Ultrasonla anne karn\u0131ndan yap\u0131lan \u00f6l\u00e7\u00fcmlerle amniyon s\u0131v\u0131 indeksi yani amniyon s\u0131v\u0131s\u0131n\u0131n miktar\u0131 belirlenir. Anne karn\u0131ndan uterusun 4 k\u00f6\u015fesindeki amniyon s\u0131v\u0131s\u0131 miktar\u0131 \u00f6l\u00e7\u00fcl\u00fcr ve toplam\u0131 al\u0131n\u0131r. Toplam AS\u0130 miktar\u0131 5 cm ve alt\u0131nda ise anormal, 5-8 cm aras\u0131nda ise azalm\u0131\u015f kabul edilir. 250\u2032den fazla olmas\u0131 ise fazla (polihidramnios) olarak de\u011ferlendirilir.

Ortalama hacim gebeli\u011fin 16. haftas\u0131nda 200 ml iken 3.trimesterde 1000 ml \u2018ye ula\u015f\u0131r ve 38.haftadan sonra haftada ortalama 150 ml olmak \u00fczere giderek azal\u0131r.
