Nocturnal Hormone Profiling

Meaning

Nocturnal Hormone Profiling is a specialized diagnostic technique involving the collection of biological samples, such as saliva or urine, during the sleep cycle to accurately measure the secretion and metabolism of hormones throughout the night. This approach is essential for capturing the critical pulsatile release of anabolic hormones and assessing the nighttime nadir of catabolic hormones like cortisol. It provides a truer representation of the neuroendocrine axis function than a single daytime blood draw.
