The invention provides an active tuberculosis diagnostic marker, a kit and application thereof. The diagnostic marker is characterized by comprising a blood biomarker MCEMP1 protein in a blood sample,the amino acid sequence of the MCEMP1 protein is as shown in the SEQ ID NO:1. The invention further provides the kit capable of rapidly detecting whether a subject suffers from active tuberculosis ornot. The kit comprises a total RNA extraction related reagent in a whole blood sample, a quantitative PCR related reagent and an ELISA related reagent. According to the active tuberculosis diagnosticmarker, the MCEMP1 is adopted as a biomarker for active tuberculosis detection for the first time, is used for clinical diagnosis and differential diagnosis of tuberculosis, and provides a new direction for clinical diagnosis of tuberculosis. 本发明提供了活动性结核病诊断标志物、试剂盒及其应用，其特征在于，包括血液样本中的血液生物标志物MCEMP1蛋白质，所述MCEMP1蛋白质的氨基酸序列如SEQ ID NO:1所示，还提供了能够快速检测受试者中是否患有活动性肺结核的试剂盒，所述试剂盒包括全血样品中总RNA提取相关试剂、定量PCR相关试剂、ELISA相关试剂。本发明首次采用MCEMP1作为活动性肺结核检
