Test Overview
Flow Cytometry
Diminished (nonreactive) responses to recall antigens are consistent with a primary or secondary immunodeficiency disease that affects T lymphocytes (cellular immunity). Nonreactive responses are not specific for a particular disease and do not indicate the degree of immunodeficiency.
Viability of Lymphocytes at Day 0: >=75%; Max Prolif of CA as %CD45: >=5.7%; Max Prolif of CA as %CD3: >=3.0%; Max Prolif of TT as %CD45: >=5.2%; Max Prolif of TT as %CD3: >=3.3%.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
