Urinalysis

Urinalysis is a test of your urine. It is used to detect and treat a variety of conditions such as urinary tract infections (UTIs) or diabetes. A urinalysis is easily collected and involves the patient providing a small sample of their urine – usually clean catch- which is then tested by means of a testing strip and/or analyzer. The testing strip/analyzer checks for color/appearance of the urine, concentration, presence of blood, ketones, and other factors.

 

Normal values are as follows:

  1. Color – Yellow (light/pale to dark/deep amber)

  2. Clarity/turbidity – Clear or cloudy.

  3. pH – 4.5-8.

  4. Specific gravity – 1.005-1.025.

  5. Glucose - ≤130 mg/d.

  6. Ketones – None.

  7. Nitrites – Negative.

  8. Leukocyte esterase – Negative.

 

 

How to perform a “CLEAN CATCH”

A “clean catch” is performed to prevent bacteria from the skin of the genitals from contaminating the urine specimen.

 

INSTRUCTIONS FOR FEMALES

  1. Wash hands with soap and warm water.

  2. Spread the labia (folds of skin) apart with one hand and wipe with the towelette provided.

  3. Wipe from front to back.

  4. Continue holding the labia apart. As you start to urinate, allow a small amount of urine to fall into the toilet bowl. (This clears the urethra of contaminants) Do not touch the inside of the cup.

  5. After the urine stream is well established, urinate into the cup. Once an adequate amount of urine fills the cup (the cup only needs to be half-full), remove the cup from the urine stream.

  6. Pass the remaining urine into the toilet.

  7. Screw the lid on the cup tightly (do not touch the inside of the cup or lid).
