Does anyone know how long it takes to get results from a blood test for Marek's? I took my Olive, a black sex-link, to the vet last Monday, July 25. As of today, eight days later, the vet still hasn't received the results. I'm fairly certain that it is Marek's. She has the classical splayed legs. We had a silver Sebright that came down with symptoms after her, and the Sebright passed away three days ago. The Sebright had one splayed leg and had difficulty breathing. There's just a part of me that holds on to hope that it is something else that is treatable. I thought results would take maybe 2 or 3 days at most.
