1) That would be a fail test subject.
2) The DNA of jinchuurikis of 1-8 tails are not so special compared to Naruto, Karin, Juugo, Suigetsu, Sound 5, Orochimaru.
Also the chances for Oro to fail is 99.99 percent because his blood group isn't AB+
But Kabuto's blood group is AB+ and hence he survived all the blood samples injected into his body.
( For proof, read the manga where Oro, Kabuto and Sai stops at a river where Kabuto washes his medical instruments and talks about his blood group to Oro, even Oro finds interesting after hearing)
