How accurate are the blood tests done at hospitals?

My friend crashed their car while they were barred out ( Bliss Bars :) ) a while back, and they said that when they were taken to the hospital, they were told that there was no alprazolam in their system; only barbiturates. (???) I don't see how that could be possible because you would need a much higher dose of much more expensive and harder to find powder than alp in each bar, and with as many as they took, they would have been dead, had the bars actually contained a barbiturate.

And then a few months ago, when I crashed my car while barred out, the blood test showed that I had only marijuanas, heroin, alprazolam, MDMA, and cocaine in my system, but I never did any coke? at least I don't think I did??? Maybe it was in the heroin or something, idk; but these two occurrences seem very odd to me.

Thoughts?

So is crashing your car a common occurrence with xanax? Seems a lot of stories about bar users involve them crashing their cars.

You act proud of all the drugs they found in your system, yet take issue that cocaine was found that you don't remember ingesting? That's your takeaway from this situation? That the hospital made an error inventorying the drugs in your system? Not, hey I really fucked up because I operated a motor vehicle after I did a bunch of drugs and endangered the lives of innocent people and maybe I need to examine my waste of a life? Nope, it must be someone else's fault because their testing was flawed. Is this some kind of half baked defense you're trying to cook up to tell the court, and I really hope you have to answer to a judge for being such an irresponsible moron, and that he revokes your license so you have to walk to your job at McDonalds.

All drug tests are assaying for the metabolites of drugs not the actual drugs themselves so many drugs will show false positives or negative for totally different drugs. It depends on how the drugs you were taking metabolized in your body. There's usually more than one route of catabolism for all substances that enter your body, this explains why some some drug tests will show false negatives. But false positives I can only speculate that two different drugs may lead to similar metabolites. But no matter the results, the dip stick tests that hospitals use are 'presumptive' test not conclusive. It takes $$ and time to a complete a conclusive toxicology assay via GCMS, and this is almost exclusively done only if you committed a crime that resulted in someone other than you being injured ie DUI with serious bodily injury.

Not hugely accurate. Nurses don't seem to find them very reliable in my experience.

I dropped after taking a heap of xanax & endep to kill a meth comedown. When I came to I was feeling self conscious about admitting id taken meth. The nurse said id tested positive for meth (no mention of the pills). I said 'i haven't taken meth in years'. She agreed with me and said the test was most probably wrong.

Second time i was taken into hospital by police after taking too much valium and endep. This time I was being belligerent when I woke up. The nurses told me id overdosed on xanax. I hadn't had any xanax for a month or so and i told them that. They refused to accept that (not believing the word of a problem drug user? How dare they). They insisted id OD'd on alp not diazepam.
