FAQS
The shelf life of in vitro diagnostic reagent varies significantly depending on the specific reagent, its formulation, and storage conditions. Generally, reagents are stable for 6-24 months when stored as directed by the manufacturer – usually at refrigerated or frozen temperatures. It's crucial to check the expiration date printed on the reagent packaging and to adhere to recommended storage guidelines to ensure optimal performance and accuracy. Expired reagents can yield inaccurate results and should not be used.
Proper storage is vital to maintain the integrity and effectiveness of in vitro diagnostic reagent. Most reagents require storage at 2-8°C (refrigerated), while some may need to be frozen at -20°C or lower. Avoid repeated freeze-thaw cycles, as this can degrade the reagent. Protect reagents from exposure to light, heat, and humidity. Always refer to the manufacturer's instructions for specific storage recommendations, as these may vary.
Implementing robust quality control measures is essential for reliable diagnostic results. This includes running positive and negative controls with each batch of tests to verify the reagent's performance.
