Mannose-binding Lectin (MBL)
Use
The determination of MBL concentrations in serum may be useful for the elucidation of suspected immune defects and as a prognostic indicator alerting to the need for heightened therapeutic or prophylactic measures in immunosuppressed patients, including patients receiving cancer chemotherapy and patients with cystic fibrosis, SLE, or rheumatoid arthritis.
Special Instructions
Not provided.
Limitations
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. Diminished MBL levels can occur due to allelic variants in the promoter and/or structural regions of the MBL gene. Only normally oligomerized forms of MBL can efficiently bind to microbial carbohydrates and associate with MASPs.
