Plasma Viper Venom Phospholipid Time Determination

The time of plasma viper phosphatidylcholine is determined by adding venom to plasma to check the clotting time and to diagnose plasma factors. The people who need to be examined have weak, weak, sleepy, pale skin, mucous membranes, palpitations, dizziness, headache, tinnitus, vertigo, inattention, and lethargy. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat too greasy, high-protein foods the day before, and avoid heavy drinking. Normal value Plasma coagulation method is 8.3 to 10.7 s. Clinical significance Abnormal result 1. Both RVVCT and RVVRT prolonged the lack of factor X. 2. RVVCT is normal and RVVRT prolongs the lack of platelet factor III. 3, RVVCT and RVVRT are normal and PT prolongation lacks factor VII. 4. RVVCT prolongs congenital or acquired fibrinogen prothrombin, factor V and X deficiency. The people who need to be examined have weak, weak, sleepy, pale skin, mucous membranes, palpitations, dizziness, headache, tinnitus, vertigo, inattention, and lethargy. High results may be diseases: hereditary prothrombin deficiency, hereditary antithrombin III deficiency precautions Taboo before the test: Do not eat too greasy, high-protein foods the day before the test, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should fast. Requirements for examination: When taking blood, you should relax your mind to avoid the contraction of blood vessels caused by fear and increase the difficulty of blood collection. The amount of cerebral phospholipids affects the clotting time. When the amount of cephalin is large, the clotting time is shortened. After repeated practice, the amount of cephalin is set to 10 μl (1:1000 dilution). Inspection process 0.1 mg/ml anticoagulant protein 0.1 ml in vitro (the control group was physiological saline), and mixed plasma 4, 6, and 8 prepared with 30 parts of normal human plasma were added, and the ratio was set to 1:40, 1:60. 1: 803 different dilution concentrations, 50 μl per dilution, and then performed on a fully automated blood coagulation apparatus. Not suitable for the crowd 1. Patients taking drugs such as oxidative drugs and steroid hormones may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
