A statement of warnings or precautions for users as established in the regulations contained in 16 CFR part 1500 and any other warnings appropriate to the hazard presented by the product; and a statement “For In Vitro Diagnostic Use” and any other limiting statements appropriate to the intended use of the product. The limiting statement appropriate to the intended use of a prescription in vitro diagnostic product shall bear the symbol statement “Rx only” or “℞ only” or the statement “Caution: Federal law restricts this device to sale by or on the order of a ___”, the blank to be filled with the word “physician”, “dentist”, “veterinarian”, or with the descriptive designation of any other practitioner licensed by the law of the State in which the practitioner practices to use or order the use of the device.

For a reagent, appropriate storage instructions adequate to protect the stability of the product. When applicable, these instructions shall include such information as conditions of temperature, light, humidity, and other pertinent factors. For products requiring manipulation, such as reconstitution and/or mixing before use, appropriate storage instructions shall be provided for the reconstituted or mixed product which is to be stored in the original container.
