A routine urine test cannot tell if blood sugar is high, but a routine urine test can indicate if blood sugar is elevated. Routine urine has indicators called urine sugar, which shows negative in normal people and usually indicates high blood sugar if it is positive, especially if it shows 1-3 (+). You can go to the endocrinology department for an in-depth examination to determine the presence of diabetes, and urine routine is one of the most commonly used routine tests. The urine routine test indicators can help determine if there is a problem and what areas are problematic. For example, an increase in urine protein may indicate a medical problem, especially a nephrological problem, and an increase in urine sugar may indicate diabetes mellitus. An increase in red blood cells suggests a hematuria problem, but it is important to distinguish between the source of the hematuria, medical or surgical. Leukocytosis suggests an infection problem, so urine routine is very important for disease determination.
