Rapid DNA Typing

Rapid DNA typing generates STR genetic profiles from biological samples within 60 to 90 minutes at the point of collection, compressing the multi-day laboratory workflow of traditional forensic DNA analysis into a single automated instrument run that requires no specialist scientific training to operate. Border management officers, law enforcement investigators, military identification teams, and humanitarian identification programs across Pakistan use rapid DNA typing to confirm or exclude identity comparisons immediately at the sample collection location rather than waiting for centralized laboratory results.

The typing process runs inside a single-use disposable cartridge loaded with pre-dispensed reagents specific to the STR amplification chemistry. The operator collects a biological sample on a buccal swab or blood swab, inserts the swab into the cartridge inlet, and places the sealed cartridge into the rapid DNA instrument. From that point, automated microfluidic processes perform cell disruption, DNA release, magnetic bead purification, PCR amplification of the target STR loci, capillary electrophoresis fragment size separation, and laser-induced fluorescence detection of the separated allele peaks. Results display as an electronic STR allele table within the instrument run time. Additionally, the generated profile covers the 20 CODIS core loci and Amelogenin sex marker, meeting the minimum locus requirements for FBI NDIS database submission and international DNA database exchange.

Profile completion rates run above 95% on fresh buccal and blood swab samples collected under standard protocol conditions. Degraded or low-template samples produce partial profiles with reduced locus coverage. Furthermore, the instrument compares the generated profile directly against a reference profile loaded into the instrument database, returning a match or exclusion result alongside the profile data for immediate operational decision support at the collection point without requiring network connectivity to a remote database.

Data security on rapid DNA typing instruments uses encrypted profile storage and role-based access control, restricting profile viewing and export functions to authorized operator credentials. Moreover, audit trail logging records every sample loading, profile generation, comparison result, and data export event with timestamp and operator ID for chain-of-custody documentation supporting law enforcement and court admissibility requirements.

Tactical Supply Pakistan supplies rapid DNA typing systems to border control agencies, law enforcement forensic units, military identification formations, and missing persons identification programs requiring automated point-of-collection genetic profile generation across identity verification applications throughout Pakistan.
