新的研究警告HbA1c测试可能误诊断南亚的糖尿病, A new study warns HbA1c tests may misdiagnose diabetes in South Asia due to widespread blood disorders, delaying treatment.

2026年2月9日刊登在《柳叶刀区域健康:东南亚》上的新研究报告警告说,HbA1c测试可能给包括印度在内的南亚数百万人带来不准确的结果,因为贫血、血红蛋白病和G6PD缺乏症的发病率很高,从而可能错误地降低或提高读数。 A new study published in The Lancet Regional Health: Southeast Asia on February 9, 2026, warns that the HbA1c test may give inaccurate results for millions in South Asia, including India, due to high rates of anaemia, haemoglobinopathies, and G6PD deficiency, which can falsely lower or raise readings. 这些状况在印度尤其普遍,可能会将糖尿病诊断推迟四年,特别是在未发现G6PD缺乏症的男子中,并可能损害公共健康数据。 These conditions, especially prevalent in India, may delay diabetes diagnosis by up to four years, particularly in men with undetected G6PD deficiency, and compromise public health data. 研究人员敦促以口服葡萄糖耐受测试、自我监测、氟氯胺酮或连续的葡萄糖监测取代或补充HbA1c,特别是在资源贫乏的地区,并建议例行的血解筛查,以提高诊断准确性和护理结果。 Researchers urge replacing or supplementing HbA1c with oral glucose tolerance tests, self-monitoring, fructosamine, or continuous glucose monitoring, especially in low-resource areas, and recommend routine hematologic screening to improve diagnosis accuracy and care outcomes.
