Sample haemolysis most often occurs with in-vitro damage. This can be minimised by:
- Using appropriately sized needles and avoiding excessive negative pressure during collection.
- Using gentle inversions when mixing blood tubes after collection (which includes red top CAT tubes and gold top SST tubes).
- Allow the serum sample to clot at room temperature (i.e. 30-60 minutes) in a stable environment - only refrigerate the serum tube after a strong clot has formed; production animals and horses need at least 60 minutes for the clot to form
- After the clot has formed, the sample can be centrifuged and serum removed from the clot - the separated serum can then be transported in a plain, labelled tube.
- Avoid prolonged storage, or exposure to excessive heat or cold.
- Fasting the patient prior to sampling (if appropriate) helps avoid sample lipemia (this is a common cause of haemolysis in companion animals).
