What can cause my daughter to have high monocytes, eos, eos absolute, platelets and prothrombin time?

Check with doc: Isolated increases in monocytes and eosinophils are often normal, especially if the overall WBC is normal and the patient is not sick.

Decrease in prothrombin time can lead to what?

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?

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?

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 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?

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

What is the prothrombin time in a blood test?

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. This shoud be worked-up dr.'s office. ...Read more

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
