[Detection of urinary substances in stains from amniotic fluid, urine and the blood of pregnant women using thin-layer chromatography].
When examining traces of biological origin it is possible to draw conclusions from the findings of some urinary constituents in a stain produced by urine; via foetal urine, however, in the spots also amniotic fluid can be detected. By chromatographic analysis on a thin layer the authors are able to detect in spots from amniotic fluid urea without hippuric acid, in urine spots urea, creatinine and hippuric acid; in blood stains under equal conditions none of the above constituents is detected. The results, using the above method, can be considered a contribution which helps to differentiate these traces and it can be also used to detect amniotic fluid in stains.
