Most physiologists required a Ph - D degree and licensing. Before taking any exams required by their state, they must pass the Foreign Pharmacy Graduate Equivalency examination (FPGEE), Test of English being a Foreign Language (TOEFL) and Test of Spoken English (TSE) exams. An individual that finds work within this profession can be considered a radiology technician if his competency qualifies him to do work using x-ray, ultra-sound, CAT or ECG equipment providing you with the doctors with scanned images that the latter use as bases for diagnoses. #cytoxan
