Papillary traces

In 2006, IGNA was the very first French private laboratory to provide comprehensive expertise encompassing both papillary traces and genetic fingerprints in a coordinated manner.


The papillary trace revelation processes used by IGNA are developed in order to preserve the DNA and any other trace evidence.


By undertaking these two expert assessments collectively, it becomes possible to view contact markings on objects, seemingly not exploitable, and to target their sampling for DNA research purposes.

Furthermore, processing times are then reduced.

Further explanation

Fingerprint identification techniques have been used for forensic purposes since the end of the 19th century.

Every individual has unique fingerprints and palm prints. Even monozygotic twins, despite sharing the same DNA, have different prints. These prints remain unaltered during the course of life and are practically indestructible, even in the case of minor surface damage to the epidermis.
