Urine glucose 2 +, review and normal, need to measure fasting and 2 hours postprandial blood glucose assessment of blood glucose; at the same time, need to improve the urine microalbumin/creatinine (ACR) or urine protein quantification, assessment of renal function; secondly, attention should be paid to several times the review, assessment of the condition.
1. Increased glucose diabetes mellitus: diabetes mellitus is the most common, and diabetes mellitus occurs when blood glucose is elevated above the renal glucose threshold. Therefore, even if the urine glucose is 2+, even if the retest is normal, fasting and 2-hour postprandial blood glucose should be measured for evaluation, and if there is an increase in blood glucose, an oral glucose tolerance test should be done to clarify whether diabetes can be diagnosed.
2. Normal glucose diabetes: when blood glucose is normal, urinary glucose occurs when the renal glucose threshold decreases, i.e. renal diabetes. It is common in chronic nephritis, nephrotic syndrome, etc. At this time, it is necessary to improve the urine ACR or urine protein quantification, to assess the renal function, and if necessary, it is necessary to actively treat the primary disease.
3. Temporary diabetes: physiological diabetes can be seen in eating a large number of carbohydrates can lead to transient elevation of blood glucose, positive urine glucose; stress diabetes, such as craniocerebral trauma, acute myocardial infarction can be temporary hyperglycemia and diabetes. Positive urine glucose in this case is generally accidental, attention to review.
4. False Glycosuria: The presence of vitamins, isoniazid and streptomycin in the urine can make the urine glucose test appear false positive. Note that the specimen should be standardized, and eat less vitamin-rich food or the above drugs before urine retention, so as not to cause false positives.
Positive urine glucose, after reviewing the normal also need to timely regular hospitals to improve the relevant examination, to exclude pathological diabetes, so as not to delay the condition.
