[Detection of hCG serum levels in choriocarcinoma using monoclonal antibodies].
hCG values and those of its alpha- and beta-subunits are assessed in the serum of all patients treated in the Centre of trophoblastic disease. Commercial RIA kits with conventional antibodies are used. There was an opportunity to work with kits of Serono Co. with monoclonal antibodies, the so-called hCG MAIA clone kit which assesses hCG and its beta-subunit. In this IRMA-MAIA system 240 sera of patients with choriocarcinoma were processed. Comparison of hCG values found in the IRMA-MAIA test with values assessed with kits from Kosice revealed the following: 33% of the values in MAIA were higher, 57% were in agreement. 10% of the specimens were MAIA negative, while the Kosice values were low (50-100 i.u./l) and a negative finding was assumed. The authors investigated low (or false positive) hCG values and values obtained during the so-called residual reaction. According to the obtained results in this system of three highly sensitive monoclonal antibodies no cross reaction with LH occurs.
