The testing protocol is designed for efficiency: simply dip the strip for 3 seconds and read the results after 90 seconds.

Once opened, the test strips are effective for 6 months. There is a convenient ‘Date Opened’ tracking field on the bottle label to help you manage this timeframe easily.
Is it easy to interpret the results?
