isopropyl alcohol test

The stability of unstable hemoglobin in the solvent isopropanol decreased, and it was observed whether turbidity appeared and whether unstable hemoglobin was present. This test is used to reflect the abnormality of globin synthesis. When there is unstable hemoglobin, turbidity often occurs at 5 min, and a villous precipitate begins to appear at 20 min. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: The temperature should not exceed 37 °C. Normal value Normally negative. Clinical significance When there is unstable hemoglobin, turbidity often occurs at 5 min, and a villous precipitate begins to appear at 20 min. 1. A sample found in hemoglobin F, E, and H content exceeding 4%. 2, seen in some globin-producing anemia. 3, seen in patients with G-6-PD deficiency. Positive results may be diseases: pediatric alpha-thalassemia, pediatric globin-forming anemia, hemolytic anemia considerations When measuring, the temperature should not exceed 37 ° C, otherwise false positives will occur. The examination process takes an appropriate amount of hemoglobin and is sent for inspection. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., 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.
