The technician should_____. adjust the screw set to 1.000 and then continue with patient testing. A clear yellow urine will NOT contain any pathologically significant constituents. False. Proper care of reagent strips includes: Final answer: The actual specific gravity of the urine sample after a 1:2 dilution with a refractometer reading of 1.030 is 2.060.Specific gravity helps in assessing the urine density in comparison to pure water, indicating various health conditions.
Once a month, the refractometer is checked for accuracy by measuring the specific gravity of water (considered a standard) which should read 1.000 ± 0.001. To verify the accuracy at a high specific gravity, the MAS Level 1 Liquid Urinalysis Control Solution is run. 4. Expected RangeThe color of a urine specimen containing blood can be attributed to all of the following except the: A. Amount of blood B. Blood type of patient C. pH of the urine D. Length of contact

how to read a refractometer
A urinometer reads 1.003 in distilled water. Water has a specific gravity of 1.000. Therefore, 0.003 is the correction of the urinometer that should be subtracted from the subsequent relative specific gravity. If the specific gravity is 0.037, minus this value with 0.003 and it will result in the corrected specific gravity of 1.034. Bausch and Lomb Refractometer. Use distilled water as a test sample to learn how to use the refractometer; its index of refraction is 1.3329 at 25°C. . Re-illuminate the scale, and read to 5 significant figures using the top .Specific Gravity is a comparison of the weight of a drop of urine to of a drop of distilled water. Distilled water weighs 1.000. If the specimen submitted is urine, then it should be somewhat heavier than water and within a “normal” range for specific gravity. For laboratory purposes, the range for normal specific gravity is 1.003 to 1.040.Given the following information , calculate the patient's free water clearance : urine volume 360 mL in 12 hours , urine osmolality - 1400 mOsm , and plasma osmolality - 275 mOsm . .
