Heavy black tea consumption and elevated CA 19-9 and CA 125 levels. A case report on a patient with ovarian endometriotic cysts

Abstract

In this case report, we present a case of false positive CA 19-9 and CA 125 levels in a patient with suspected endometriotic cysts. The patient is a 34-year-old nulliparous woman with heavy black tea consumption and elevated CA 19-9 and CA 125 levels. After discontinuation of black tea intake and careful exploration of other possible factors, CA 19-9 and CA 125 levels dropped markedly. As a conclusion, heavy black tea consumption can lead to false positive results of elevated CA 19-9 and CA 125 levels.

摘要

在此病例报告中, 我们报道了一例可疑子宫内膜异位囊肿的患者CA 19 -9和CA 125呈现假阳性。患者为一名34岁未产妇女, 大量饮用红茶使CA 19-9和125水平升高。停止饮用红茶后并仔细探索其他可能因素, CA 19 -9和CA 125水平明显下降。因此, 大量饮用红茶会可能会导致CA 19-9和CA 125水平升高的假阳性结果。
