Why is Specific Gravity of Urine Important?

Specific gravity of Urine can be used to test for many different diseases and disorders. Specific gravity of urine not only can test for symptoms in humans but also in animals.

Using Specific Gravity of Urine to Discover & Fight Disease

Specific gravity of urine can be affected by a range of diseases and disorders ranging from diabetes to urinary tract infections. This is why testing specific gravity is so critical in this day and age.

In a normal individual the specific gravity of urine is in direct proportion to the amount of urea present. The normal range is from 1.010 to 1.30. Abundant urine of low specific gravity is suggestive either of diabetes incipidus or of chronic renal disease. Abundant urine of high specific gravity is characteristic of diabetes mellitus. In the latter condition the specific gravity may reach 1075. In most cases it is between 1040 to 1045. In diabetes incipidus, on the other hand, the specific gravity may fall nearly to that of distilled water. The presence of albumin in the urine does not materially affect its specific gravity.

Inside a person the particular gravity of urine is within direct proportion to the quantity of urea present. The standard range comes from 1.010 to at 1.30. Abundant urine of low specific gravity is suggestive either of diabetes incipidus or of chronic kidney disease. Abundant urine of high specific gravity is sign of diabetes. Within the latter condition the particular gravity may achieve 1.075. Generally it's between 1.040 to 1.045. In diabetes incipidus, however, the particular gravity may fall nearly to that particular of sterilized water. The existence of albumin within the urine doesn't materially affect its specific gravity.

Atago's PAL-10S and Pen Pro Specific Gravity Refractometers

The PAL-10S unit has a sample stage that requires one drop of urine to give accurate results. It is easy to clean simply by using a swab with some rubbing alcohol. In total it takes about 3 seconds for the unit to show the digital results from the test and after a quick cleaning, another sample can be applied immediately.

The Atago Pen Pro was made to directly replace the "dip" style strips that researchers still use to this day. This refractometer is made to be dipped into a cup filled with a urine sample and with 3 seconds the reading is given on the clear digital display.

The Atago Pen Pro is extremely easy to clean just like the PAL-10S. Just take a cotton ball or swap with some rubbing alcohol and gently rub the optical prism.

Recent Study at NIH Proves Digital Urine Refractometers are Superior

Leading scientists at the National Institute of Health (NIH) show that using a digital refractometer is best for urine analysis. The refractometer method of determining urine specific gravity is desirable because specific gravity measurements are performed on as little as one drop of urine.

Here is what the research showed: (This study was conducted by testing the specific gravity of urine of wrestlers).

"Refractometer measurements were consistent between trials (R = .998) and among testers; hydrometer measurements were consistent between trials (R = .987) but not among testers; and reagent-strip measurements were not consistent between trials or among testers. Hydrometer (1.018 ± 0.006) and reagent-strip (1.017 ± 0.007) measurements were significantly higher than refractometer (1.015 ± 0.006) measurements. Intraclass correlation coefficients were moderate between refractometry and hydrometry (R = .869) and low between refractometry and reagent strips (R = .573). The hydrometer produced 28% false positives and 2% false negatives, and reagent strips produced 15% false positives and 9% false negatives.
Conclusions:
Only the digital refractometer should be used to determine urine specific gravity in collegiate wrestlers during the weight-certification process."
