The following data were collected for most of the subjects: blood routine (33 cases), ferritin (29 cases), Anti streptolysin O (ASO) (33 cases), Epstein-Barr virus (EB virus) (17 cases), hepatitis B (22 cases), erythropoietin (EPO) levels (16 cases), etc. FTL levels detected by ELISA were negatively correlated with RBC and Platelets (PLT) and positively correlated with ferritin, CRP, and HBeAg. Here, FTL is linked to Hepatitis.
