What should I do if I get a test result that I didn't expect?

- Check that the test kit chemicals are in date. The expiry date can be found printed on the top of the reagent bottles.

- Check that you have followed the instructions exactly. If the instructions say a result should be viewed after 5 minutes, or a tube should be shaken for 1 minute, time yourself to ensure you are accurate. 

- Check that you are viewing the colour result in daylight, with the test tube touching the white part of the colour card.

If you have followed the instructions and the bottles are in date, the result will be accurate.
