These devices are intended to be used by healthcare professionals only. For in vitro diagnostic use. Measurements obtained by this device are used in the diagnosis and treatment of use or overdose of the drugs listed above. This assay provides only a preliminary result. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. To obtain a confirmed analytical result, a more specific alternate chemical method is needed. Gas chromatography/mass spectroscopy (GC/MS) is the recommended confirmatory method. | Prescription Use X<br>(Part 21 CFR 801 Subpart D) | | AND/OR | Over-The-Counter Use | (21 CFR 807 Subpart C) | |-----------------------------------------------------|--|--------|----------------------|------------------------| |-----------------------------------------------------|--|--------|----------------------|------------------------| Kacy Phillips Division Sign-Off Office of In Vitro Diagnostic Device Evaluation and Safety 510(k) K050024 page 1 of 2 {5}------------------------------------------------ ## (PLEASE DO NOT WRITE BELOW THIS LINE-CONTINUE ON ANOTHER PAGE IF NEEDED) Conqurrence of CDRH, Office of In Vitro Diagnostic Devices (OIVD) Terry Phillips Sign-Off Vie of In Vitro Distgroup of Device ruation and Sal.
