Question

A urine specific gravity measured by refractometer is unexpectedly high. Which substance is most likely to cause this discrepancy?

Accepted Answer

보기 3: Glucose or protein present in high concentration

A refractometer measures refractive index, so large heavy molecules raise the reading. Substantial glucose or protein therefore produces a specific gravity higher than the true degree of concentration. Correct the value or confirm with osmolality.

Answer

보기 2: Urobilinogen present in a markedly increased amount

Answer

보기 4: Nitrite produced by urinary bacteria
