blood fructose

The sugar that enters the human body from the digestive tract, in addition to glucose, there are a small amount of other hexoses, such as sugar, galactose, and mannose. After being absorbed by the sugar, it can be transformed into the catabolism of sugar in the body to provide energy or synthetic glycogen for storage. When certain enzymes in the human body are deficient or certain diseases, the metabolism of fructose can be abnormal, so that fructose can not be transformed and utilized. Determination of fructose in blood and urine can be elevated. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Common in hypoglycemia or a normal physiological response. Normal value: Serum: fasting: 0-0.56mmol/L Serve sugar: 30min: 0.83-1.38mmol/L Serve sugar: 120min: 0-0.56mmol/L Above normal: Common in fruit diabetes (caused by fructose kinase deficiency), hereditary fructose intolerance, fructose-1 and other diseases. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value Serum: fasting: 0 ~ 0.56mmol / L. Serve sugar: 30min: 0.83 ~ 1.38mmol / L. Serve sugar: 120min: 0 ~ 0.56mmol / L. Clinical significance After taking fructose for 2 hours, the increase in blood and urine fructose was seen in fructoseuria (caused by fructose kinase deficiency), hereditary fructose intolerance, and fructose-1,6-diphosphatase deficiency. High results may be diseases: pediatric hereditary fructose intolerance considerations (1) Patients with fructose diabetes have normal blood sugar: blood sugar is reduced in patients with hereditary fructose intolerance. (2) The reference value of fructose in urine is 0.17~0.36mmol/L. Inspection process Subjects were venously collected and assayed in time for serum separation. The color principle is determined by the same year. 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.
