The National Institutes of Health (NIH), specifically the National Institute of Allergy and Infectious Diseases (NIAID), intends to negotiate a sole-source contract with Antech Diagnostics, Inc. for one year of diagnostic laboratory testing services at the NIH Animal Center in Poolesville, Maryland. The required services include clinical pathological evaluations of blood and other bodily fluids from non-human primates, encompassing tests such as Complete Blood Counts, Blood Chemistry Analysis, and Urinalysis, which are critical for ensuring accurate and timely results in research. This procurement is justified under the statutory authority allowing non-competitive procurement due to the necessity for continuity in laboratory services, and interested parties are invited to submit capability statements by January 23, 2023, to Calvin Robinson at calvin.robinson@nih.gov for consideration.
