The pH of amniotic fluid is :

Ans. is b i.e. 7.1 to 7.3 Amongst the given options - 7.1 to 7.3 seems to be the most appropriate option. Also know : Specific gravity of Amniotic fluid : 1.008 to 1.010 Osmolality : 250 mosm/L Completely replaced in 3 hours. Rate of amniotic fluid turn over is 500cc/hr. Volume of Amniotic fluid : Weeks of Gestation Amniotic Fluid - 16 weeks - 200 ml - 28 - 30 weeksdeg - 1000 ml - 36 weeks - 1000 ml - 38 weeks - 900 ml - 40 weeksdeg - 800 ml - 42 - 43 weeksdeg - 200 ml Extra edge : Amniotic fluid inhibits bacterial growth; phosphate to zinc ratio is a predictor of inhibitory activity. In case of intraamniotic fluid infections - "Inorganic phosphorous levels in amniotic fluid are raised".
