首先你要知道allergy test係咩一回事
先講IgG test,因為佢係廢嘅,IgG本身只係memory antibody,正常嘅immune system都會識整IgG antibodies,你搵呀豬呀狗去驗都會有positive,有positive反而仲反映到你對呢樣substance有耐受性
同埋好多allergy test根本冇standardized normal values,只要驗到有你就會驚,覺得自己對呢樣substance敏感,但係其實可能個數值處於正常範圍之內而你唔知,片入面個醫生驗到有7x種food allergies但係佢根本就冇事冇幹

而且broad based嘅IgE test又好多false postives/ negatives
準確嘅test係要玩大包圍,唔可以單靠一個test去搵出你係咪對某樣嘢敏感
最重要嘅始終都係history,而呢樣嘢你會比你嘅醫生更清楚
你仲可以簡單做個Skin prick test,甚至係RAST或者ImmunoCAP test,因為佢哋係Allergen-specific嘅IgE test,要注意嘅係數值越高代表你越高可能對呢樣substance敏感,完全反映唔到你對呢樣substance嘅allergy有幾嚴重
