Final answer:
The clean-catch urine specimen is also known as the midstream urine sample, which is used to avoid contamination by external genitalia in urine testing, such as a urinalysis or urine culture.
Step-by-step explanation:
The clean-catch urine specimen is also known as the midstream urine sample. This method involves collecting the urine sample not at the beginning or the end, but in the middle of urination. It is principally used to minimize the contamination from the external genitalia. Therefore, the correct answer is (b) Midstream urine sample.
The most common urine test is a urinalysis, which can entail a number of different investigative techniques depending on what condition is being screened for. If a bacterial infection is suspected, a urine culture may be performed in a laboratory setting to identify the offending bacteria and the most effective antibiotic treatment.
For an accurate diagnosis or regular health check-up, understanding how urine samples are tested, the significance of the results, and the rationale for specific collection methods like the clean-catch or midstream technique is vital.
