How to read your test result
Positive test – course of action:
The test is positive when you have two lines visible.
The line in front of C shows that the control worked.
The line in front of Ag shows that COVID-19 virus has been detected.
Observe local COVID-19 regulations.
Negative test – course of action:
The test result is negative when you see a clear line in front of C only.
If your test is negative, BUT you experience symptoms of COVID-19, or you have been in close contact with someone infected with COVID-19, you should observe local COVID-19 regulations.
Invalid test – course of action:
If the test does not work as it should (e. g. by not developing a line in front of C), the test must be considered invalid. Try taking a new test. If you get the same result, please contact us via the form at the bottom of this page.
