Test Overview

Test Methodology

Flow Cytometry

Test Usage

Diminished responses to lectin mitogens are consistent with a primary or secondary immunodeficiency disease. Abnormal results are not specific for a particular disease, and the magnitude of the abnormality is not necessarily related to the degree of immunodeficiency.

Reference Range

Viability of Lymphocytes at Day 0: >=75%; Max Prolif of PHA as %CD45: >=49.9%; Max Prolif of PHA as %CD3: >=58.5%; Max Prolif of PWM as %CD45: >=4.5%; Max Prolif of PWM as %CD3: >=3.5%; Max Prolif of PWM as %CD19: >=3.9%.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
