to false-positive and false-negative results. All positive and any unexpected negative res Casual dietary ingestion of poppy seeds does not cause a positive result for opi-oids on urine drug testing. Most studies suggest that gabapentin is highly unlikely to cause a 'false-positive' for any of the drugs being looked for on a standard 5-panel test due to its difference in structure and molecular composition. Drug screen false positive is reported as a side effect among people who take Gabapentin (gabapentin), especially for people who are female, 40-49 old, have been taking the drug for 1 - 6 months also take Oxycodone, and have Depression. Tested Positive For Gabapentin In our latest question and answer, the pharmacist discusses getting a false positive test result for gabapentin. Gabapentin, the generic name for Neurontin, is tested for in the same way as any other drug would be. The detection time for gabapentin in urine is 2 to 4 days after the last intake. A urine test will be positive if the test sample contains at least 2,000 nanograms of gabapentin per millilitre of urine. Gabapentin may produce a false positive result on certain 12-panel drug tests if it shares structural similarities with other compounds being tested for, such as morphine or oxycodone. Urine tests are more sensitive than saliva tests and can detect gabapentin for a longer period after ingestion. Neurontin (gabapentin) is not a medication that is typically associated with 'false positives' on most drug tests, including Suboxone (buprenorphine). It is not a reported/listed drug in most literature searches of agents that are most likely to cause 'false positives'. Can neurontin give a false positive for cocaine in a urine drug test? ## Neurontin contains the active ingredient Gabapentin, it is an anticonvulsant, which has also been shown to help certain types of nerve pain. False-negatives and false-positives from immunoassays can lead to adverse consequences for patients and providers. By identifying medications that contribute to false-negatives and false-positives, pharmacists decrease misinterpretations from urine drug screens. Hi mrs braum, There's also a possibility of a false positive. Medications like zoloft have been shown to cause a false positive for BDP. The link below, are the results of a two year study on false positives for benzodiazepines. Of the 522 test subjects, 160 were false positives. Whenever humans are involved in the collection, chain of custody, mixing reagents, reviewing findings, etc, there It does not typically show up on drug tests; however, it's important for employers and those administering drug tests to be aware of the potential for false positives when testing for certain drugs. Let's take a closer look at whether gabapentin will show up on a 12 panel drug test. Not Likely: It is unlikely that Neurontin (Gabapentin) will trigger a false positive urine test for drugs. However, if you are taking other medications then these medication may alone or in combination with Neurontin trigger a positive urine screen. I looked in multiple research articles on prescription medications that can cause false positives on drug screens, and gabapentin/Neurontin did not show up in the lists of any of these professional research studies. False-positive results for amphetamine and methamphetamine were the most commonly reported. False-positive results for methadone, opioids, phencyclidine, barbiturates, cannabinoids, and benzodiazepines were also reported in patients taking commonly used medications. Neurontin should not show up as a false positive for benzo. The chemical structure is sigificantly different than that of benzos. It is becoming more commonly tested for these days though since more and more people are using this medication recreationally. In our latest question and answer, the pharmacist discusses drug testing for gabapentin and what could cause a false-positive. Mr A had positive screening for opiates by day 4 of hospitalization in the absence of medications or foods that can produce a false-positive result. However, Mr A had negative testing of heroin-specific metabolites, which would have allowed for confirmation of the suspected surreptitious use. False-positive results Due to the potential for cross-reactivity associated with immunoassay urine drug screens, several prescription and non-prescription drugs have been reported to cause false-positive results. 2,6 In addition to medications, several other substances have been associated with false-positives, such as baby wash products, supplements, and food. False-positive drug screens are We observed similar chromatographic issues from high gabapentin levels, but additionally we observed an interference peak having the same m/z as amphetamine (m/z 136.1121). The interference passed all qualitative criteria for amphetamine leading to potential false-positive results. The search strategy was developed by a medical librarian combining the terms false positive results, urine, and substance abuse testing and the generic names of 116 medications.
