A urinalysis is a group of manual
and/or automated qualitative and semi-quantitative tests performed
on a urine sample.
A routine urinalysis usually
includes the following tests: color, transparency, specific
gravity, pH, protein, glucose, ketones, blood, bilirubin, nitrite,
urobilinogen, and leukocyte esterase. Some laboratories include a
microscopic examination of urinary sediment with all routine
urinalysis tests.
The nurses should be aware of the
purposes of urinalysis
- general health screening to detect
renal and metabolic diseases
- diagnosis of diseases or disorders
of the kidneys or urinary tract
- monitoring of patients with
diabetes
For collecting 24 hr urine
sample
- Nurses should advice the patient
that
- On day 1, urinate into the toilet

- Afterwards, collect all urine in a
special container for the next 24 hours.
- On day 2, urinate into the
container when get up in the morning.
- Cap the container. Keep it in the
refrigerator or a cool place during the collection period.
- Label the container with name, the
date, the time of completion, and return it as instructed.
- For an infant, thoroughly wash the
area around the urethra.
- Open a urine collection bag (a
plastic bag with an adhesive paper on one end), and place it on the
infant.
- For males, place the entire area in
the bag and attach the adhesive to the skin. For females, place the
bag over the labia. Diaper as usual over the secured bag.
- Check the infant frequently and
change the bag after the infant has urinated into it. Drain the

Clean catch urine
specimen
- A clean catch is a method of
collecting a urine sample for various tests, including urinalysis
and urine culture.
- Advice the patient that
- To obtain a clean-catch urine
sample, boys and men should wipe the and clean the area. Girls and
women need to wipe between the area of collection with soapy water
and rinse well.
- To perform this test, first urinate
a small amount into the toilet bowl to clear the urethra of any
contaminants.
- Then, collect a sample of urine in
a clean or sterile container. About 1 – 2 ounces of urine is needed
for a test. Remove the container from the urine stream without
stopping the flow.
- For infants, the genital area is
cleaned and dried, and then a collection device is attached to
collect the urine.
- Take the measures to prevent
leakage. After the baby has urinated, the urine (at least 20 cc) is
placed in a sterile container.
- Do not use antiseptics, as they may
prevent bacteria from growing during the culture.
