  2. Prothrombin time - Wikipedia

    en.wikipedia.org/wiki/Prothrombin_time

    The prothrombin time (PT) – along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation. This blood test is also called protime INR and PT/INR.

    en.wikipedia.org/wiki/Vitamin_K_reaction

    Additional risk factors include 1) infants who never got a vitamin K shot at birth, even more so if they were solely breastfed, 2) infants who had mothers taking medications to treat seizures since these affect how the body uses vitamin K, 3) infants with diarrhea, cystic fibrosis, and celiac disease because this makes it hard to absorb ...

  4. Anticoagulant - Wikipedia

    en.wikipedia.org/wiki/Anticoagulant

    The INR test measures the time it takes for a clot to form in a blood sample relative to a standard. An INR value of 1 indicates a level of coagulation equivalent to that of an average patient not taking warfarin, and values greater than 1 indicate a longer clotting time and, thus, a longer bleeding time. Assessing bleeding risk

  5. Vitamin K - Wikipedia

    en.wikipedia.org/wiki/Vitamin_K

    Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]

  6. Coagulation - Wikipedia

    en.wikipedia.org/wiki/Coagulation

    PT results are often reported as ratio (INR value) to monitor dosing of oral anticoagulants such as warfarin. [50] The quantitative and qualitative screening of fibrinogen is measured by the thrombin clotting time (TCT). Measurement of the exact amount of fibrinogen present in the blood is generally done using the Clauss fibrinogen assay. [47]

    Food poisoning symptoms can vary widely in severity, as can the length of time one feels sick. Many people feel better after several hours, but it is not uncommon for symptoms to persist for 24 to ...

  8. Vitamin K deficiency - Wikipedia

    en.wikipedia.org/wiki/Vitamin_K_deficiency

    Symptoms include bruising, [2] petechiae, [2] [3] and haematoma.. Vitamin K is changed to its active form in the liver by the enzyme Vitamin K epoxide reductase.Activated vitamin K is then used to gamma carboxylate (and thus activate) certain enzymes involved in coagulation: Factors II, VII, IX, X, and protein C and protein S.

  9. Liver function tests - Wikipedia

    en.wikipedia.org/wiki/Liver_function_tests

    In patients with liver disease, international normalized ratio (INR) can be used as a marker of liver synthetic function as it includes factor VII, which has the shortest half life (2–6 hours) of all coagulation factors measured in INR. An elevated INR in patients with liver disease, however, does not necessarily mean the patient has a ...
