The Albuquerque Area Laboratory Programs seeks to lease iSED Elite and miniiSED analyzers for one year under a firm fixed-price contract of $58,875.00, which includes equipment, consumables, annual services, and freight. This sole-source acquisition is justified by an unusual and compelling urgency to prevent disruption of essential Erythrocyte Sedimentation Rate (ESR) testing. The contract is needed immediately to ensure continuity of patient care while a long-term contract is developed. Performance of services is for federal laboratory facilities within the Albuquerque Area. A delay would risk discontinuation of in-house ESR testing, adversely impacting clinical operations.
