Systemic steroid hormone measurements are often used in the assessment of reproductive,
developmental, and stress physiology in vertebrates. In protected wildlife, such as the
common bottlenose dolphin (Tursiops truncatus), these measures can provide critical
information about health and fitness to aid in effective conservation and management.
Circulating steroid hormone concentrations are typically measured by immunoassays, which
have imperfect specificity and are limited to the measurement of a single hormone per …
