title: Correlation of an enzyme immunoassay with the radioimmunoassay for CA-125.
abstract: Serum CA-125 concentrations from 60 women were determined by radioimmunoassay and an enzyme immunoassay. Correlation of the CA-125 values obtained by the two methods indicated a linear relationship between 13 and 73 U/ml, lower values in the enzyme immunoassay, and a lower sensitivity of the enzyme immunoassay as compared with the radioimmunoassay.
