2 hours postprandial blood glucose (2HPG, PBG)

Normal people's blood sugar is relatively constant, and most of them fluctuate within a certain range after eating. The blood sugar concentration is increased due to eating, accompanied by increased insulin secretion. Blood glucose 2 hours after a meal is one of the main tests for the diagnosis of diabetes.

Normal value ≦ 7.8 mmol / L. Clinical significance 1. If the blood glucose concentration is 2, 8 mmol/L and <11, 1 mmol/L 2 h after meal, considering the abnormal glucose tolerance, a glucose tolerance test should be performed. 2, if the blood glucose concentration of 2h after meals, 11, 1mmol / L, combined with clinical diagnosis of diabetes. 3, diabetes control goals (Asia-Pacific type 2 diabetes policy group, July 2002) 2h postprandial blood glucose 4, 4 ~ 8, 0 is ideal control, ≦ 10mmol / L is well controlled, > 10mmol / L is poor control. Precautions 1, determination of fasting blood glucose, must be measured before the 8:00 in the morning, especially in patients treated with insulin, fasting blood must be in the morning before the usual injection of insulin, otherwise the measured blood sugar will increase and can not truly reflect The control of diabetes. 2, various stress conditions, blood sugar will also increase, such as mood fluctuations, insomnia, fever, fatigue, etc. can affect blood sugar, so should go to the hospital to avoid strenuous exercise. 3.

Inspection process Glucose oxidase (GOD) method: Take a number of 16mm × 100mm test tubes, mix, set in a 37 ° C water bath, keep warm for 15 min, use spectrophotometer wavelength 505nm, cuvette light path 1.0cm, use blank tube to adjust the colorimetric color, read the standard tube and determine The tube absorbs light. Not suitable for the crowd Those without examination indications should not be tested. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
