Just open the wrapper the strip is contained in and remove the plastic cover on the tip. Get a good, well-hydrated, mid-catch sample, then place the strip into the urine so that the test tip is submerged to the marked line but not above. Allow 1-2 minutes for the urine to travel up the strip. The C line at the top should be a bold line to confirm that the urine traveled up the entire strip. The T line is for the test itself. Any sort of faintness here represents a passing test. If you require further help or interpretation of a strip feel free to contact us at the email address or phone number below.
