Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
The Leukocyte Adhesion Deficiency Panel measures the receptors CD11a, CD11b, CD15s, and CD18 normally found on neutrophils. The percentage of patient neutrophils bearing these receptors is reported. Decreased values outside of the reference interval may correlate with abnormal neutrophil function. For example, CD11 and CD18 are decreased or absent in leukocyte adhesion deficiency (LAD) type I and CD15s is decreased or absent in LAD type II.
