The National Institutes of Health (NIH) intends to issue a sole source firm fixed-price purchase order to CareDx Lab Solutions Inc. for the procurement of Allo Seq Tx17 Next Generation Sequencing (NGS) reagent kits. This acquisition aims to secure a one-year supply of NGS reagents necessary for the Human Leukocyte Antigen (HLA) Laboratory within the Department of Transfusion Medicine, ensuring adequate stock for patient testing through quarterly shipments scheduled from November 2024 to August 2025. The HLA Laboratory plays a critical role in providing diagnostic testing and consultations for transplant eligibility, maintaining accreditation, and engaging in research for new diagnostic tests.
