After thawing, single units of cryo (or units pooled using a sterile method) can be stored at 20–24 °C for up to 6 hours. If units of cryo are pooled in an open system, they can only be held at 20–24 °C for up to 4 hours. [3] Presently cryo cannot be re-frozen for storage after it is thawed for use if it is not transfused.
Thawed plasma is made from FFP or PF24 and kept refrigerated (at 1–6 °C) after thawing can be stored for 5 days post thaw. [10] Prophylactic plasma transfusions might have an effect for people with a blood clotting disorder and receive an invasive procedure.
Cryopreservation for embryos is used for embryo storage, e.g., when IVF has resulted in more embryos than is currently needed. One pregnancy and resulting healthy birth has been reported from an embryo stored for 27 years, after the successful pregnancy of an embryo from the same batch three years earlier. [39]
In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI).

With a controlled, standardised freezing and thawing process, the red blood cells can be stored in frozen condition for up to 30 years. [ 38 ] [ 47 ] Also for cryopreservation, cell processors are frequently used for both the pre-freezing glycerolisation procedure and for washing away the glycerol after thawing of the red blood cells.
