Has USADA ever found that the initial positive test was wrong?

[mommas homeboy]

I hear the words "flagged for a potential" doping violation but don't know exactly what that means.

Has it ever happened that a potential doping violation was a mistake somehow? Also, could his A sample be positive while his B sample is negative?

 

[trident]

They are all mistakes..... by the fighters and their camps

 

[SENDOSMASHER]

The most likely scenario for Jon Jones is this:

Sample A shows up the traces of T-Bol
Sample B shows up clean with no traces of steroids... but cocaine metabolytes

This scenario would not surprise me

Someone said on here that Yoel was the exception to this rule, with his B sample being clean but I'm fucked if I know how he did it

 

[Combat Wombatt]

Isn't that what happened to Cyborg?

 

[bobafett]

Yoel is the only one I can think of off the top of my head.

Romero got off because they found the substances in the supplements he took not because his samples came back different. He still got a 6 month suspension for it. He wasn't cleared for doping. He was ruled to be negligent but got a break because of the supplement defense. No different than Anderson and Jones's "dick pill" excuses.

His B sample returned positive too.

That's not what happened in Yoel's case. It's called a potential violation because they're provided due process to try to provide a valid excuse, etc... I don't see that happening here.

I think she got a retroactive therapeutic use exemption

The most famous athlete I can think of who's B sample came back clean was Olympic Sprinter, Marion Jones.

She was guilty as hell too and later admitted it and had to return all her medals.

It wasn't clean. A lot of bullshit came out of ATT (via entimports) just after he failed. Both samples came back positive for ibutamoren.

In your medical experience
If I take some ibutamoren, will I get YOEL like traps?

In mma ?not that im aware of,in general?yes there was some girl olympian the other year who flagged for some prohibited substance,turned out it was from her water supply so they gave her a pass,i believe there has been similar incidents with tainted meats

 

[Wariowokecancel]

Maybe twice in history but that probably means that the detection threshold was set too high.

Stop clinging to straws, Jones is suspended and stripped.

 

[mb23100]

How much time in between taking the two samples? Do they take them at the same time?

 

[SpedDaddyV]

next minute, shit im finished, she'll be flaggin it home
but i always keep a straggler, thats known to bone
and run through a lap, faster than marion jones
man listen, i still got them grams flippin tan pitchen,
corner to the damn kitchen
gained a couple fans having made the transition
but im still in the hood like a transmission
no cat can match me, i'm passin fastly who half as nasty

it is rare, but can happen.

I recall Cung Le's sample had issues. I don't recall other specific instances, but there's obviously a reason for taking two samples.

 

[Holic]

The only one I know of who actually got cleared after a positive flag was Cung Le, and that wasn't a U.S. lab. Plus he raised absolute hell over it.

 

[Pacemaker Joe]

Yes, there have been false positives from WADA labs, or cases where the A sample showed a positive and the B didn't. There are a few reasons this could happen

-the lab fucks up and reports a false positive. They detected something that wasn't there. This is rare, and labs have lost their accreditation over this before.

-the DCO or athlete fuck up, and contaminate one of the bottles during the sample taking process. This should be hard to do, and there's no reason someone would try. I'm not aware of any cases of a DCO fucking with an athlete due to corruption or anything like that.

-for some PEDs, the markers may deteriorate over time in the sample bottle, and so the A sample could show a (valid) positive, and the b show a (valid) negative, simply because molecules the lab was trying to detect weren't there anymore.

All cases are rare. If you gamble, placing a bet on the B sample matching the A is a safe bet, even at huge odds.
