Table 1

Blood test findings in the three cases.

Case	1	2	3
WBC ( /μL)	70800	36900	83500
Hb (g/dL)	8.4	11.5	10.6
Neutrophils (%)	86	95	92
Lymphocytes (%)	3	2	7
Eosinophils (%)	4
Monocytes (%)	2	2	1
Myelocytes (%)	3
NLR	28.7	47.5	13.1
PLT(104/μL)	31.6	17.8	29.4
CRP(mg/dL)	19.38	10.24	11.16
G-CSF(pg/mL)	748	22.4	617
IL-6 (pg/mL)	114	22.8	46.4

NLR, neutrophil/lymphocyte ratio; CRP, C-reactive protein; G-CSF, granulocyte-colony stimulating factor; IL-6, interleukin-6.The normal value of G-CSF is 5.78–27.5 pg/mL, and the normal value of IL-6 is 8 pg/mL or less.
