PRINCIPLES OF THE TEST
Use fresh urine specimens. Urine specimens do not require any special handlingor pretreatment. It is best to test urine specimens immediately after collection.

In the absence of any drug in the urine specimen, the colloidal gold-labeled
antibody complex moves with the urine by capillary action to contact theimmobilized drug conjugate. An antibody-antigen reaction occurs forming a visible

line in the test area. Once the control line is visible, the test is ready to be read;
typically this occurs in 3-5 minutes.

LIMITATIONS OF PROCEDURE
The assay is designed for use with human urine only.
RapidOneTM OXY provides only a preliminary qualitative test result. Use a
more specific alternate quantitative analytical method to obtain a confirmed
analytical result. Gas chromatography/mass spectrometry (GC/MS) is the
preferred confirmatory method (1). HPLC may be used as the confirmatory
method for tricyclic antidepressants. Apply clinical and professional
judgment to any drug of abuse test result, particularly when preliminary
positive results are obtained. (2).
Other substances and/or factors not listed may interfere with the test and cause
erroneous results, such as adulterants, procedural errors or cross reactivity with
other drugs or agents. Refer to the Performance Characteristics section for more
information. If adulteration is suspected, obtain a fresh urine specimen and
Interference and cross reactivity studies were performed by testing the drug
analytes in the RapidOneTM OXY device with various other drugs. Below is the
list of drugs that will give a positive result at or above the concentration stated. All

urine. Ten (10) determinations were made at each serial dilution of

No immunoassay that produces a single response in relation to the
presence of multiple components in a mixture can reliably quantify
the concentration of these components. The Rapid OneTM OXY test
