It’s important to carefully follow the instructions and wait the recommended amount of time between each step. Proper timing allows the semen sample to liquefy so it can flow correctly through the test device. If the timing isn’t followed, the sample may not pass through the device properly, which can lead to an invalid result.
If your result is invalid and no control line appears, we recommend retesting while following the recommended timing guidelines, as timing can sometimes affect the result. You can also submit a support ticket, and our team will assist you with the next steps.
