Cryopreservation Lab
Enough stem cells need to be collected to quickly regenerate your bone marrow after they are injected, so that more than one pheresis treatment is needed. At the end of each daily collection, the stem cells are sent to the cryopreservation lab for testing, preparation for transplant and storage. The cell count of the day's collection is usually available 3-4 hours after the completion of the pheresis collection.
