Test your Blood instead of Urine

Is it possible to give blood instead of Urine for a atheletic commission drug test? It would seem to me this would be a more accurate way of testing.

In some competitions mostly endurance. There is a check of Hemoglobyn, Reticulocyte and erh cant remember the third one. To look for elivated values. If there is an elivated value you are asked to preform a urine test.

Also blood tests are preformed in different ways there is bloodplasma or regular depending on HGH test or not.

how about stool?

isnt blood testing alot more expensive?

I think its the other way around. It depends on what type of analysis you are doing though.

I think in Sherks case he might want to request it. I am still on the fence.

what if there is blood in ur urine?
