For example, at the 2004 Athens Olympics, the laboratory receive
2926 urine samples and 691 blood samples [5]. Some federations, such as Union Cycliste Internationale
collect blood before races for health tests (not doping-control tests), and athletes with atypical values
deemed medically unsafe (eg, high hematocrit) are not allowed to compete [6].

Testing urine is better than testing blood for most prohibited substances (small molecules, molecular
weight less than ~800 atomic mass units). Urine collection is noninvasive and yields a large volume of
sample, with higher drug concentrations than in blood and with far fewer cells and proteins to complicate
extraction.

And here is Q&A with Dr. Don catlin who heads anti doping research. This is another blood-urine debate that relates to EPO

Dr. Catlin does doping test for a living...
In the Olympics, blood is collected but not as much as urine, but at least they collect it. We are talking about Boxing here. In Boxing, only urine tests are conducted and they are not even random. You have to be an idiot to fail a scheduled urine test....

Urine test is good for MOST prohibited substance, NOT ALL
... Key word "MOST", not "ALL"... show me a urine test for HGH and I will show you a Unicorn. Scientists are currently working on a urine test for HGH and it will take them a couple of years to develop it. By the way, HGH is not the only Perfomance Enhancing Drug out there. There are tons of others, some that can be detected through only urine, only blood, both, bone marrow sample or none of them...
