What is the recommended storage condition for unopened RPR antigen?

The recommended storage condition for unopened RPR (Rapid Plasma Reagin) antigen is 2-8 degrees Celsius. This temperature range is crucial for preserving the stability and efficacy of the antigen. At this controlled temperature, the biochemical properties of the antigen remain intact, ensuring reliable results when the antigen is used in testing for syphilis.

Storing the antigen at room temperature or above 30 degrees Celsius could lead to degradation or loss of potency, which would adversely affect test accuracy and reliability. Similarly, storing the antigen below freezing can also compromise its structural integrity, leading to false results. Hence, maintaining the antigen within the recommended temperature range is essential for the best practice in immunoserology and accurate clinical outcomes.
