Serum Sample Storage - Free



Don’t worry! Our serum storage facility is available free of charge and your samples will be safely stored until you are ready to test, allowing you time to complete the case work-up, and:


  • Sample when the animal is most symptomatic
  • Time the sampling so it avoids any interference with medication
  • Complete initial rule-out tests and/or diet trials
  • Wait for insurance approval
  • Allow the pet owner time to make a decision on allergy testing


Simply tick the box on your sample submission form to request the use of this free facility.


*Initial storage period is 3 months, after which you will be contacted to find out if you are ready to test.



  • A diagnosis of allergic disease has been made
  • The animal was symptomatic when the sample was taken (this is the optimum time to sample)
  • The animal is not on / has not recently been on any medication which could interfere with test results
  • The animal has not been on a restricted diet for at least 8 weeks (applicable to food test only)
  • The sample has been spun down to provide serum and to reduce the risk of haemolysis (if this is not possible double the volume of whole blood can be sent but this does increase the risk of repeat sampling being required)
  • All samples are clearly labelled and minimum sample requirements adhered to
