Specific IgE Sample Information
Specimen collection, handling and preparation
Blood should be collected by venipuncture, allowed to clot, and the serum separated by centrifugation. Specimens may be kept at room temperature (RT) for shipping purposes only, otherwise stored at 2ºC to 8°C if assayed within one week after collection or at -20°C if assayed later.
Avoid repeated freezing and thawing.

Note! Due to rise and fall of circulating venom and drug specific IgE antibodies, blood samples for testing with venom and drug ImmunoCAP should be collected no sooner than 2 to 3 weeks and no later than 6 months after an insect sting or drug exposure.
