The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a sole source contract to Laboratory Corporation of America (LabCorp) for laboratory testing services at the NIH Clinical Center's Department of Pediatrics. The primary objective of this procurement is to measure 11-oxo-androgens, which are critical biomarkers for adrenal disorders, as LabCorp is the only laboratory capable of providing this specific testing panel. This acquisition is vital for maintaining the integrity of ongoing clinical research protocols, particularly for genetic testing related to congenital adrenal hyperplasia (CAH), which has been conducted with LabCorp since 2004. Interested parties may express their interest and capabilities to Kristin Nagashima at kristin.nagashima@nih.gov by January 5, 2026, at 12 PM EST, although the government retains discretion over the decision to compete the requirement.
