Device Description
PSA in serum exists in several forms including free, uncomplexed PSA and PSA complexed to several protease inhibitors including α-2-macroglobulin, α-1antichymotrypsin (ACT), and α-1-antitrypsin. It should be noted that there are no existing commercial methods that can recognize PSA bound to α-2-macroglobulin. However, it has been demonstrated that the proportion of PSA complexed with ACT increases as a function of the total PSA concentration, and that the majority of immunoreactive PSA in cancer patients is in complex with ACT. The Bayer cPSA Assay uses a monoclonal antibody for capture which recognizes both free and complexed PSA, but which, when bound to free PSA, precludes the binding of other antibodies specific for the free form of PSA. The inclusion of a second, unlabelled monoclonal antibody which is specific for free PSA prevents the binding of free PSA in the cPSA assay and allows measurement of only PSA which is complexed with ACT. cPSA can be used as a single test alternative to free and total PSA in management of patients with CaP.

1. Intended Use
The Bayer ADVIA® IMS cPSA assay is an in vitro diagnostic device intended to quantitatively measure complexed prostate specific antigen (cPSA) in human serum. This assay is indicated for the measurement of serum complexed PSA as an aid in management (monitoring) of prostate cancer patients. Complexed PSA values obtained using the Bayer ADVIA IMS assay method must be interpreted in conjunction with all other available clinical and laboratory data before a medical decision is determined.
Prostate Specific Antigen (PSA) is a secretory product of the epithelial cells of human prostatic tissue, whether normal, benign, or malignant. The tissue specificity of PSA makes it a sensitive and specific tumor marker as an aid in management (monitoring) prostate cancer patients and disease progression following surgery or other therapies. PSA in serum exists in several forms including free, uncomplexed PSA and PSA complexed to several protease inhibitors including a-2-macroglobulin, a-1antichymotrypsin (ACT), and a-1-antitrypsin. It should be noted that there are no existing commercial methods that can recognize PSA bound to α-2-macroglobulin. However, it has been demonstrated that the proportion of PSA complexed with ACT increases as a function of the total PSA concentration, and that the majority of immunoreactive PSA in cancer patients is in complex with ACT. The Bayer cPSA Assay uses a monoclonal antibody for capture which recognizes both free and complexed PSA, but which, when bound to free PSA, precludes the binding of other antibodies specific for the free form of PSA. The inclusion of a second, unlabelled monoclonal antibody which is specific for free PSA prevents the binding of free PSA in the cPSA assay and allows measurement of only PSA which is complexed with ACT. cPSA can be used as a single test alternative to free and total PSA in management of patients with CaP.
