In addition to glucose, the sugar excreted from the body includes lactose, fructose, galactose, and sucrose. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: elevated serum galactose can also be seen after meals, emotional stress, the use of hormone therapy, etc., so the examination should be fasting. Normal value The enzymatic method was <14.6 μmol/L. Clinical significance Raise pregnant and lactating women. High results may be diseases: thyroid hormone resistance syndrome considerations (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 Rate method determination (taking a semi-automatic analyzer as an example): 1 main parameters: Coefficient 8.2. Incubation time 30s. Monitoring time is 60s. The wavelength is 340 nm. The sample volume was 0.5 ml. The temperature is 37 °C. 2 Loading: 1000 μl of pre-warming enzyme mixing reagent at 37 ° C, adding 20 μl of serum, and immediately inhaling an automatic analyzer to monitor the rate of increase in absorbance (ΔA/min). Not suitable for the crowd No taboos. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
