Disadvantages It might not always yield to accurate result as urine test using a test strip is time-sensitive. The https:// ensures that you are connecting to the National Athletic Trainers' Association position statement: fluid replacement for athletes. 11. deteremines concentration of dissolved substances in specimen. Urine specific gravity is a measure of the ratio of the density of urine to the density of water. Refractometers are especially useful for determining urine specific gravity on veterinary samples because they require relatively small sample volumes. The N-MULTISTIX 10 SG Reagent Strips (Miles Laboratories, Inc, Elkhart, IN) have a specific-gravity scale ranging from 1.000 to 1.030, with color blocks in intervals of 0.005 units. In conclusion, our results suggest that the refractometer is a reliable measure of urine specific gravity. (PDF) Comparison of Refractometry, Urine Color, and 'Specific gravity' is a function of the number, density and weight of the solute particles present in the urine, and is used as a measure of the concentrating power of the kidney. 8600 Rockville Pike Best answer . Sep-Oct 1998;24(5):480-2. Blood and urinary measures of hydration status during progressive acute dehydration. It counts the components of urine in detail such as the type of cells present, crystal formation, cast, bacteria, mucus, and other components. Easy to interpret Cost-effective The analysis can be done in just a few minutes of collecting urine. The urinometer is an laboratory material that normally used to measure the specific gravity of urine . The NCAA selected urine specific gravity as the most practical, cost-efficient hydration measure to use during the weight-certification process.4. The refractometer has advantages over other methods of estimating IgG concentration in that the Brix refractometer is inexpensive, readily available, less fragile, and less sensitive to variation in colostral temperature, season of the year and other factors. WebThe refractometer is reliable, fast, accurate, and technically easy to use and requires only a single drop of urine. The refractometer and hydrometer were reliable between trials, but the reagent strips were not. This may reflect tester subjectivity and the difficulty in determining the density-indicating meniscus. Bland-Altman plot for refractometry and hydrometry. advantages of refractometer compared to urinometer. 2 What are the advantages of refractometry? The .gov means its official. The reading should be done within a few minutes.
