Can the medical electronic instrument and maintenance major test pharmacists?

You can't. Their professional fields and work contents are different, so the pharmacist examination can not be used as a necessary condition for medical electronic instruments and maintenance. The study and work of medical electronic instrument and maintenance major mainly involves the knowledge and skills of medical equipment maintenance and management. Students need to learn knowledge in many fields, such as medicine, electronic engineering, machinery manufacturing and so on, in order to master the maintenance and repair technology of medical equipment. Pharmacists need to learn pharmacology, pharmacy and clinical medicine knowledge, mainly engaged in drug treatment and drug management.
