[Using fingerprints for health diagnosis: computerised scanning validation]

Area of Science:

• Dermatoglyphics
• Medical Diagnostics
• Biometrics

Background:

• Fingerprints contain genetic markers.
• Traditional methods for analyzing fingerprints can be time-consuming and subjective.
• Developing objective and efficient diagnostic tools is crucial in healthcare.

Purpose of the Study:

• To validate a computerized fingerprint scanning system (M1) as a health diagnosis instrument.
• To compare the efficiency and reliability of computerized scanning (M1) against traditional methods (M2).

Main Methods:

• A sample of 15 individuals was analyzed.
• Two methods were employed: computerized scanning (M1) and traditional analysis (M2) following Cummins and Midlo's protocol.
• Two investigators performed the analysis to assess inter-observer reliability.

Main Results:

• Computerized scanning (M1) demonstrated superior quantitative capacity for line identification and higher efficiency.
• M1 showed high reproducibility and reliability, with no significant differences in intra- or inter-investigator observations.
• Traditional methods (M2) exhibited significantly greater variability in inter-investigator differences.

Conclusions:

• The computerized fingerprint scanning prototype (M1) is validated as an efficient and reliable health diagnostic instrument.
• M1 effectively processes genetic marker images from fingerprints.
• This technology offers a promising advancement in objective health diagnostics.
