Diagnostic Innovation

Nichols Institute is at the forefront of the clinical laboratory industry thanks to the combined efforts of our scientific and medical staff and our collaboration with Academic Associates and members of the biotechnology industry. Because we're the leader in transferring diagnostic innovation from academia and the biotechnology industry, we have often been among the first to bring new assays and technologies to the commercial marketplace.

Comprehensive Offerings

We also offer tests and screens for more prevalent endocrine disorders, including PCOS, Vitamin D deficiency, diabetes, adrenal dysfunction, pediatric endocrinology and growth disorders, infertility and osteoporosis. But it isn’t simply the breadth of offerings, it’s our depth: Our portfolio of endocrinology tests relevant to PCOS encompasses Free and Total Testosterone by LC/MS/MS as well as tests for 17 Hydroxy Progesterone, 11-deoxycortisol and other relevant hormones to rule out other disorders and diseases.

Dedicated Endocrinology Laboratory

Quest Diagnostics Nichols Institute was among the first reference laboratories to embrace Mass Spectrometry as the reference method for steroid quantitation. Many of our hormone tests rely on LC/MS/MS for superior sensitivity, specificity, and precision.
