ResumoThe value of the signs and symptoms of pregnancy and of the pregnancy diagnostic test as predictors of pregnancy was estimated for 1,592 women seen in general practice. The presence of a sign or symptom alone is a poor pointer to a diagnosis of pregnancy. The combination of pairs of features improves the value, the best being breast signs combined with either the presence of signs of pregnancy on vaginal examination or a palpable fundus, both giving predictive values of 0·89. The pregnancy diagnostic test alone, however, had a predictive value of 0·91, a value of 1·00 indicating 100 per cent reliability.
