In 886 consecutive ultrasound examinations subjective assessment of the amniotic fluid volume was performed and graded into 3 categories: normal, decreased, and increased. Following that, a four-quadrant sum (amniotic fluid index) was performed by the same experienced ultrasonographer and divided into 3 categories using the 5th and 95th percentiles. The sensitivity of the subjective analysis to diagnose a decreased amniotic fluid volume when compared with the amniotic fluid index was 58% (95% confidence interval, CI: 40\u201370%), with a false-positive rate of 17% (CI 8\u201332%). The sensitivity of the subjective analysis to diagnose an increased amniotic fluid volume when compared with the amniotic fluid index was 100% (CI 70\u2013100%). However, the false-positive rate was 74% (CI 55\u201385%). Diagnosis of a normal amount of amniotic fluid by the subjective technique had a sensitivity of 96% (CI 95\u201397%) and a false-positive rate of 3% (CI 2\u20134%). Subjective ultrasonographic assessment of the amniotic fluid volume may serve as a screening test for the experienced ultrasonographer. However, when a decreased or increased amount of amniotic fluid volume is suspected, one may elect to use the amniotic fluid index for confirmation of the subjective impression.<\/jats:p>","DOI":"10.1159\/000263836","type":"journal-article","created":{"date-parts":[[2009,11,27]],"date-time":"2009-11-27T16:32:47Z","timestamp":1259339567000},"page":"256-260","source":"Crossref","is-referenced-by-count":7,"title":["Subjective Ultrasonographic Assessment of Amniotic Fluid Depth: Comparison with the Amniotic Fluid Index"],"prefix":"10.1159","author":[{"given":"Mordechai","family":"Hallak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Kirshon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"O\u2019Brian Smith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark I.","family":"Evans","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David B.","family":"Cotton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,11,26]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000263836","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T12:52:08Z","timestamp":1777553528000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000263836"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,26]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000263836","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,26]]}}}
