Blood tests are the most accurate. Several dozen allergy tests are currently carried out in Taiwan, but most hospitals don't take the initiative to test patients. Studies have shown that dust mites are the most common allergen in Taiwan (affecting 90 % of allergy sufferers), followed by mold and cockroaches.
現階段台灣所測試的過敏原不過數十種，而且除非必要，一般醫院很少主動為過敏病患測試過敏原，因為根據研究，台灣最普遍的過敏原是塵 (（高達九成），其次是黴菌、蟑螂等。
