Are USADA results based on a passport?

I have read that there are those that argue for and against the passport system, so is USADA testing based on a passport, or like system?

The passport is a method of setting a baseline of tests, and is supposed to be able to tell if you have ever used steroids subsequent to the creation of the baseline.


Edit -

"An athlete biological passport is an individual electronic record for professional athletes, in which profiles of biological markers of doping and results of doping tests are collated over a period of time. Doping violations can be detected by noting variances from an athlete’s established levels outside permissible limits, rather than testing for and identifying illegal substances."

whut?

 

I think EPO can only be detected through use of the 'blood passport', so I'd assume they use it. But that's all assumption based on information from the time Lance was passing all his tests.

 

Ok, that's exactly what I was wondering. I have read a number of articles questioning the effectiveness and accuracy of the passports, so wondering is TJ will go down that path. Thank you for that!

 

wat

 

Ha, I thought I might do a bad job of explaining it, based on my rudimentary level of understanding on the subject, myself. But, if you see @iwhoopedbatman 's response, it might do a better job than I did.

 

Please don't just take my word for it though. That is all memory from years ago and assumption. One moment:
@-Dim-, answer this sherbro's OP.

 

all good

 

Moved to OP

 

Edited the OP, maybe that will help

 

I got so many stamps on my biological passport I'm a biological traveling fool

 

sounds like it makes sense with PEDs that occur naturally but can vary a lot in individuals like testosterone
ie. if you've always been at about 500 then one day you're at 1500 something ain't right

 

maybe they just ate a superfood

 

or reached their final form

 

they have urine and blood passports.
