B -- Serological Test for the Detection of Anti-diphtheria Antibodies

The Centers for Disease Control and Prevention (CDC) plans to issue a sole source purchase order worth $35,000 to the Health Protection Agency (HPA) in the United Kingdom for specialized serological testing, specifically Vero cell intoxication neutralization assays aimed at detecting anti-diphtheria antibodies. This procurement aligns with FAR subpart 13.106(B) and is justified by the unique expertise and qualifications of the HPA, which is recognized internationally as a reference laboratory and maintains clinical pathology accreditation. The HPA serves as a World Health Organization Collaborating Centre for Diphtheria and Streptococcal Infections, positioning it as a leading authority in this field and a trusted partner for such specialized tests. The contract is identified under solicitation number 0000HCJ3-2005-23808 with NAICS code 541380, indicating professional scientific and technical services. The CDC does not identify other providers within the United States capable of delivering this specialized assay, underscoring the sole source nature of this order. The points of contact for this contract are Ronnie E. Francis and Sherry A. Smallwood, both contract specialists at the CDC, with contact primarily through email as telephone calls are not accepted. This contract supports critical laboratory analysis integral to public health surveillance and response activities related to diphtheria antibody detection.
