Hemoglobin Thermal Instability Test

The hemoglobin heat instability test is a test for heating the blood to check the thermal stability of hemoglobin and can be used to diagnose unstable hemoglobinopathy. This test is suitable for people who have repeated hemolysis and have a source of infection. Avoid taking oxidizing drugs before testing. The precipitated hemoglobin was less than 5% in the heat stability test. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: Generally it is normal. Positive: Prompt for unstable hemoglobinopathy. Tips: Avoid taking oxidizing drugs before checking. Normal value The hemoglobin precipitated in the heat stability test was less than 5% and was negative. Clinical significance Abnormal result Freshly dissolved blood was taken. After heating at 50 ° C for 2 hours, the hemoglobin was precipitated by more than 5%, suggesting unstable hemoglobin disease. The people who need to be examined have weak, weak, sleepy, pale skin, mucous membranes, palpitations, dizziness, headache, tinnitus, vertigo, inattention, and lethargy. Positive results may be diseases: unstable hemoglobin disease, hereditary elliptic polycythemia considerations Contraindications before examination: Avoid taking oxidizing drugs. Inspection process Freshly dissolved blood was taken, and after heating at 50 ° C for 2 hours, the amount of hemoglobin precipitated was examined. Not suitable for the crowd Hemolysis repeatedly, people with infections. 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.
