How much blood do they draw for doping test

Does anyone know how many ml of blood does doping controller draw from a rider to perform the blood tests.

Would the amount of blood drawn prior to a difficult stage affect a rider during a difficult climb, like would he loose some of his power?

Lets say if they draw 7ml of blood, that's like 1% of blood in the body, does that make a difference?

Good question...one of many similar I have pondered.

I have assumed the amount to be <5ml...but I don't know.

5ml would make a difference but so small as to be hidden within the "noise" of experimental error (IMO).

Allied to this was: If athlete is on EPO then there are injections...how are the multiple needlestick wounds hidden to avoid detection...given that injections are banned except under exceptional circumstances (which would presumably require certification?)?

Here in the clinic, we know that people wear long socks to hide needle marks in the ankle. And presumably, really really long socks to hide needle marks in the arm.

Sticking a needle in yourself isn't a prohibited activity, nor is it necessarily a sign of doping. There's no reason to try to avoid detection.

Since long socks are a thing, if someone wants to conceal something in their ankles, they'll use them. Same with tattoos. And there's always make-up. It's not some sort of conspiracy theory.

Heroin junkies taught them this trick. So many similarities to PED junkies and heroin junkies. So many.

if you watch the CSC movie 'overcoming' riis is taking little vials of blood from the rider's thumbs in one scene where they stop in the middle of a training ride on the side of the road (lol)

a proper doping control takes only a small amount more than is seen in that film

ie, about 5 or 6 drops worth of blood total

Thats a lactic test. Only needs a ***.

Sounds a bit anemic, doesn't it? Total of .7 ltrs of blood?

If indeed they take as much as 7 ml we're down at about .1% - basically at homeopathic levels here...

If on the other hand they were real vampires and took a proper gulp out of the riders, then we're talking - but not sure anybody's claimed that yet...

WADA guidelines relating to doping control activities.

http://www.wada-ama.org/en/Resources/Model-Rules-and-Guidelines/Guidelines/
 
From the WADA guidelines

2x3 ml for whole blood analysis

2x5 ml for serum type analysis

1x3 ml for Bio passport (no B sample required)



"Average adult" has 5000 ml of blood
10 ml is 0.2% of that blood volume

An endurance athelete would likely have a higher volume than average.
