Urinalysis begins with a macroscopic examination of the urine which describes the color and clarity of the urine. In healthy individuals urine color ranges from pale yellow to amber, depending on their state of hydration. Many factors affect urine color including fluid balance, diet, medications and disease. The following table includes a list of the most common causes of abnormal urine coloration. Urine samples are initially screened with dipsticks. Performing microscopic analysis on only dipstick positive urine samples is cost effective when the patient population being tested has a low incidence of potential disease.

When you have symptoms, such as abdominal pain, back pain, frequent or painful urination; sometimes as part of a health examination, pregnancy check-up, hospital admission, or pre-surgical work-up. One to two ounces of urine—a sufficient sample is required for accurate results; sometimes you may be directed to collect a sample using a "clean-catch" technique: women should spread the labia of the vagina and clean from front to back; men should wipe the tip of the penis.

A urine test strip or dipstick is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. A standard urine test strip may comprise up to 10 different chemical pads or reagents which react change color when immersed in, and then removed from, a urine sample. The test can often be read in as little as 60 to seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases.
