FLUORESCENCE SPECTRUM AND DECAY MEASUREMENT FOR HSIL VS NORMAL CYTOLOGY DIFFERENTIATION IN LIQUID PAP SMEAR SUPERNATANT
- Conference date: 31 October–1 November 2008
- Location: Florence (Italy)
Cervical smear material contains endo and exocervical cells, mucus and inflammative, immune cells in cases of pathology. Just not destroyed keratinocytes lay on the glass for microscopy. Liquid cytology supernatant apart other diagnostics could be used for photodiagnostic. The spectroscopic parameters suitable for Normal and HSIL cytology groups supernatant differentiation are demonstrated.
The dried liquid PAP supernatant fractions—sediment and liquid were investigated. Excitation and emission matrices (EEM), supernatant fluorescence decay measured under 280 nm diode short pulse excitation and fluorescence spectroscopy by excitation with 355 nm laser light were analyzed.
The differences between Normal and HSIL groups were statistically proven in the certain spectral regions. Fluorescence decay peculiarities show spectral regions consisting of few fluorophores. Obtained results on fluorescence differences in Normal and HSIL groups’ supernatant shows the potency of photodiagnosis application in cervical screening.
