What is the primary purpose of the two-identifier policy before imaging?

• A. To speed up the check-in process.
• B. To prevent misidentification and ensure the correct patient record is imaged.
• C. To verify insurance coverage.
• D. To determine eligibility for contrast media.

Answer: (B)

The main idea is to prevent misidentification by confirming the patient’s identity before any imaging is done. Using two independent identifiers—such as the patient’s full name and date of birth (or a medical record number)—enables the radiographer to verify that the imaging order belongs to the correct person and that the study is added to the right chart. This practice is a crucial safety measure: it reduces the risk of performing the wrong study, labeling errors, or mixing up patient records, which could lead to incorrect diagnoses, inappropriate treatment, or legal consequences for the provider and facility. It’s about accuracy and accountability, supported by safety guidelines that require reliable patient identification. It’s not about speeding up check-in, verifying insurance, or deciding whether someone qualifies for contrast media, which are separate administrative or clinical processes.
