How to check whether the blood sugar is high or not on the whole blood report form

The blood glucose level in the whole blood report is mainly determined by indicators such as fasting blood glucose, postprandial blood glucose, and glycated hemoglobin. Abnormal blood glucose may be caused by factors such as insulin resistance, improper diet, and pancreatic disease.

1. Fasting blood glucose:

Fasting blood glucose is a key indicator for the diagnosis of diabetes, and the normal value is 3.9-6.1mmol/L. If fasting blood glucose ≥ 7.0mmol/L, it may indicate diabetes, and 6.1-6.9mmol/L belongs to impaired fasting blood glucose. Before testing, it is necessary to maintain a fasting state for at least 8 hours to avoid vigorous exercise or emotional fluctuations that may affect the results.

2. Postprandial blood glucose:

2-hour postprandial blood glucose reflects glucose metabolism ability, and the normal value should be<7.8mmol/L. When it reaches 7.8-11.0mmol/L, it means abnormal glucose tolerance, and when it exceeds 11.1mmol/L, it is necessary to be alert to diabetes. The testing should start counting from the first bite taken, during which smoking or additional eating is prohibited.

3. Glycated hemoglobin:

Glycated hemoglobin HbA1c reflects the average blood glucose level in the past 2-3 months, with a normal range of 4% -6%. If the result is ≥ 6.5%, it can help diagnose diabetes, and 5.7% -6.4% indicates pre diabetes. This indicator is not affected by short-term diet or exercise, but anemia patients may experience pseudo underestimation.

4. Random blood glucose:

diabetes can be diagnosed when random blood glucose ≥ 11.1 mmol/L is accompanied by polydipsia and polyuria. This indicator has reference value in emergency situations, but stress hyperglycemia interference needs to be excluded. There is no time limit for eating during testing, and it is necessary to make a comprehensive judgment based on other indicators.

5. Blood glucose fluctuations:

Daily blood glucose fluctuations exceeding 4.4mmol/L may increase the risk of vascular damage. Dynamic blood glucose monitoring can detect hidden hyperglycemia, especially suitable for individuals with normal fasting blood glucose but metabolic syndrome characteristics such as obesity and hypertension.

It is recommended that individuals with abnormal blood sugar levels monitor and record data regularly, with a daily intake of 200-300 grams of staple foods, and prioritize low glycemic index foods such as oats and brown rice. Perform 150 minutes of moderate intensity aerobic exercise per week, such as brisk walking and swimming. Avoid staying up late and feeling emotionally tense, and control simultaneously when combined with hypertension or hyperlipidemia. When typical symptoms such as blurred vision and unhealed wounds occur, timely medical attention should be sought for a follow-up OGTT test.
