Pregnosticon-Planotest (PPT), produced by N.V. Organon, is an immunological latex-suspension pregnancy test that can be read in 2 minutes (or up to 60 minutes) and requires no special equipment such as centrifuges. Parallel pregnancy tests, using PPT and the biological Galli-Mainin Reaction (GMR) were carried out on 381 women for a total of 407 tests. The cases included 334 possible early pregnancies, 38 supected extrauterine pregnancies, and 35 suspected fetal deaths. The 2 tests agreed in 93.9% of the cases, and of 23 cases on which results differed, the PPT reading proved correct for 21 cases. Both tests gave false-negative readings for 36 early pregnancies and 1 extrauterine pregnancy. However, PPT results were correct for 80% of the extrauterine pregnancies (where production of human chorionic gonadotropin, the substance tested for, is low); the GMR was correct in 68.8% of these cases. The sensitivity of PPT was also shown in its early detection of pregnancies - 3.3-4 days earlier than with GMR. PPT is thus judged to be a sensitive, reliable, simple, and quick pregnancy test.
