peptide releasing experiments

[kingmanzhang]

For stimulated peptide release experiments, such as C peptide release upon glucose stimulation, @pnrobinson you annotated all of them to "Abnormal C peptide level". Is this really what we want to annotate? I think they are testing beta cell function. There are other similar tests, such as prolactin secretion upon stimulation, Thyroxine release upon stimulation etc that will follow the same logic.
