  1. Any one using this kit and have been getting false positives? On occasion at the ten minute mark{completion} the control is showing a definite pink minus sign, but the migration line that creeps up towards the top will flag a positive for A or B even when there is no definite pink line parallel to the control, on repeat testing the result will be negative. If the test strip is read some time after the migration line has moved up it will be negative but it is not in protocol to read it past the ten minute mark...thanks Norm
