Read what I posted a few times
Ask someone for help afterwards if you still cannot grasp it
Done conversing w you. You have no agenda except to come in and slam me while having. apparently, a serious reading comprehension issue.
Take care
Bayhawks is correct. I'm guessing you're maybe getting confused when what you posted is talking about "splitting the sample In half".
The NFL takes a sample and splits it into A and B. That isn't the sample splitting the article refers to. That is still to come.
The A sample is sent to the lab and subjected to the two step test. The A sample is split in half at the lab and the first half has the the immunoassay test done on it. For Gordon that was a fail with a 38 when the threshold was 20. Then the second test is done on the other half of the A sample and the 16 was returned, over the threshold of 15.
That is the process outlined in your post. In addition to the testing guidelines in your post, for a failed testthe NFL will also, at the player's request, send the B sample to have confirmed it shows any evidence of THC. It isn't a failed test until both steps are done. That means sample B never comes into play until after the two step test is finished and was a failure. The NFL testing policy does not require the B sample to be over the threshold.
This is pretty much all a repeat
of my post recapping for someone what tests were done. Only thing added here is I highlighted that the two step test was performed on sample A. It did not have half of it performed on A and half on B. The two step test was conducted and judged a failure and Gordon informed. After that, Gordon has to request that the B Sample have the test done on it or it is never tested.
