WebTo compare hydration levels of athletes using a refractometer and an osmometer, based on urine measures. (Level 2) 13. Combination of an Axicon Fiber Tip and a Camera Device into a Sensitive Refractive Index Sensor. National Collegiate Athletic Association Wrestling Rules Committee. As mentioned above, they are not as great post fermentation and only a hydrometer will What are the advantages of refractometry? 5,7 The advantages of refractometric USG are that it can reliably and immediately be determined from a droplet of urine, using a simple and inexpensive urinary refractometer that reflects the concentration of a urine sample. When performing the test in a laboratory setting, you will be given a sterile container to catch the urine sample. Urine with low specific gravity can be a sign of diabetes or kidney problems. Urinometer What are the benefits of a refractometer? Open up the flap at the end of the refractometer. Calibrate the refractometer by placing distilled water on the glass as the sample, 3 Measurement. Make sure you submit a fresh urine sample. Each tester measured the specific gravity of each urine subsample in the following order: reagent strip, hydrometer, and refractometer. Easy to operate - Simply read the instructions that accompany the refractometer. Best answer . The .gov means its official. Refractometer vs. Hydrometer Pros and Cons - Homebrew Talk These wrestlers were dehydrated, but the hydrometer or reagent-strip measurement indicated euhydration, allowing the establishment of a weight class. A urine test is not a definite diagnosis of a particular condition. and transmitted securely. Whereas hydrometers measure specific gravity (SG) based on the density of a liquid, refractometers determine SG using refraction of light. Kristin J. Stuempfle, PhD, ATC, contributed to conception and design; acquisition and analysis and interpretation of the data; and drafting, critical revision, and final approval of the article. It does not store any personal data. Urine specific-gravity measurements normally range from 1.002 to 1.030.5 The NCAA selected a urine specific-gravity measurement of 1.020 to indicate euhydration.4 Wrestlers with a urine specific gravity 1.020 are considered euhydrated and may have their body composition assessed to determine their minimal weight for competition, whereas wrestlers with a urine specific gravity >1.020 are considered to be dehydrated and may not proceed to body-composition testing on that day.
