My prothrombin time INR is 1.5 is it dangerous?

My prothrombin time INR is 1.5 is it dangerous?

Why is it 1.5?: You probably mean inr of 1.5 (normal prothrombin time is about 12 seconds). It is not dangerous by itself but why is your inr prolonged? The disease process causing this prolongation may be dangerous, e.G, liver disease, malabsorption causing vitamin deficiency etc. Please consult your doctor to determine the cause and treat the underlying process. ...Read more

Prothrombin time - 15.8 sec and INR - 1.2 what could be the reason for increase? and i am on B12 inj now for a week, does it affect them.hvy periods

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your prolonged PT is not likely to be the cause of heavy periods.There is no relation between B12 and prolonged PT either. Given the health issues you have, it is something best discussed with your doctor who has more information. ...Read more

B12 inj(500mcg) for a week, does it increase clotting time,bleeding time?does it affect prothrombin time & INR? what supplements needed on B12 therapy

B12: B12 itself will not influence clotting or bleeding. However, as anemia corrects, blood clotting improves. Platelet count can raise as B12 improves marrow. Take folic acid, other B vitamins, and get potassium from food. ...Read more

My prothrombin time is INR 1.3 with normal aptt and platelet counts. Do I have liver failure? Normal ast, alt, alp and bilirubin. Burns right stomach

My prothrombin time is INR 1.3 with normal aptt and platelet counts. Do I have liver failure? Normal ast, alt, alp and bilirubin. Burns right stomach

Probably not: The slight elevation in the inr with normal labs for the rest of your liver functions suggests you don't have liver disease. The burning could be coming from an ulcer, or gastritis, or esophagitis. The body doesn't do a good job of localizing pain coming from the internal organs, so where you feel the pain may not be where it is.. Follow up with your doctor to check out different causes. ...Read more

What does it mean when my prothrombin time blood test is high, compared to normal or low?

What does it mean when my prothrombin time blood test is high, compared to normal or low?

Can mean Vit K low.: If prothrombin time blood test is high, without other high levels, it can mean a vitamin k deficiency or warfarin use. Vitamin k helps in the function and viability of factors ii, vii, ix, and x and these affect prothrombin time. If there are other levels altered, it could be a factor v, or x deficiency, disseminated intravascular coagulation (dic), or liver failure. See your doctor to be sure. ...Read more

What is thrombocytopenia and how is a prothrombin time test used?

What is thrombocytopenia and how is a prothrombin time test used?

Blood clotting: Thrombocytopenia means low level of blood plateletes. Prothrombin time is a test for extrinsic coagulation pathway that is initiated with factor vii. Vitamin k deficiency or use of Coumadin (warfarin) or liver function deficiency will prolong the prothrombin time, while several blood clotting diseases that affect intrinsic coagulation such as von willibrand or hemophila will not affect prothrombin time. ...Read more

What types of drugs an foods interfere with the coagulation test of prothrombin time?

What types of drugs an foods interfere with the coagulation test of prothrombin time?

Depends on : Circumstances. In a normal person, usual drugs and foods do not affect pt measurably. In patients on warfarin, foods both prolong pt, e.g., grapefruit, or shorten it, e.g., green leafy vegetables. Many drugs affect pt, e.g., birth control pills, isoniazid, anti-fungals, antibiotics, and many other drugs metabolized through cytochrome p450 system, and barbiturates and alcohol. ...Read more

Repeat test.: A shortened clotting time that does not appear to reflect technical error has been associated with an increased risk of thrombosis, recurrent thrombosis, recurrent miscarriage, or bleeding, and may increase the risk of thrombosis associated with other common thrombotic risk factors (eg, factor v leiden, obesity, increased levels of d-dimer). ...Read more

How can I get a normal range of prothrombin time?

12 Seconds, but INR: Normal prothrombin time varies a from lab to lab; the average value is about 12 seconds. To compensate for the variability, the ratio of each lab's normal to the patient value is reported as international normalized ratio (inr) and an inr of 1.0 is normal. ...Read more

What does an abnormal prothrombin time test mean for you?

What does an abnormal prothrombin time test mean for you?

Abnormal clotting : An abnormal prothrombin time means that there is something wrong with your blood's ability to form clots and prevent bleeding. There are many conditions that result in such an abnormality, and you need to have your doctor figure out what the problem is based on other test findings and your symptoms. Sometimes you'll need a hematologist to consult if there is a chance of a serious bleeding problem. ...Read more

What is the prothrombin time in a blood test?

Measures clot factor: This is a test that measures clotting factor activity. All these factors are synthesized in the liver, except factor viii, so this is also a check on the capability of the liver as well. If this is high, it can be from a deficiency or incabability of the factors or a liver failure issue, like cirrhosis, or a vitamin k deficiency from fat malabsorption.
