Test Overview
Flow Cytometric Immunophenotyping
As an aid in the diagnosis of LAD-1 syndrome, primarily in patients <18 years of age.
Normal (reported as normal or absent expression for each marker)
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Patients with normal beta2-integrin expression without functional activity have been described.(5-6) Therefore, expression of CD18 alone is insufficient to exclude the diagnosis of LAD-1; functional assays (eg, neutrophil chemotaxis, random migration assays) must be performed if the clinical suspicion is high.
