00:00 So let's wrap up this part of the video series.

00:03 A urine specific gravity is a routine part of every urine analysis.

00:07 Hey, that's cool, cuz you're going to see a lot of urine analysis, meaning you're going to have a lot of exposure to urine specific gravity.

00:15 Now, urine specific gravity test compares the density of urine with a density of pure water, and that shows us the concentration of all the chemical particles in the urine.

00:25 Alright, I don't want to go on to the next point til you make sure that's clear for you.

00:30 A urine specific gravity test compares the density of urine to the density of pure water.

00:36 Now, let's look at the next node.

00:38 So we know that urine is a solution of minerals, salts, and compounds dissolved in water.

00:45 So since we compare that to water, which is 1.0, the normal specific gravity has to be greater than 1.0.

00:55 Okay, so you've got those solid.

00:58 Let's move on to the next point.

01:00 1.010 to 1.030 is one example of a normal range.

01:06 Remember, it's going to be greater than 1.00 because the urine has substances dissolved in it.

01:13 Urine specific gravity that are outside of the normal range have multiple possible causes and require your additional assessment.

01:21 Thank you for watching our video today.

The lecture Urine Specific Gravity Test: In a Nutshell (Nursing) by Rhonda Lawes, PhD, RN is from the course Urine Specific Gravity – Urinalysis (Nursing).

### Included Quiz Questions

1. It compares the density of urine to the density of water
2. The normal specific gravity of urine is 1.0
3. It is done separately from the urinalysis
4. The cause is always an issue with the kidney function
