Question

The microscopic examination is most frequently done on which type of sample for routine screening?

1) Random samples
2) First morning sample
3) Urine samples
4) Blood samples

Answer 1

Routine microscopic examinations for screening are most frequently done on first morning urine samples as they provide a more concentrated sample for detecting abnormalities.

Step-by-step explanation:

The microscopic examination for routine screening is most frequently done on first morning urine samples. This type of urine sample is typically more concentrated and will contain higher levels of any abnormal substances or cellular elements that may be present. A routine urinalysis includes physical examination, chemical analysis, and microscopic examination to detect elements such as proteins, red blood cells, pus cells, bacteria, and cellular casts. Although similar tests can be done on blood samples, the context of routine screening and microscopic examination pertains specifically in this case to urine samples.
