Abstract:
Three home pregnancy tests, Clearblue (Tjellesen), Clearblue one step (Tjellesen) and Predictor (Organon), were tested and compared with respect to sensitivity, specificity, prozone-phenomenon and convenience for use. In addition, they were compared with two well-known pregnancy tests, HCG-Novoclone (Novo) and HCG-Nostick (Organon), which are used in several hospitals and drugstores. All three home pregnancy tests were found to be in agreement with the instructions for use with regard to sensitivity and prozone phenomenon. One test, Clearblue one step, showed false positive results when LH was added. Clearblue was found to be laborious and unhygienic in performance. Predictor seems to be the test of choice.
