Objective To establish the 3rd of national standardized prodocts for quantitative immunoassay of Thyroxine(T4) in China. Method and result High purity of T4 raw material were precisely weighted to prepare 2000ng/ml solution with 0.02M PBS buffer containing 1.0% BSA, then sterile filtered, filled and lyophilized to prepare the natuonal standard candidate. The candidate was calibrated collaboratively using 2nd national standardized products as standards(150551-0004). The immune activity of candidate was 940ng/ampoule. Conclusion The candidate met the relevant requirements and can be served as the 3rd of national standardized products for quantitative immunoassay of T4. The establishment of the 3rd of national standardized products for quantitative immunoassay of T4 will provide a quantitative basis for quantitative immunoassay kits of T4.
