blood galactose

Galactose is a type of hexose. This test is used to check for galactosemia. Galactosemia is due to a defect in galactose kinase or galactose-1-phosphate uridine transferase, which prevents the conversion and utilization of galactose, leading to an increase in galactose in blood and urine. Galactosemia is a hereditary deficient disease. 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: Contains no galactose. Positive: Lactating women and newborns sometimes have a small amount of galactose in their blood and urine. Congenital galactose metabolism disorders also contain a small amount of galactose. Tips: elevated serum galactose can also be seen after meals, emotional stress, the use of hormone therapy, etc., so these factors should be noted before the examination. Normal value Normally displayed as negative. Clinical significance Normal adult blood and urine contain no or only traces of galactose. Lactose women and newborns may have a small amount of galactose in their blood and urine. Patients with congenital galactose metabolism may develop galactose in the blood and urine. The index of hyperthyroidism increased, the galactose index of patients with hepatitis increased, and the index decreased after the disease was relieved. Positive results may be diseases: hyperthyroidism, hepatitis, galactosemia considerations in children (1) Reference values ​​of galactose in urine: neonatal <3.33 mmol/L; infant to adult (24 h) <0.08 mmol. (2) elevated serum galactose can also be seen after meals, emotional stress, the use of hormone therapy. Inspection process Take 0.5 ml of distilled water, 0.1 ml of serum, 0.2 ml of 0.15 mol/L cesium hydroxide, mix well, add 0.275 ml of 0.175 mol/L zinc sulfate, and mix and centrifuge to prepare 1/10 deproteinized blood filtrate. 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.
