Hello

 

I need help in TTI screening test for blood donors   we observe variation in results between full automation machines although they processing in the same methodology for example Architect and Vitros machine some samples reactive for anti-HCV on Architect machine and negative by Vitros machine, and some samples are positive by Vitros machine and negative by Architect, so in this situation which machine considered as accurate to use for screening test for blood donors.

 

Thank you

are you sure that the vitros testing is approved for donors?  the donor testing algorhythms are different than those of routine hepatitis testing.  I would bet that that is the reason for your variation.
