clotting time การใช้

• Normal value of clotting time is 8 to 15 minutes.
• There are various methods for determining the clotting time, the most common being the capillary tube method.
• The quantitative and qualitative screening of fibrinogen is measured by the thrombin clotting time ( TCT ).
• The heart rate and blood pressure go up, the blood gets thicker, and its clotting time gets faster.
• The man had a long clotting time, but he had undergone successful surgery in the past without suffering from major bleeding.
• Hemoglobin ( the protein in red blood cells that transports oxygen to body tissue ) is measured and clotting time calculated.
• Mutations in factor XII have been associated with an asymptomatic prolongation in the clotting time and possibly a tendency toward thrombophlebitis.
• And you can often catch little problems, like a worrisome trend in clotting time or blood sugar levels, before they become big ones.
• Partial thromboplastin time should not be confused with prothrombin time, or PT, which measures blood clotting time through a different pathway of the coagulation cascade.
• If a clotting inhibitor such as a lupus anticoagulant is present, the inhibitor will interact with the normal pooled plasma and the clotting time will remain abnormal.
• The venom is diluted to give a clotting time of 23 to 27 seconds and the phospholipid is reduced to make the test extremely sensitive to phospholipid.
• A test performed after the mixture is incubated for 1 to 2 hours at 37癈 will show significant prolongation over the clotting time obtained after immediate mixing.
• Other features of fat malabsorption may also occur such as reduced bone density, difficulty with vision under low light levels, bleeding, bruising and slow blood clotting times.
• The clotting time is based on a relative scale and requires a baseline value for a point of comparison due to inconsistencies between the source and formulation of the activator being used.
• High doses of vitamin E may produce headaches, tiredness, double vision, and diarrhea in humans and doses higher than 800 mg may increase blood clotting time, especially for people on blood thinners.
• Five minutes after the bolus dose has been administered, an activating clotting time ( ACT ) should be performed and an additional bolus of 0.3 mg / kg should be given if needed.
• If the mixing test indicates an inhibitor, diagnosis of a lupus anticoagulant is then confirmed with phospholipid-sensitive functional clotting testing, such as the dilute Russell's viper venom time, or the Kaolin clotting time.
• Clotting time measurements can be affected by other drugs that such as Warfarin, aprotinin and GPIIb / IIIa inhibitors and may also be affected by physical perturbations to the body such as hypothermia, hypervolemia or hypovolemia.
• Even if that should happen in Bradley's case _ which would mean that he'd have to have his clotting time monitored and perhaps modify his diet _ Salem still didn't think that should disqualify him from serving as president.
• Furthermore, in 97 % of all cases the blood clotting time was prolonged ( more than 12 minutes ), 41 % had bleeding ( usually from the gums ), 32 % had local blistering and 9 % had necrosis.
