Propoxyphene (PPX) Drug Abuse Test Kit PPX Rapid Test 4mm dipcard , cut-off 300ng/Ml
Propoxyphene (PPX) Drug Abuse Test Kit
The Propoxyphene Assay is intended for qualitative determination of propoxyphene in human urine.
This assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
Reagent Preparation and Storage The reagents are ready for use. No reagent preparation is required. All assay components, when stored properly at 2-8°C, are stable until the expiration date indicated on the label.
In the case of accidental spill, clean and dispose of material according to your laboratory’s SOP, local, and state regulations.
In the case of damaged packaging on arrival, contact your technical support representative (refer to back page of this PI).
DIRECTIONS FOR USE
Collect urine specimens in clean glass or plastic containers. Testing fresh urine specimens is suggested.
The Mandatory Guidelines for Federal Workplace Drug Testing Programs recommends that specimens that do not receive an initial test within 7 days of arrival at the laboratory should be placed into secure refrigeration units.
Samples within a pH range of 3 to 11 are suitable for testing with this assay.
An effort should be made to keep pipetted samples free of gross debris. It is recommended that highly turbid specimens be centrifuged before analysis. Adulteration of the urine sample may cause erroneous results. If adulteration is suspected, obtain another sample and forward both specimens to the laboratory for testing.
INTERPRETATION OF RESULTS
NEGATIVE:* A colored line appears in the Control region (C) and colored lines appears in the Test region (T). This negative result means that the concentrations in the urine sample are below the designated cut-off levels for a particular drug tested.
*NOTE: The shade of the colored lines(s) in the Test region (T) may vary. The result should be considered negative whenever there is even a faint line.
POSITIVE: A colored line appears in the Control region (C) and NO line appears in the Test region (T). The positive result means that the drug concentration in the urine sample is greater than the designated cut-off for a specific drug.
INVALID: No line appears in the Control region (C). Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for Control line failure. Read the directions again and repeat the test with a new test card. If the result is still invalid, contact your manufacturer.
A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
A side-by-side comparison was conducted using the PPX Rapid Test Cassette (Urine) and GC/MS. The following results were tabulated:
