Abbott Laboratories, Inc: An update to the Reagents and Specimen Collection and Handling/Preparation for Analysis sections of the IFU was required due to different issues with the various products.

Agency Publication Date: July 19, 2019

Affected Products

Product: C3 is an in vitro diagnostic assay for the quantitative determination of C3 in human serum or plasma. Antibodies to C3 combine with C3 in the sample to form insoluble immune complexes. The immune complexes cause an increase in light scattering (turbidity). The resulting increase in sample turbidity, measured at 604 nm, is directly proportional to the concentration of C3 in the sample.

All IFU's

Product: Immunoglobulin A is an in vitro diagnostic assay for the quantitative determination of immunoglobulin A in human serum or plasma. Antigen in the sample bonds to the specific antibody in the reagent, forming an immune complex. The immune complex causes an increase in light scattering, measured by reading turbidity at 700 nm, which correlates with the concentration of immunoglobulin A in the sample.

All IFU's

Product: Immunoglobulin G is an in vitro diagnostic assay for the quantitative determination of immunoglobulin G in human serum or plasma. Antigen in the sample bonds to the specific antibody in the reagent, forming an immune complex. The immune complex causes an increase in light scattering, measured by reading turbidity at 700 nm, which correlates with the concentration of immunoglobulin G in the sample.

All IFU's

Product: Immunoglobulin M is an in vitro diagnostic assay for the quantitative determination of immunoglobulin M in human serum or plasma. Antigen in the sample bonds to the specific antibody in the reagent, forming an immune complex. The immune complex causes an increase in light scattering, measured by reading turbidity at 700 nm, which correlates with the concentration of immunoglobulin M in the sample.

Product: Apolipoprotein A1 is an in vitro diagnostic assay for the quantitative determination of apolipoprotein A1 in human serum or plasma. Antibodies to apolipoprotein A1 combine with apolipoprotein A1 in the sample to form insoluble immune complexes. The immune complexes cause an increase in light scattering (turbidity). The resulting increase in sample turbidity, measured at 804 nm, is directly proportional to the concentration of apolipoprotein A1 in the sample.

Product: C4 is an in vitro diagnostic assay for the quantitative determination of C4 in human serum or plasma. Antigen in the sample bonds to the specific antibody in the reagent, forming an immune complex. The immune complex causes an increase in light scattering, measured by reading turbidity at 604 nm, which correlates with the concentration of C4 in the sample.

Product: The,K -ASSAY HP assay is intended for the quantitative determination of human haptoglobin by immunoturbidimetric assay. The antiserum used in the kit was produced against purified human haptoglobin. The haptoglobin antibody interacts with the haptoglobin in the serum forming immune complexes . The immune complexes cause an increase in light scattering which correlates with the concentration of haptoglobin.

All IFU's

Product: Apolipoprotein B is an in vitro diagnostic assay for the quantitative determination of apolipoprotein B in human serum or plasma. Antibodies to apolipoprotein B combine with apolipoprotein B in the sample to form insoluble immune complexes. The immune complexes cause an increase in light scattering (turbidity). The resulting increase in sample turbidity, measured at 604 nm, is directly proportional to the concentration of apolipoprotein B in the sample.

All IFU's

Product: Transferrin is an in vitro diagnostic assay for the quantitative determination of transferrin in human serum or plasma. Antigen in the sample bonds to the specific antibody in the reagent, forming an immune complex. The immune complex causes an increase in light scattering, measured by reading turbidity at 700 nm, which correlates with the concentration of transferrin in the sample.
