What is the duration of RPR antigen stability once opened?

The duration of RPR antigen stability once opened is 3 months. This means that after the RPR antigen vial has been opened, it remains effective and reliable for that specific period, provided it is stored under appropriate conditions. This stability is critical for ensuring accurate test results, as the performance of the serological test relies on the integrity of the reagents used.

Maintaining the recommended storage conditions and being mindful of the opened timeframe is essential in diagnostic labs to avoid false-negative or false-positive results, which could significantly impact patient management and treatment decisions. Understanding the lifespan of reagents like the RPR antigen helps laboratory personnel to plan their testing schedules and manage supplies efficiently, ensuring that tests are performed with fresh and stable reagents for optimum accuracy.
