8/28/2023 0 Comments Pistachio and cashew allergy![]() Cashew and pistachio nuts are from the same botanical family. Peptide microarray technology hasn’t been studied in Australia for diagnosing cashew nut or other clinical food allergy. It is minimally invasive and has diagnosed peanut allergy and severity almost as accurately as an OFC without the risk of a life-threatening reaction. Peptide microarray technology can be applied innovatively to diagnose food allergy. This underscores the urgent need to develop accurate diagnostic methods for cashew allergy. The scarcity of information on cashew allergy and limitations with diagnosis causes considerable anxiety for affected families and places a burden on health care resources. Skin prick testing is more accessible but has an unacceptably high false positive rate when the history is unclear or is used as a screening tool. It is a costly, time consuming and labour intensive test that needs to be conducted in specialised medical clinics, leading to limited access and long waiting lists across Australia. The “gold standard” for diagnosing cashew allergy, the oral food challenge (OFC), has the potential to cause a life-threatening allergic reaction. Despite this, much is still not known about it, compared to peanut allergy which has been reported extensively.Ĭurrently available tests used to diagnose cashew allergy have significant limitations and have not changed in over three decades. Cashew nut allergy is typically life-long. Cashew allergy causes more severe reactions than peanut including life threatening severe allergic reactions termed anaphylaxis, potentially resulting in death.
