Includes
Glucose, protein, bilirubin, urobilinogen, pH, blood, ketones, nitrite, leukocytes,specific gravity,and color.
A microscopic exam of the urine providing a qualitative or quantitative count of formed elements such as cells, casts, crystals, and organisms.


Preferred Specimen
Freshly voided urine sample collected by the "clean catch" method in clean urine container


Minimum Volume
4mL


Other Acceptable Specimens
BD Vacutainer Plus UA Preservative Tube (Yellow and Red tiger top tube)

BD Vacutainer Urinalysis tube, No additive (Yellow top tube)


Instructions
To collect a clean-catch urine specimen from an adult male:
  1. Have the patient wash his hands.
  2. Instruct the un-circumcised patient to withdraw the foreskin to expose the urethral meatus.
  3. With a sterile cleansing towelette or the equivalent, cleanse the glans, beginning at the urethra and working away from it.
The patient should begin urination, passing the first portion into the bedpan or toilet. Collect the midportion in the appropriate container without contaminating the container. Any excess urine should be passed into the bedpan or toilet
To collect a clean-catch urine specimen from an adult female:
  1. Have the patient wash her hands with soap or a towelette.
  2. Instruct the patient to position herself over the bedpan or toilet.
  3. Using a sterile cleansing towelette or the equivalent, the patient should cleanse the urethral meatus and surrounding area.
The patient should begin to urinate, passing the first portion into the bedpan or toilet. The midportion should be collected into the appropriate container without contaminating the container. Any excess urine should be passed into the bedpan or toilet
 


Transport Temperature
Room temperature preferred


Specimen Stability
Fresh voided urine Room Temperature: 2 hours
                               Refrigerated: 24 hours
Preservative Tube Room Temperature: 72 hours

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Grey top tubes.
Grossly bloody specimens cannot be run on the ichem Velocity.  Diluted grossly blood specimens can be run on the iQ200 for microscopics.  Gross hematuria may cause incorrect results in subsequent samples.

Clinical Significance

A urinalysis is a group of physical, chemical, and microscopic tests. The tests detect and/or measure several substances in the urine, such as byproducts of normal and abnormal metabolism, cells, cellular fragments, and bacteria.

Urine is produced by the kidneys, two fist-sized organs located on either side of the spine at the bottom of the ribcage. The kidneys filter wastes out of the blood, help regulate the amount of water in the body, and conserve proteins, electrolytes, and other compounds that the body can reuse. Anything that is not needed is eliminated in the urine, traveling from the kidneys through ureters to the bladder and then through the urethra and out of the body. Urine is generally yellow and relatively clear, but each time a person urinates, the color, quantity, concentration, and content of the urine will be slightly different because of varying constituents.

Many disorders may be detected in their early stages by identifying substances that are not normally present in the urine and/or by measuring abnormal levels of certain substances. Some examples include glucose, protein, bilirubin, red blood cells, white blood cells, crystals, and bacteria
