Each Rapid Drug Screen Card is individually packaged in a foil pouch to ensure its integrity. Just fill in the patient ID area, the operator and the date; remove the protective cap; and immerse the test strips vertically in room-temperature urine (at least halfway) for 10–15 sec. ; remove from sample and lay flat for 3–5 min.; read results right away. You can have results in less than four min.! Choose from One-Panel, Two-Panel, Three-Panel, Five-Panel, Six-Panel and Nine-Panel Cards.
