beam arm test

The beam arm test is when the capillary wall structure and function, the number and quality of platelets are defective, or the vitamin C and P deficiency in the body, or the blood vessels are damaged by physicochemical and microbial factors, the integrity of the capillary wall will be destroyed and its brittleness. Increased permeability, increased new bleeding points, and thus positive beam arm test. Basic Information Specialist classification: skin examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Capillary defect disease. Tips: Do not eat too greasy, high-protein foods the day before, and avoid heavy drinking. Normal value The test was negative, that is, the normal new bleeding point was below 10. Clinical significance Abnormal result The test was positive, that is, more than 10 new bleeding points. Can be seen in thrombocytopenic purpura, scurvy caused by vitamin C deficiency, due to excessive capillary fragility, beam arm test will also be positive. In patients with clotting factor deficiency, the beam arm test was negative. Therefore, the beam arm test has certain help in the differential diagnosis of hemorrhagic diseases. People who need to be examined are suspected of having a blood disease. Positive results may be diseases: immune thrombocytopenic purpura in the elderly, secondary immune thrombocytopenic purpura in children, simple purpura, pediatric idiopathic thrombocytopenic purpura 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 inspection: Relax muscles during examination. Inspection process 4cm in the elbow bend of the forearm, draw a circle with a diameter of 5cm, use the sphygmomanometer cuff to bundle the upper arm, first measure the blood pressure, then keep the blood pressure between systolic and diastolic pressure for 8 minutes, then lift Pressure, after the skin color returns to normal, count the number of new bleeding points in the circle. Not suitable for the crowd No taboos. Adverse reactions and risks Subcutaneous hemorrhage: subcutaneous hemorrhage due to less than 5 minutes of compression time or blood draw technique.
