    How to interpret the results

    How do I know if the test result is positive, negative, or invalid?

    A cassette from the Siemens Healthineers CLINITEST Rapid COVID-19 Antigen Self test showing a positive result, with red lines next to both the C and the T

    Positive

    If the test looks like this, then protein from the virus that causes COVID-19 was detected in the sample.

    The test is positive if there are two pink/red lines present, one at the Control "C" line and one at the Test "T" line. Look very closely for a line next to "T". This line can be very faint.

    Any visible pink/red "T" line is a positive result when the "C" line is also present.

    A cassette from the Siemens Healthineers CLINITEST Rapid COVID-19 Antigen Self-test showing a negative result, with a redline ONLY next to the control line (C)

    Negative

    If the test looks like this cassette, then protein from the virus that causes COVID-19 was not detected.

    You will only see one line visible next to “C” and no line visible next to "T".

    2 examples of invalid results on CLINITEST COVID-19 tests where one shows no red lines next to C or T and one where there is a red line next to T but not next to C

    Invalid

    If the test looks like either of these two test cassettes, then the test was not able to give a result and you must repeat the test with a new swab, a new tube, and a new test cassette.

    The test is INVALID if there is no line next to "C".
