The temperature requirement of a reagent card of the dry type fluorescence immunoassay analyzer is high, and the accuracy and the repeated consistency of a measurement result can be ensured only by keeping the temperature within a certain temperature range. The reagent card of the current dry type fluorescence immunoassay analyzer must be inserted into an incubator for temperature control before use, and the temperature of the reagent card reaches the required temperature range.
