How do you read a refractometer for a urine test?
Knowing how to use a refractometer for urine is crucial to determining the urine specific gravity; a measurement of concertation levels that can reveal overall hydration. Begin the process by cleaning your urine refractometer with distilled water and wiping dry with a soft cloth. Make sure it is also correctly calibrated. Take your sample of urine and use a pipette to place a drop onto the glass measurement surface before closing the flap. Point the refractometer at a light source and simply read the specific gravity level from the scale inside the device.
What does a refractometer measure in urine?
A digital or analogue urine refractometer can be used to measure specific urine gravity, the refraction index and the serum content (serum protein in urine):
- Urine Specific Gravity: This is a measurement of the concentration of a urine sample. This allows us to monitor hydration levels in the body which can be useful for medical or sports related tasks.
- Refraction Index: The refraction index measures the degree of which a light is bent (or refracted) when shone through a urine sample. This tells us the concentration of a liquid and can later be converted into the Brix scale.
- Serum Content: The ability to measure serum protein (S.P.) in urine is another important application of a urine refractometer. This information can be used to spot medical issues such as kidney failure or kidney disease.
