EndoLab Diagnostic Services

As a division of American Hormones, EndoLab is dedicated to the highest quality diagnostic testing and rapid turnaround time for results. EndoLab provides serum diagnostic hormonal assays. We use the Immulite Chemiluminescent Immunoassay system, which is designed for reliability. This system has a broad menu, which is used along with the industry gold standard of Radio Immuno-Assay (RIA). EndoLab will provide serum hormone level results with unique ranges based on sex, age, and physiologic state, unlike other laboratories with too broad of a demographic spectrum. With our diagnostic blood testing services, you can make more precise interpretations and accurate hormone replacement dosage decisions.

All our tests, including metabolic blood testing, are conducted in-house under the supervision of the Medical Director and our Endocrinology consultants. Your local and regional laboratories reference these unique tests out to research laboratories such as ours. EndoLab is equipped and designed to do these assays in-house, and your results come directly from us. There is less decay of specimens in transit from one laboratory location to another, and you are assured of the sensitivity and specificity of RIA and Immulite.
