First do not attach the collection bottle if you have placed the home test strip in flowing urine then depending on the test requirements; if it is first stream: place the strip in the flow coming out of the front of the device e.g. for Chlamydia, if its midstream place the strip in the flow coming out of the diverter, and if its last stream wait until you are about to stop voiding and then place it in the flow coming out at the front of the device.
If there is no requirement to place the strip in flowing urine you can attach the collection bottle and then if the test requires a midstream sample simply dip the test strip into the sample container which will contain the midstream.
