Primary Outcome Measures:
  • Determination of the sensitivity and specificity of the rapid PSA assay by comparing the results obtained from the test strip reading by three independent blinded observers with those from standard plasma PSA assay. [ Time Frame: day of test ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determination of the threshold which maximizes the performance of the semiquantitative test. Determination of interobserver agreement. [ Time Frame: at the last inclusion ] [ Designated as safety issue: No ]

    rapid prostate specific antigen assay.
Detailed Description:

Screening and surveillance of prostate cancer typically involves sensitive laboratory techniques for the quantification of plasma prostate specific antigen (PSA). In this study, we determine the sensitivity and specificity of a simple test strip based PSA assay using only a few drops of whole blood as compared to a standard plasma PSA assay. Blood samples will be taken from hundred patients who are followed for a prostatic disease needing PSA surveillance. Before decantation of the samples, a few drops of blood will serve for the rapid test on strips. Plasma PSA levels will be determined with the TRACE ("Time Resolved Amplified Cryptate Emission") technology in homogeneous liquid phase. The results from the rapid test can then be compared to the plasma levels obtained by TRACE.
