Who is permitted to conduct blood tests?

The correct answer identifies that blood tests should only be conducted by a physician, nurse, or another qualified person. This stipulation is essential for ensuring that the procedure is performed safely and accurately, as it involves both medical knowledge and technical skill. Trained professionals understand how to handle blood samples properly, are aware of the potential for complications, and know how to interpret the results within a clinical context.

The role of providing medical care, including blood draws, requires specific training that goes beyond general knowledge and includes knowledge of anatomy, aseptic techniques, and the management of potential health risks.

Options that allow for a broader range of individuals to conduct blood tests lack this necessary oversight and expertise, which could compromise the integrity of the testing process and patient safety.
