This requirement is for a service agreement to support an existing FibroScan 430 Mini+ Package at the National Institutes of Health Clinical Center, used for both clinical patient care and clinical research. The agreement is needed to ensure continued operation, proper calibration, and reliable performance of the system. Maintenance, calibration, and repair must be performed according to the manufacturer’s specifications, as only the manufacturer has the proprietary knowledge, tools, and procedures required. No other vendor can be used, as alternative service providers could cause improper calibration, equipment malfunction, or loss of data integrity. The location for performance of services is the National Institutes of Health Clinical Center.
