My vet offered me a voucher she git from the manufacturer of Prascend that entitled me to free testing.  I paid for the vet visit, and draw, and she then sent the frozen sample to IDEXX,  I believe.  She claimed IDEXX sent it along to Cornell.  Or at least somehow this was a Cornell test.  Is anyone familiar with how this works?  Is my sample really being double shipped.  I could ask my vet, but her memory may well not be reliable, and it was some time ago.
