BACKGROUND: The usefulness of coagulation tests performed before @entity1337 for surgery or to alleviate @entity158 is controversial. The aims of this study were: (1) to evaluate the prevalence of abnormal tests in a large cohort of healthy pregnant @entity1 and their association with @entity4282 ; (2) to assess the approach of the anesthesiologists to @entity1 with abnormal tests; (3) to evaluate the cost of performing coagulation tests before @entity1337 in all healthy pregnant @entity1 . METHODS: Data regarding @entity1337 , @entity4282 , PT, APTT, @entity2002 and platelet count were extracted from medical charts. RESULTS: There was no case of @entity4282 in 2546 pregnant @entity1 undergoing @entity1337 . PT and APTT results were obtained in 2871 @entity1 ; @entity2002 in 4063 @entity1 ; platelet count in 5090 @entity1 . Three of them (0.1%) had a prolonged PT, 4 (0.14%) had a prolonged APTT, 27 (0.53%) had platelets  <= 100   10(9)/L and 37 (0.91%) had plasma @entity2002 levels <3 g/L. No further tests were requested by the anesthesiologists in these @entity1 . Only @entity1 with platelets <80   10(9)/L were denied @entity1337 . Based on the data from the literature on the frequencies of @entity4282 after @entity1337 , a total cost ranging from 4.5 to 40 million @entity7634 to perform coagulation tests would be necessary to avoid one case of @entity4282 . DISCUSSION: Unselected coagulation tests before @entity1337 are not recommended, because @entity4282 is extremely rare in healthy pregnant @entity1 and the cost of screening is not justified.
