The correct answer involves the process of urinalysis, which specifically centers around collecting a urine sample for testing. This procedure typically begins with patient instruction on how to obtain a clean catch midstream urine sample, which helps minimize contamination from the skin or external genitalia and provides a more accurate analysis of the urine.

Once the sample is collected, various tests can be performed, including physical, chemical, and microscopic examinations. The physical examination assesses color, clarity, and specific gravity. The chemical analysis tests for the presence of substances like glucose, protein, ketones, nitrites, and pH level. Finally, a microscopic examination may be conducted to identify cells, bacteria, crystals, and other components that could indicate underlying health issues.

The other options refer to procedures unrelated to urinalysis. DNA tests involve analyzing genetic material, which is not part of a urinalysis; collecting hair samples is irrelevant to urine analysis; and preparing blood samples is a different type of diagnostic procedure. Therefore, the emphasis on collecting a urine sample accurately represents the fundamental step in performing a urinalysis.
