Step 1 of 2

Sterile specimen:

The sterile specimens are the one which has no pathogenic microorganisms in it.

• In urinalysis, every test is done under sterile conditions but in suprapubic aspiration specimen, the sample is collected by the needle that is inserted into abdomen directly in the most sterile condition.

• It is the most sterile specimen, because it prevents the pathogenic entry as the sample was collected directly from the urinary bladder with a sterile needle option and the urinary bladder will also be in sterile condition.

Therefore, “suprapubic aspiration” is the most sterile specimen collected. Hence, the correct answer is option.
