Specializing in highly specific and sensitive endocrine testing services

We provide a unique service oriented to the distinct requirements of the practice of endocrinology. We are an industry leader in developing new, clinically relevant assays and establishing defined reference ranges for pediatric and adult patient populations. Our goal is to employ technology to provide useful clinical information—not just laboratory data—to positively impact patient care and the delivery of cost-effective medical treatment.

Storage for Repeat Testing

60-day frozen serum and plasma specimen storage allowing for add-on or repeat testing up to 2 months after the original blood draw date.

Multiple Specimen Protocols

Protocols to accommodate multiple specimens for stimulation testing and diagnostic profiles.

Preprocessing for Accuracy

Quantitative specimen volume analysis performed prior to testing to ensure sufficient specimen volume. Processes, including extraction, to purify specimens prior to testing.

Pediatric Testing

Pediatric volumes available for many common tests. Assays developed specifically to aid in the diagnosis of endocrine disorders common among pediatric patients. Some reference intervals are age-specific or by pubertal Tanner stages.

Specialized Methodology

Methodologies, such as HPLC/MS-MS, to measure low and abnormal hormone levels.

Scientific Experts

Direct access to scientific experts who specialize in endocrinology testing, with PhD-level scientists available to discuss assay methodologies and MD-level consultations available to discuss patient cases.
