Question

Quizplus · Accepted Answer

Swabbing the liquid blood and allowing it to dry on the sterile swab is the appropriate method for collecting a liquid sample. This method prevents contamination and preserves the integrity of the sample. Cutting out the floor or scraping dried blood flakes can destroy evidence and contaminate the sample. Drawing blood into a pipette and storing it in a paper bag can also lead to contamination and compromise the integrity of the sample.
