A urinalysis (or "UA") is an array of tests performed on urine and one of the most common methods of medical diagnosis.^[1] A part of a urinalysis can be performed by using urine dipsticks, in which the test results can be read as color changes.

Medical urinalysis

A typical medical urinalysis usually includes:

• a description of color and appearance.
• specific gravity - normally 1.010 to 1.030. This test detects ion concentration of the urine. Small amounts of protein or ketoacidosis tend to elevate results of the specific gravity.
• pH - normally 4.8 to 7.5.
• ketone bodies - normally negative (absent)
• protein - normally negative (absent)
• urobilinogen
• bilirubin
• glucose - normally negative (absent)
• RBC number
• WBC number
• hCG - normally absent, this hormone appears in the urine of pregnant women. Home pregnancy tests commonly detect this substance.
