I actually do understand the difference between statistically significant and clinically significant accuracy. We are taught that in school. It seems like you're the one who feels threatened. I joined this site to get a nursing perspective on the different roles of hospital staff with the hopes of educating and in return learning something new. Every department in a hospital serves as a check and balance for each other. Nurses have an important role in patient care, but so does the lab and respiratory therapy and radiology, etc. I have close friends and family who are nurses, so I know what your education and work experiences include. On the other hand it seems very few nurses understand the educational requirements for the other staff. You think patient care is solely in your domain and I feel sorry for you. You go ahead and think what you want about the lab though, I know why I became a Medical Laboratory Scientist. It was to help patients. By the way, POCT falls under the lab, so even though you run the test, a MLS still makes sure that everything is done correctly. Quality control, correlation studies, calibration verification, etc is all overseen by lab.
