The small amount of radiation makes the film cassette glow based on how much radiation gets through the body. The denser the material in the body, the lighter in color the film will be directly behind that area. For example, bone is very dense and will appear very light on the film cassette.

After a urine specimen is collected, a stick with small squares of chemicals is dipped into the sample of urine. The urine reacts with the chemicals causing a chemical reaction shown by a change in color. This change in color shows the levels of each of the tests on the strip; this is compared with a baseline with normal ranges on the manufacturers bottle. The urine is also assessed on its physical appearance such as cloudiness, clarity, color, quantity, and odor. Microscopic urinalysis is done under a microscope. It shows the cells, cellular debris, bacteria, and crystals that can be clues in diagnosis or confirm dipstick results. Microscopic urinalysis is done by centrifuging the sample, and then taking the solid part at the bottom of the test tube mixed with a small amount of urine and then put under a
