Intestinal alkaline phosphatase (ALP) is more prevalent in individuals of blood group O or B, and increases after a meal, especially on a high-fat diet. We did not realize that clinicians could underestimate the importance of fasting for ALP measurement until one healthy adult showed a huge difference in ALP levels before and after a meal. We report a case of transient hyperphosphatasemia resulting in unnecessary workup due to intestinal ALP in a healthy adult of blood group O.
肠道碱性磷酸酶（ALP）在O型或B型血的个体中更为普遍，并且在进食后会升高，尤其是在高脂饮食后。直到一名健康成年人在进食前后的ALP水平出现巨大差异，我们才意识到临床医生可能低估了空腹对ALP测量的重要性。我们报告了一例因肠道ALP导致的短暂性高磷酸酶血症病例，该病例发生在一名健康的O型血成年人身上，导致了不必要的检查。
