I just did my pulmonary function test last Friday for another department. It's a tough test, the three tests have to be within 5% of each other. My output was 91% which was good, but could have been better. My third test was 6.4% three times, kind of a pain. If they told you that you passed then you are all set. The minimum two exams that have to be administered in MA in order to be a PO (municipal) are the Pulmonary Function test and Audiogram. You must pass both of them. Good luck!
