who actually is testing my sample labcorp or choicepoint?

I looked at my sheet that they gave to me, and it shows Labcorp and than for MRO it has CHOICEPOINT some place located in California?

so who is actually testing the sample? Is labcorp the collector and than sending it to choicepoint? or is labcorp collecting and testing and if something aint right it goes to Choicepoint?


btw i subbed with magnum synthenic..

Labcorp will be doing the testing
