what the risks are factor v assay, blood test to measure the activity of factor v, the substances involved in coagulation, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, vein to swell, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, in infants, young children, area is cleansed, antiseptic, punctured, a sharp needle, a lancet, blood collected, pipette, small glass tube, on a slide, onto a test strip, into a small container, a bandage applied, puncture site, any bleeding, , no special preparation needed, adults, infants, children, procedure depends on child's age, previous experience, level of trust, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the needle is inserted to draw blood, feel moderate pain, a prick, stinging sensation, some throbbing, this test, detect the specific cause of, excessive bleeding, decreased blood clotting, value, 50-200%, the laboratory control, reference value, decreased factor v activity associated, congenital deficiency of factor v, disseminated intravascular coagulation, dic, liver disease, cirrhosis, primary fibrinolysis, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, often performed on people, bleeding problems, risk of, excessive bleeding is slightly greater than, bleeding problems, coagulation, blood clotting, a sequence of reactions involving several proteins known, coagulation factors, of these factors have other names, factor i, fibrinogen, factor ii is prothrombin, factor xii is hageman factor, liver produces these proteins, secretes them, blood, vitamin k is important to blood clotting, body converts it into prothrombin, take warfarin to keep blood from clotting, warfarin inhibits prothrombin, interrupting the clotting cascade, the link between vitamin k, prothrombin, people who take warfarin need to have consistent levels of vitamin k in diet, coagulation begins, the coagulation factors contact damaged tissue, each factor reaction triggers the next reaction, cascade, final product, the coagulation cascade, blood clot, substances that inhibit, turn off the action, the coagulation factors, activated, the coagulation factors, substances function more slowly, over a longer period of time, than the coagulation factors, allows a clot to form, stopping the bleeding, after enough time has passed, the tissue to heal, clot is dissolved, blood flow restored, most important coagulation inhibitor is antithrombin iii, veins, arteries vary in size, obtaining a blood sample.
