@stormlight I don't know the technical differences. All I know is that when I was dealing with the situation, the doctor and lab both explained that you need the same type each time because the measurement standards are different. My doctors and endocrinologist who took over my post surgical care preferred the serum cobalt test. That was 11 years ago, standards may have changed.
