<prompt> Renal threshold for glycosuria100 mgdl180 mgdl300 mgdl350 mgdl  <response>: For glucose, the renal threshold is 180 mgdl and Tm is 375 mgmin. In other words, glucose stas to appear in urine when blood level is more than 180 mgdl, and all the glucose molecules above 375 mg are excreted in the urine. abnormal conditions, the renal threshold may be lowered so that even at lower blood levels, compounds are excreted in urine, e.g. renal glycosuria glucose; and renal tubular acidosis bicarbonate.Ref: DM Vasudevan, 7th edition, page no: 316
