diffuse fatty infiltration liver. What could this mean?

Need more info: Diffuse fatty infiltration can have many causes, common ones being fatty liver due to alcohol and fatty liver associated with obesity, metabolic syndrome and diabetes. It would require more information to settle the issue. However, if you are even slightly overweight, reduce you weight through diet and exercise, not easy, but essential. ...Read more
