  • Immunofixation, Daratumumab-Specific, Serum 123218

    3 analytes · Serum · Fasting not stated · Turnaround 6 - 8 days

    Method and collection
    Method
    Electrophoresis followed by immunodiffusion against mono-specific antisera to immunoglobulin and individual heavy and light chains (IFE); turbidimetric quantitation of IgA, IgG, IgM. The HYDRASHIFT 2/4 daratumumab gel shift assay uses an anti-daratumumab antibody to allow for the migration of Daratumumab/anti-daratumumab complexes away from the γ globulin zone on IFE, toward the α1-globulin fraction, thus removing IgG κ interference in the γ globulin zone caused by Daratumumab in the patient's serum.
    Preparation
    Overnight fasting is preferred, but not required.
    Collection
    Separate serum from red cells.

    Method
    Electrophoresis followed by immunodiffusion against mono-specific antisera to immunoglobulin and individual heavy and light chains (IFE); turbidimetric quantitation of IgA, IgG, IgM. The HYDRASHIFT 2/4 isatuximab gel shift assay uses an anti-isatuximab antibody to allow for the migration of isatuximab/anti-Isatuximab complexes away from the gamma globulin zone on IFE, toward the alpha-1-globulin fraction, thus removing IgG kappa interference in the gamma globulin zone caused by isatuximab in the patient's serum.
    Preparation
    Overnight fasting is preferred but not required.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
