To determine normal pH in vaginal, ocular, or gastric fluid. Vaginal/Amniotic Fluid: pH determination is used as a screening system in detecting rupture of the amniotic membrane in pregnant women. Rupture of the amniotic membrane can result in leakage of small volumes of amniotic fluid into the upper vagina.

Dextran-coupled pH-sensitive single-excitation/dual-emission dye SNARF-1 was pressure-injected into individual cells or the interstitial space of 16- to 256-cell embryos, and pH was continuously recorded during subsequent development for time periods of up to 8 h. A novel calibration technique was developed,
