California Certifying Board for Medical Assistants (CCBMA) Practice Test

The suffix that indicates a written record in medical terms is -gram. In medical terminology, -gram is often used to denote the result of a recording or imaging process. For example, in terms like "electrocardiogram" or "mammogram," the suffix refers to the written record produced by the respective tests.

The other suffixes, while related to recording or measuring, have distinct meanings. For instance, -graph indicates the instrument used to produce the record, whereas -scope refers to an instrument used for viewing or examining. -metry pertains to the measurement of a specific parameter, which does not necessarily imply a written record. Thus, -gram is specifically tied to recorded information in medical contexts.
