How Does A Urinometer Operate

How use urinometer step by step?

1) Fill the urinometer cylinder to about one inch from the top with urine specimen; measure and record specimen temperature. 2) Hold the urinometer float by the top and slowly insert it into the cylinder.

How does urine specific gravity work?

A urine specific gravity test compares the density of urine with the density of water. It allows doctors to see the concentration of all particles that are present in the urine. The test involves collecting a urine sample that will help give a doctor an idea of a person's kidney function and hydration status.

How does a urinometer read specific gravity?

What is the use of Urometer?

An Urinometer is a simple piece of equipment for determining urine specific gravity. A typical urinometer is composed of a float, a weight, and a stem.

What is the best preservative for urine?

The commonly used urine preservatives include boric acid, hydrochloric acid, acetic acid, and oxalic acid. Certain buffers and bicarbonate salts may also be used for specific measurands.

What are the advantages of urinometer?

Advantages are, only one or two drops of urine is sufficient and temperature correction not necessary. ii. Harmonic oscillation densitometry: the principle is – principle that the frequency of a sound wave entering a solution changes in proportion to the density of the solution.

What correction is required in the specific gravity measured by urinometer which is calibrated at 20 C?

subtracted if lower than the calibration temperature. For example, if the specific gravity of the urine is 1.022 at 23oC, and the urinometer has been calibrated at 20 oC, the correct reading is 1.022+0.001= 1.023.

How is urine measured in Urometer?

For sampling use the sampling port provided on the tapered connector. Drain out the urine using the bottom urine Urometer. Drain out the urine from the measured volume into the collection bag. check the urine volume periodically and drain into the collection bag and mention volume urine output on the nursing note.

Does drinking water affect urine test?

If a tester drinks large amounts of water (at least one gallon) before taking a drug test, urine becomes diluted and metabolites from drugs may become undetectable. This may cause the first round of results to be inconclusive.

How do you increase urine specific gravity?

Glucose, protein, or dyes used in diagnostic tests excreted into the urine increase the specific gravity.

What happens if specific gravity of urine is high?

Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be. High urine specific gravity can indicate that you have extra substances in your urine, such as: glucose.

What is the normal pH of urine?

Normal Results

The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples.
