[Determination of the specific gravity of the urine using a refractometer].
A method is proposed for urine specific gravity determination by urine refractometric index reading. Only two-three drops are required. Abbe refractometer is used. The urine specific gravity is determined by the formula: (formula: see text), where y = urine specific gravity, x = the refraction read. The method could not be used in cases with glucosuria and ketoniria as well as in case of a considerable proteinemia. The author's results correlate with the results of some foreign authors.
