A new scenario report in the Journal of the Endocrine Modern society documents how a patient’s use of a widespread biotin dietary supplement, also regarded as vitamin B7, caused her to have clinically deceptive take a look at benefits, which prompted many consultations and unnecessary radiographic and laboratory screening.
