Test Overview
Direct Immunofluorescence using flow cytometric techniques.
Evaluation of primary immunodeficiencies. A full lymphoid cell panel is run, including B and T cell quantitation and natural killer cell quantitation. Markers include CD3, CD4, CD8, CD16/56, CD19, and CD4:CD8 ratio (T4:T8 ratio).

*Pediatric Reference Ranges from Journal of Allergy and Clinical Immunology, vol. 112, No. 5, 11/2003 and studies performed at Michigan Medicine Flow Cytometry Laboratory. Absolute ranges are calculated utilizing absolute lymphocyte count ranges for the same age groups provided by the hematology laboratory.
