How to Read the Result Windows
- Negative:Â Both the control line and test line appear. A faint test line is still interpreted as negative.
- Preliminary non-negative:Â The control line appears, but the test line does not appear for that assay.
- Invalid:Â The control line does not appear. Repeat the test using a new device.
For additional interpretation guidance, see how to read a drug test cup. Preliminary non-negative results should be confirmed using an appropriate laboratory method.
