When refrigerated at 2-8°C, unopened positive pregnancy test positive clinitest hcg controls are stable until the expiration date. Once opened, they remain stable for 31 days or until the expiration date, whichever comes first. If stored at room temperature (18-25°C), they are stable for 31 days or until the expiration date, regardless of when they were opened. Proper storage is crucial for maintaining the product's effectiveness and ensuring reliable test results.
