Endocrine Labomas

Laboratory endocrinology forms an integral part of 21(st) century endocrinology. Perhaps, no other specialty of medicine is as closely associated with laboratory as endocrinology. This review intends to highlight the challenges faced by an endocrinologist before interpreting a hormone assay report. This review by no means is holistic but intends to highlight some of the pitfalls of laboratory endocrinology and arouse further interest in this important but neglected section of endocrinology. Lack of standardization, as well as rigorous implementation is some of the major challenges facing endocrine assays in our country. It is essential to be aware not only of the details of the method of analysis of a hormone, the pre-analytical requisites, but also disease-specific analytical issues to prevent unnecessary concern both for the patient, as well as the treating physician, as well as needless investigations. Problems with interpretation of serum prolactin, thyroglobulin, steroid hormone assays, rennin assay and vitamin-D assay have been highlighted.
