Ig, immunoglobulin; Hib, Haemophilus influenzae type b; WBC, white blood cell; Hgb, hemoglobin; MCV, mean cell volume; PLT, platelets; ANC, absolute neutrophil count; Abs, absolute; Lymph, lymphocytes. Age-appropriate ranges were identified for immunoglobulins (9), CBC (10), lymphocyte subsets (11) and CD4:CD8 ratio (12).
