Testing for Safety and ****Effectiveness***

Pat is first tested in the lab to see whether he might work. If these tests show promise, Pat starts "clinical trials." These are medical tests on thousands of volunteers. Pat is tested under very close medical supervision. This testing process takes many years. The testing sees if Pat improves patients' health and what kind of side effects he causes.
