Comparison of Specific Gravity and Creatinine for ...

Background: Specific gravity (SG) may perform as well as creatinine (CR) correction for adjusting urinary hormone concentrations, as well as offer some advantages. We compared the two methods and applied them to US and Bangladeshi specimens to evaluate their use in different populations. Methods: Pearson correlations between serum concentrations and SG, CR, and uncorrected urinary ...

Urine Specific Gravity Test - healthhearty

The specific gravity normal range is often found to vary. However, 1.010 to 1.035 g/ml or 1.005 to 1.030 g/ml are considered as the normal ranges of this test. The following are the causes that can increase or decrease the concentration, and hence, specific gravity of urine.

Quick Test Method for Determining Specific Gravity of ...

The normal method of determining specific gravity is to weigh the specimen dry (DW), then to suspend the specimen in water on a string, and to measure the weight pulling on the string (WW) (specimen weight suspended in water). Then you subtract WW from DW, and divide the difference into DW.

Specific Gravity Test - testing urine for specific gravity

Specific Gravity: Elevated levels of protein in urine may cause abnormally high specific gravity values. Oxidants/PCC: Normal human urine should not contain oxidants or PCC. The presence of high levels of antioxidants in the specimen, such as ascorbic acid, may result in false negative results for the oxidants/PCC pad.
