ABSTRACT:
This invention describes a process for the diagnosis of meconium stained amniotic fluid. Meconium staining is often the result of ongoing or transient fetal distress or prolonged gestation. This process involves the non-invasive illumination of the amnion with light of a specific wavelength and detecting the fluorescence of certain biological pigments contained within the meconium. The process uses a source of light and a means of selecting the desired wavelength of light, directing the light to the target area, retrieving the fluorescence, converting the fluorescent emission to an electrical signal, amplifying the signal and analyzing the signal with a data processing unit.
