KL-6 is a sialylated carbohydrate antigen that was detected by Kohno et al. in 1985. It is a high molecular weight glycoprotein that is expressed by type II alveolar epithelial cells and is a mucin which belongs to MUC-1 in cluster 9.1,2 ,4 It has been confirmed that the serum KL-6 level is significantly higher in
subjects with interstitial pneumonia than in healthy volunteers or subjects with other respiratory diseases, and it has been shown by ROC analysis that serum KL-6 is a diagnostically useful indicator.3 In addition, because serum KL-6 Levels are significantly higher in subjects with active interstitial pneumonia than in subjects with inactive pneumonia, serum KL-6 is considered to be useful for assessing disease activity.
Furthermore, it has been noted that this parameter changes according to the pathology of interstitial pneumonia during
