serum transferrin

Transferrin is a beta globulin that binds to and transports iron in serum. It can be determined by immunoturbidimetry, immunodiffusion, enzyme immunoassay and radioimmunoassay. Increased in iron deficiency anemia, acute hepatitis, acute inflammation, oral contraceptives, late pregnancy. Reduced in nephrotic syndrome, cirrhosis, malignant tumors, hemolytic anemia, malnutrition. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. Normal value The immunoturbidimetric method was 28.6 to 51.9 μmol/Lv. Clinical significance Serum transferrin assay can reflect a variety of diseases such as iron deficiency anemia. 1, the test value is high: seen in iron deficiency anemia, acute hepatitis, acute inflammation, oral contraceptives, late pregnancy. 2, the test value is low: seen in nephrotic syndrome, cirrhosis, malignant tumors, hemolytic anemia, malnutrition. Low results may be diseases: iron deficiency anemia, nutritional metabolic disorders, high results may be diseases: small cell hypochromic anemia considerations First, the precautions before blood draw 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2, after the 8 o'clock in the evening before the physical examination, should be fasted, so as not to affect the detection of the second sky abdominal blood glucose and other indicators. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Second, should pay attention after blood draw 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient: each person's clotting time is different, and some people need a little longer to coagulate. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process Subjects were venously collected and assayed in time for serum separation. It was then determined by immunoturbidimetry. 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. Risk of infection: If you use an unclean needle, you may be at risk of infection.
