Once you have followed the manufacturer's test kit instructions for use which will be included with your test kit your cassette will process your sample.
In order for you and the Consentry app to read the test result you will need to see a control line (a horizontal line that will appear next to the C position). If this does not appear your test is invalid and you will need to use another kit to provide a new sample. If you see a horizontal line in the T position only (no line in the C position), the test is still invalid.
Below are approximate guides for reading your results. These are illustration only, so please refer to your manufacturer instructions for instructions specific to your test kit.
