Chemiluminescence Immunoassay for Prostate-Specific Antigen

More Information
  • Received Date: May 09, 2007
  • Revised Date: August 12, 2007
  • The chemiluminescence immunoassay (CLIA) for serum total prostate-specific antigen (T-PSA) was developed. The reaction of luminol with hydrogen peroxide was introduced into this chemiluminescence system. The detection limit is established as 0.12 μg/L (n=10, mean of zero standard + 2SD) and the analytical recovery of PSA is 83.8%-118.7%. The intra-assay and inter-assay CVs vary from 4.4%-5.0% and 6.2%-11.7%, respectively. The experimental correlation coefficient of dilution is found to be 0.999. Compared with immunoradiometric assay (IRMA) kits, the correlative equation is y=1.07x+0.68, and correlation coefficient r= 0.97. The standard range for the method is 1.5-80 μg/L, and it presents good linearity.
