Can I test at any age for DVT genetic test?

Can I test at any age for DVT genetic test?

Yes: I presume you are referring to a predisposition for clotting. (hypercoaguability). Since these protein abnormalities are inherited and present from birth, they can be assessed at any age. ...Read more

Genetic Testing (Definition)

Prenatal testing for genetic problems may be done before or after conception. Testing for spina bifida or Down syndrome is done after a pregnancy is established. Besides the couples listed above, counseling and diagnosis are also recommended for mothers over the age of 35, and those who have received abnormal screening test results, such as alpha-fetoprotein (AFP). For more information about the alpha-fetoprotein test, and when and why you might have it, see alpha-fetoprotein. For those who may be at risk, genetic counseling and prenatal diagnosis are used to help ...Read more

Are there alternative treatments for people that have DVT quite often and have a genetic disposition?

Are there alternative treatments for people that have DVT quite often and have a genetic disposition?

RECURRENT DVT: If you have recurrent DVT and a genetic predisposition to develop DVT then your only option would be indefinite oral anticoagulation. This used to be a major problem in the past because the only oral anticoagulant was coumadin which required frequent blood testing. Now there are many alternatives which do not require frequent blood testing and work efficiently. ...Read more

My son, 35, avid walker, no genetic factors, no drugs, never sat down, didn't smoke, drink, died of a pulmonary thromboembolism caused by dvt?

My son, 35, avid walker, no genetic factors, no drugs, never sat down, didn't smoke, drink, died of a pulmonary thromboembolism caused by dvt?

I'm so sorry: My heart goes out to you--it certainly sounds like your son didn't have DVT risk factors, however pulmonary emboli can happen and almost anyone. Genetic factors can play a role. You may want to talk to a henatologist (blood doctor) about possible clotting problems in your family. ...Read more

My leg been hurting for 3 weeks from my calf up ..... 2 ultrasounds came back negative for dvt . Im worried are these test pretty accurate? Help

My leg been hurting for 3 weeks from my calf up ..... 2 ultrasounds came back negative for dvt . Im worried are these test pretty accurate? Help

They are: They are highly accurate for detecting a blood clot in the leg, 97% accurate by most studies which is excellent. There are many causes of leg pain, and in fact, a clot typically won't cause pain unless the vessel becomes inflamed. A clot in the leg most often manifests as new significant swelling of one leg relative to the other, often after a period of immobilization such as a long flight. ...Read more

What blood tests detect a clot (dvt)?

Blood tests for clot: There are no specific blood tests that will be definitive to prove a clot exists. Ultrasound, CT andMR are the diagnostic modalities to prove a clot. D-dimer is a blood test that can be used to identify clot formation but it is very non specific. If negative there is good evidence that a clot does not exist but d-dimer can be positive for many reasons not related to a clot. ...Read more

Do I need tests for DVT if hot red leg?

Do I need tests for DVT if hot red leg?

Very possibly: It depends on whether you were doing anything that might have made it more likely to have a blood clot, your family history, and whether you have any risk factors for blood clots. Also, is there anything else it could be. If, with all that information and the appearance of your leg, it looks like you are at risk, then the doctor will test you to see if you have a dvt. Bottom line: see a doctor. ...Read more

How accurate is capillary refill test for pad or dvt?

How accurate is capillary refill test for pad or dvt?

Not the best.: Capillary refill is essentially an observation of how long it takes for blood to return into small vessels usually in the nail beds or feet. It is not accurate and it is not used for dvt. It is observed in pad. There are much more specific, informative and diagnostic tests for both DVT and PVD such as duplex scans and abi's and even cta's. ...Read more

Just read that dvts can be caused by hyper coagulation in the body due to cancer. What blood tests detect cancer? What type of cancer can cause clots?

Had DVT before and had an another test last week which my d dimer result came back at 422 but scan of left leg was clear what does this mean?

D-dimer: D-Dimer is extremely sensitive but highly non-specific. In other words, it will be elevated in all cases of clot but in most instances, it's a false alarm. Your experience is typical. ...Read more

Got swelling left legon- off last trimester to 8 mon post baby. Got test done thrice for DVT came negative — baby is 16mons got swelling in leg now?

Possible: Possible to get swelling around this time due to venous congestion, cardiovascular changes, or vein compression (usually later). If swelling gets worse do keep an eye on it and get tested to exclude dvt. ...Read more

F24,start taking natazia, on day 2 done d-dimmer 0.45(lab norm<0.5), dont have any risks of dvt or PE.need to be concerned?(test not priscribed by doc)

By definition,: Use of oral contraceptives, particularly those containing an estrogen, is a risk factor for DVT/P.E. In a healthy young female who doesn't smoke, the risk is very low. However, a family history of clotting disorders, prolonged inactivity, varicose veins and leg fracture can increase the baseline risk. Getting a test done without a doctor's involvement carries some risk as well Dr. Anne. ...Read more

What tests sholuld I have if I have a family history of dvts?

Depends: Testing for you would be based upon the genetic abnormality detected in your affected family member. If your family has been tested and no abnormality was found you don't need further testing. If no testing has been done on your family you should ask your doc to evaluate the situation and see if it makes sense to test you. ...Read more

Hi I have recently had a DVT and PE and during tests was found to have a high heart rate....120-130bpm. Further tests showed I have a complete LBBB, u?

It is physiological: to have an elevated heart rate in the setting of PE. LBBB is also reasonably common and in the absence of symptoms (passing out) nothing need be done about it. In addition it is possible that the high heart rate or even the presence of a PE itself could result in a transient LBBB which will resolve as your PE resolves. ...Read more

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Ultrasound for DVT: Ultrasound for lower extremity DVT's have great sensitivity and specificity meaning they are very good at picking up a DVT. There is a 2% chance of somebody having a negative scan and having one found 1 week later according to studies, although repeating it is often done if there is strong suspicion. D-dimer values are not universal so that may be high but values can be high in a lot of disease. ...Read more

My leg turns redish purple while sitting or standing, but fine while lying. Tingles too. Blood test says no DVT or clot. What else causes this?

My leg turns redish purple while sitting or standing, but fine while lying. Tingles too. Blood test says no DVT or clot. What else causes this?

Likely stasis: There are signs of congestion.
If pulses and inflow are good-normal. Then cyanosis edema are signs of congestion.
Can be from heart failure, tricuspid valve, or more likely venous insufficiency without a current clot.
On the left occasionally the vein is compressed and can lead to congestion.
See a vascular surgeon and get an on site opinion and followup. ...Read more

Does a negative d dimer rule out a DVT and PE? Been having chest and calf pain, but ER Dr said that I didn't need any more tests since it was negative

Does a negative d dimer rule out a DVT and PE? Been having chest and calf pain, but ER Dr said that I didn't need any more tests since it was negative

99.5% of time, nothi: The D-Dimer, if negative, does a fairly good job of ruling out DVT/PE, but isn't absolute (no test is absolute 4 everything). 99.5% of the time a neg D-Dimer means no DVT/PE. (But 1 out of 200+ times it could be falsely reassuring). Not knowing ur specific condition, it's reasonable to look elsewhere 4 the cause of ur symptoms (chest, calf pain) w/ other tests perhaps. TTY regular doc about it. ...Read more

Pos. Ovulation test on jan 20-23rd.  Had brown discharge on the feb 5th-9th instead of period.  I am a renal txp pt and b.T. For dvt. Could i be preg?

I am wondering if: The brown discharge was a light period. Old blood often looks brown. The 5th would have been 14 days after you ovulated. If you are uncertain, go ahead and take a home pregnancy test now. Take care. ...Read more
