No. Each of the lines may vary in intensity from one another. At the final read time (see product insert), check to see if you can see a reddish-pink/purple line of ANY intensity (faint or dark) across from the drug. If it is present, then the result for that drug is NEGATIVE. If no line is present at the final read time, the screen result is NONNEGATIVE (presumptive positive) for that drug. Reminder: for the drug screen to be "valid", the CONTROL line (CTL) must also be visible.

At the final read time (see product insert), if you see a "white line" against an overall light pink background for the entire strip—the result is NONNEGATIVE (presumptive positive) for that particular drug. The Control line (CTL) must also be present to be valid.

We recommend that you verify that each new shipment of product received, is working correctly at the time of receipt and on a monthly basis thereafter. This can be done by running a known NEGATIVE and known POSITIVE external quality control sample. MEDTOX has controls available for this purpose (see below). If a control is not available (you’re off site, etc), a quick way to verify product performance for a negative urine is to run a urine sample from yourself or other staff member that is known to be NEGATIVE. Follow the appropriate product insert directions for sample volume to apply, timing and reading. Note: do not substitute water or other liquid for the urine sample. If the product is not performing correctly, please contact technical support.
MEDTOX Negative Urine Drug Screen Control # 101183
MEDTOX 300 Positive Urine Drug Screen Control # 101830 (Use for all products with an OPIATE 300 cutoff)
MEDTOX 2000 Positive Urine Drug Screen Control # 101829 (Use for all products with an OPIATE 2000 cutoff)
Note: All other constituents in the POSITIVE controls are the same—only the opiate concentration is different.

No. The intended use is to detect codeine and morphine. Oxycodone is a synthetic opiate which does not cross react well with the current antibody. See the product insert. MEDTOX Laboratories can perform testing for OXYCODONE and OXYMORPHONE.

No. Propoxyphene is a synthetic opiate that is not detected with the opiate (morphine) antibody. There are several MEDTOX devices that are available that will screen for PROPOXYPHENE. Please contact your sales representative.

Yes, an OXYCODONE on-site screen was FDA 510(k)-cleared and is available in a number of different product configurations. Please call your sales representative for configurations and pricing information.

Yes. There are numerous studies that have shown that poppy seeds can contain enough morphine to trigger a positive opiate screen. This is especially true at the 300 Opiate cutoff, but may occur at the higher 2000 Opiate cutoff also. A single poppy seed bagel or bun may contain enough morphine on the poppy seeds to be detected in a urine screen performed on the same or next day after consumption. Confirmation is required to determine the concentration of morphine and codeine if any. No 6-MonoAcetylMorphine (6-MAM) should be present. The presence of 6-MAM is indicative of heroin use.
