How long should bruising last after having a blood test taken and why have I developed bruising all around my elbow on the same arm and behind the knee of the same side of the body?

How long should bruising last after having a blood test taken and why have I developed bruising all around my elbow on the same arm and behind the knee of the same side of the body?

See primary M.D.: Bruising at puncture sight from needle is very common and clears out in about a week. However having bleeding around elbow and knee is bothersome, You should go and see your primary doctor. After checking you out, he may need to do some more blood tests to rule out any bleeding disorder.

Why does the skin on your arm around the area blood is taken from bruise after a blood test?

Why does the skin on your arm around the area blood is taken from bruise after a blood test?

Bruise: The blood vessel is punctured when blood is withdrawn during a blood test. If the vessel is not compressed long enough, blood will leak out of the vessel giving a bruise. Holding direct pressure with a cotton ball for 10 or 15 minutes is usually enough. However if a person is on platlet inhibitors such as asprin longer might be necessary.

Got a really bad bruise after blood test, help?

Got a really bad bruise after blood test, help?

See below: A small number of normal people get a bruise after blood draw and vast majority of these resolve without any serious consequences. Is the bruise stable? If it is growing, contact your doctor. If it is not growing, has no redness beyond the bruise and is not painful, you may leave it alone and it will resolve. It may go through a change of colors like brown, greenish-blue and yellow.

Been bruising for awhile now hermatologist did all blood test and they are all normal can stress be a cause?

? Bruising?: If there has been no trauma you have to find out why you are bruising. There are screening tests for numbers of cells but then there are questions about the functionality of the cells. It is NOT normal to be bruising frequently. When a doctor says everything is normal in that situation he is saying everything that I looked for is OK and now you how to look further. Go to Univ. Med. Center near u.

I have been finding random bruises all over my body, some have been big. I had blood test and everything was fine. But I feel like something is wrong?

Depends on test: Some people bruise easier than others, but you should be evaluated to make sure your blood clots normally. If they checked your liver function along with a PTT and a PT/INR and those all came back normal, THEN I'd be less concerned, but you should work with your doctor to find out what is happening until your doctor says he/she believes everything is fine and you need no further testing.

Bruises in legs CBC blood test normal, s.g.p.t normal, s.g.o.t normal what is the cause of these bruises?

Bruises in legs CBC blood test normal, s.g.p.t normal, s.g.o.t normal what is the cause of these bruises?

Bruises: Hi, it seems your CBC and liver function test are normal but how's your PT/PTT (coagulation tests), why are you taking Leflunomide and Sulfasalazine, inflammatory bowel dx? Leflunomide can cause low platelet which could lead to easy bruising, R u taking any Aspirin, Ibuprofen? Also you are on Steroid which can make the skin thin and causes rupture of small vessels under skin with slight trauma.

I had a blood test a week ago that left a small bruise, which is now large/dark purple and spreading up arm. Could there be something wrong?

I had a blood test a week ago that left a small bruise, which is now large/dark purple and spreading up arm. Could there be something wrong?

Yes, if the arm is hot: To touch, and you have swelling, and see streaks of bruising going up the arm. Then you have to go immediately in the ER. If it is not hot to the touch, and no swelling or pain, then you need to call your doctor as soon as possible to be seen by her/him, and notify the lab that you are experiencing this too. That has to be documented by the lab manager. Blood thinners or low platelets can do this2

Likely OK,,,: It usually takes about 1-2 weeks for an injury, even a needle stick, to heal fully. If you are still worried, see your doctor for an exam and the results of your blood test. Good luck.

I always get arm pain after IV or blood test sometimes bruise regardless of where the needle was. Should I be concerned?

I always get arm pain after IV or blood test sometimes bruise regardless of where the needle was. Should I be concerned?

It depends: Whether you should be concerned depends on how big the bruise is and whether you have any problems with your blood clotting factors. If you are worried you could get your blood checked to make sure you don't have a problem that would you have a tendency towards bleeding easily.

1yr old has bruise on leg bloods came back platlelet 90 neutrophils 0.7 why are the requesting second blood test?

1yr old has bruise on leg bloods came back platlelet 90 neutrophils 0.7 why are the requesting second blood test?

Confirmation: The numbers you give are not very helpful but platelets of 90 (thousand) are on the low side. What. 7 neuts refers to is confusing. You repeat a test to see if the initial test was wrong, the levels change or to define the problem more clearly. Low platelets could be a technical glitch, a problem with production or excessive destruction. Further testing narrows your search.

Had blood test wk ago. Large bruise came up on forearm + elbow, now have tender limp inside of elbow where I guess blood was taken. Do I need the dr?

Hematoma: Some of the blood apparently escaped from the vein into the surrounding tissue when blood was withdrawn for testing. This happens sometimes but should be small and should slowly resolve (it first looks like a bluish bruise then turns brownish and finally over few days it becomes firm and eventually resolves. Call dr if it becomes infected (turns red, hot and painful)

Not often but sometimes I wake up with random bruising and have no trauma or injury to the part of my body that has been bruised. Blood test??

Ideas: History and physical exam. Taking meds? Platelet count as part of the CBC, pro time, partial thromboplastin time. Basic chemistries. Tourniquet test and bleeding time are not obsolete. Antinuclear antibody screen. If any suspicion of vasculitis, more labs.

Coagulation studies: Make sure that you have had the appropriate coagulation studies performed. Do you have family history of easy bruising? If your coagulation studies are normal, than aspirin or even ibuprofen usage can cause ecchymosis (bruising). If you aren't taking any medications that cause prolonged bleeding time and all coagulation a studies are normal, then be assured that you are fine and healthy.
