Yes. This phenomenon is called background and happens because the conjugate/sample is continuing to migrate up the strip.Occasionally, some specimen attributes will cause a clearing of the conjugate/sample that is slower than usual. In these cases, you should allow the strip to continue running the full 45 minutes.The strip should eventually clear as the conjugate/sample is drawn into the wick. Results from test strips with background are valid provided the control line is present.
