Unanswered: What are the causes of Benzo false positives?

AFOAF has been testing positive for benzos in his urinalysis, even though he hasn't taken them in over a year. His doctor is adamant that there is nothing which causes a FP for benzos and I am inclined to agree as I can't find any info on this.
Ayone know what is causing this.

Some ideas:

High concentrations of Diphenhydramine can potentially cause a false positive for benzodiazepines with laboratories that screen by enzyme immunoassay. Diphenhydramine is found in some sleep aids. Examples are Tylenol PM, Excedrin PM, Unisom and many others.

Oxaprozin a non-steroidal anti-inflammatory drug, can also cause a false-positive for benzodiazepines on urine "drug abuse" panels.

Valerian is reported to cause false positives with some tests

There have been case reports of Sertraline causing false positives.

Depending on the test used changes in pH can also cause false positives (TPDA is notorious for this although she is unsure whether this test is still in use) Here's a link:

Just ask your FOAF's doctor to google "False positive for benzodiazepines". When SWIM did it she got 193,000 citations!

In all disputed cases you should ask for confirmation of test results with Gas Chromatography/Mass Spectroscopy.

SWIMs on Stillnoct but the doctor says that there is no way they could be causing it She does not have a PC so do you have a link to something I could print out and show her? I can't find anything about Ambien false poitives.
Thanks

SWIM's bad, the Ambien data was old (and so were the tests!). Original post edited accordingly.

Can't SWIY say that you've been using valerian? Or that you took some anti-inflammatories?

A link for NSAIDs: http://www.ncbi.nlm.nih.gov/entrez/q...=pubmed_docsum

http://www.ncbi.nlm.nih.gov/entrez/q...=pubmed_docsum

SWIY's doc should certainly be able to access the original articles/data of those links through her organisation.

SWIM's having trouble linking the valerian thing (she'll try again)

Is it possible to get some sort of doctors reference explaining this ? I've searched everywhere ! False positives seem to be a touchy opinionated subject . Trying to prove someones innocence ...
