Other correlations such as between MBL level and TgAb concentration or hemoglobin (Hgb) in controls or between MBL level and bilirubin concentration in patients with hypopituitarism or between MBL level and potassium concentration (negative correlation) in patients with other pituitary diseases can be neglected and therefore they will be not discussed in this paper. Here, MBL2 is linked to hypopituitarism.
