Immunoassays for selected drug classes, e.g., opiates and benzodiazepines, are also subject to clinically important false negatives (2). False-negative results can be caused by a variety of factors including the cross-reactivity of the antibody used by the assay, the cutoff concentration for a positive result and.
While it is useful to understand some of the common causes of false-positive immunoassay results, in the majority of cases the cause of false-positive screening results is unknown. In practice, there are many cases where immunoassay positive results are not confirmed when analyzed with a more sensitive and specific technique. This review focuses on cases where the cause of a false positive is identified. Owing to the number of false positives, all immunoassay results are considered ‘presumptive’ until confirmed by an independent chemical technique.

Immunoassays are widely used to screen urine samples for recent marijuana abuse by detecting 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (11-nor-Δ9-THC-9-COOH), the major urinary metabolite of Δ9-tetrahydrocannabinol (THC) ( 7 ) ( Figure 2 ).
Several dogs from a single musher's team tested positive for the drug tramadol, a Class IV opioid pain reliever that's available by prescription only in pill, liquid, suppository and other forms. It's unclear how the dogs ingested the medication, or even if the musher, who the statement does not name.
In the letter, Musher X denies allegations that they administered the drugs to the dogs and “repeatedly offered to submit to a polygraph, and complied fully with all requests.”
The incident prompted the Iditarord to update its rule book to makes mushers responsible for proving their innocence, rather than the other way around, if their dogs are flagged with a positive drug tests.

Tramadol is an opioid, i.e., a synthetic product that has psychoactive effects through its actions on opiate receptors. Chemical structure of tramadol differs significantly from that of morphine but is a synthetic version of codeine and will show a positive on a drug abuse screening, so you should show them the.
