Propoxyphene Drug Test

Propoxyphene is an opiod with chemical similarity to methadone and used as an analgesic. They mainly act by blocking the opiod receptors that carry pain signals to the brain. But they have additional effects like producing euphoria. Though initially started as an analgesic, they progressively cause drug dependence and produce harmful effects. It is largely due to the tolerance gained by the system against the drug. Finally they lead to addiction resulting in severe withdrawal symptoms. Propoxyphene drug test is lateral flow Immunochromatographical assay for the qualitative detection of propoxyphene and norpropoxyphene in urine.

Darvocet is the prescribed name for the generic name propoxyphene. They come in various preparations like tablets, capsules, and liquid forms. They are orally administered. The Immunochromatographical test is just a preliminary procedure. The confirmation has to be done by gas or liquid chromatography and mass spectrometry devices. The cut off concentration for propoxyphene is 300ng/ ml. darvocet drug test can be done using drug testing strips which contains anti-propoxyphene antibody coupled particles and propoxyphene protein conjugate.

The Darvon drug test strips come in round vials with desiccant caps and a package insert. In addition you would need a timer and a specimen collection container. The urine sample must be collected in specimen cups and stored at room temperature. The urine specimen must be collected in sterile containers and can be collected during any time of the day. The test strips come with an expiry date and must be kept sealed until use. They can be refrigerated but should not be frozen. Adequate attention must be given to avoid contamination of the samples.

Propoxyphene test is a one step process which is a simple one. The urine samples must be left at room temperature to be tested. Once the test device is opened, it must be used as soon as possible. Keep the test strip vertically in the urine and dip it for 10 to 15 seconds. Keep in mind that the test strip must be immersed only up to an optimum limit as indicated on the test strip.

The strip for propoxyphene testing consists of control lines. The test is considered valid only if the controls react to the specimen optimally. The result appears in 5 minutes which is accurate and is indicated by a color change. It is advisable to read the instruction manual carefully before getting on with the tests.
