Urine sugar

Urine sugar refers to sugars in urine, mainly glucose in urine. Normal people have very little urine sugar, which can not be measured by normal methods, so normal people should have negative urine sugar, or there should be no sugar in urine. In normal people, only when the blood glucose exceeds 160-180 mg / dl, sugar can be excreted from the urine more, forming urine sugar. Therefore, the level of blood glucose determines the presence or absence of urine glucose: blood glucose is 180-200mg / dl, urine glucose should be ±; blood glucose is 200-250mg / dl, urine glucose should be +; blood glucose is 250-300mg / dl, Urine sugar should be ++; blood glucose should be 300 to 350mg / dl, urine sugar should be ++; blood sugar above 350mg / dl, urine sugar should be ++++.
