T-cell counts in surviving patients. (A) CD3 counts, (B) CD4 counts, and (C) CD8 counts. The Y-axis maximum in each graft does not show the peak from early oligoclonal proliferations. The early oligoclonal peaks for patients DIG001, DIG009, and DIG010 are indicated on the grafts. Only 4 years of data are depicted because only one patient, DIG001, is more than 4 years from transplantation. The most recent CD3, CD4, and CD8 counts for patient DIG001 are 337/mm³, 178/mm³, and 112/mm³ from 8 years after transplantation, respectively. The normal CD3 T-cell count for age 2 days to 11 months is 1700 to 3600/mm³, for age 1 to 6 years is 1800 to 3000/mm³, for age 7 to 17 years is 1400 to 2000/mm³.³⁵  The normal CD4 T-cell count for age 2 days to 11 months is 1700 to 2800/mm³, for age 1 to 6 years is 1000 to 1800/mm³, for age 7 to 17 years is 700 to 1100/mm³.³⁵  The normal CD8 T-cell count for age 2 days to 11 months is 800 to 1200/mm³, for age 1 to 6 years is 800 to 1500/mm³, for age 7 to 17 years is 600 to 900/mm³.³⁵  These ranges all reflect the 25th to 75th percentiles.³⁵
