Abstract:
We studied the performances of the 17b-estradiol determination with the Kryptor System (Cis Bio international), in assisted medical procreation cycles. The detection is based on Trace technology. We compared this method with Estradiol-6 method on ACS-180 (Bayer Diagnostics). The Kryptor method is sensitive, has a good precision and accuracy. Comparison with ACS-180 showed a good correlation but results were much higher. Patients under stimulation for assisted procreation were followed by the two methods. The results were close to those obtained with ACS-180 but significantly higher. Thus it was necessary to define the levels which have to be reached before ovulation induction.
