The Red Cross may know. Try them. Sometimes there are ads in the Daily News and LA Times.

Because of recent state legislation concerning the safety of blood transfusions, there are no long published lists of private blood processors either on the Net or otherwise.

So, you may be out of luck as a potential blood donor.

Good luck!
