Floyds Testosterone Levels Below Normal? - Page 3

ROFL dude some people

I'm a chick, not a dude, but I'm glad I made you laugh

They are preparing to fight the test results. With the nominal testosterone values normal and the nominal epitest values being very low, giving a high ratio, they probably have a lot of possible explanations available. They want to keep all possible causes open.

From what I have read testosterone testing has a lot of problems, so much so that simply finding the ratio is not enough. You need a further medical investigation to rule out various natural causes. Every possible cause will be an opening for Landis' lawyers to attack the test results.

I have not been able to find any solid info on what would cause epitestosterone to be
nearly a tenth of normal. It may very well be that the validation of the testosterone test was not checked out against this situation. It seems to me that Landis' lawyers will have a lot to play with.

oops i mean dudette

[QUOTE=dasnootz]I just heard an interview where someone said that his testosterone levels were actually below normal, but his epitestosterone levels were even lower... creating an 11/1 ration of testosterone to epitestosterone above teh 4/1 legal threshold.

I don't know exactly the type of test involved in this case, but with most urine-based endocrinology tests the reason you use a ratio and not simply an absolute amount is because of alterations in hormone concentrations due to changes in urine concentration. If you only looked at urine cortisol, for example, a high value could indicate abnormal blood levels or simply that your kidneys are conserving water at a high rate, increasing the concentration of any chemicals not reabsorbed...in this case, cortisol. Using a ratio helps to normalize for any changes in hormone concentration simply due to changes in urine concentration. In the case of testing for cushing's disease with urine, cortisol:creatinine is measured.

If this reasoning applies to the Landis test (i'm not even sure if the test in question is a urine test or a blood test), it may be possible to have a low, normal, or high absolute urine testosterone concentrations with doping, but ideally all situations would still involve altering the ratio...not to say that other factors won't alter the ratio as well.

Don't take this as gospel, I'm only a vet student.

Don't sell yourself short. You have the makings of a great preparatore. With Fuentes out of business there is a huge opportunity in Spain. Eight million euros in three years is not chicked feed.

LOL! Quality stuff.

yikes! i didn't realize his "business" was THAT lucrative. i may need to take a little break after vet school and work on paying back the $100K+ in student loans that i'll owe.
