I used to make a suspension of fresh red cells in saline and freeze it in those little bullet-shaped tubes. Once thawed, the hemolysate held a stable hemolysis index for almost a week when refrigerated,
no preservative. Frozen at -70C, the aliquots held a stable value for two years.

Subject: IQC for haemolysis index
Hi all,
I think this may have been visited before, but we have Abbott analysers and would like to have some handle on how the haemolysis index is performing. Abbott don’t offer any IQC material for this.
What do other users (Abbott or otherwise) do?
Thanks in anticipation
Iain
