Special Instructions
Not provided.
Limitations
Certain drugs, including lithium, cyclosporine, cisplatin, carboplatin, and aminoglycoside antibiotics, can increase β2-microglobulin concentrations. The assay method ICMA (Immunochemiluminometric assay) used for this test makes the results potentially incompatible with results obtained using other assay methods.
