Has anyone recently had Car-T using Carvytki? If so, how long did it take for your cells to come back, after collection? My cells are coming back this week. They were collected on March 20th, so 8.5 weeks. Chemo next week, then into the hospital Memorial Day weekend. I recently received my cells and spent 2 weeks in the hospital. I am now having some issues with ortho static blood pressure. Has anyone else experienced this?
