Becoming certified in administering and interpreting DEXA scans establishes a level of commitment and accountability in the industry. It increases employer confidence in your ability; it also helps identify you as a quality service provider to patients.
There are various levels of DEXA scan certification. Certificates exist for performing scans--such as a bone densitometry technologist certificate--while the clinical densitometrist certificate is for those who will interpret results. Be sure to pick the certification that best suits your situation. Once you have completed the course and test, you will be considered certified.
A certification shows that you have met certain training requirements, while a license usually involves state specific laws. In some states, you must be a registered technologist to perform DEXA scans, while other states have less specific requirements. For your protection, be sure that you are in full compliance with state regulation.
