STR Profiling

About this service

STR Profiling is described as analysis of short tandem repeat markers to generate a DNA profile. A profile can be compared with an appropriate reference profile, but this listing does not establish whether it includes profile generation only, a comparison or any database search. Mixtures, low-template or degraded DNA and interpretation can affect results. A profile is not proof of guilt, identity or relationship and does not guarantee court acceptance.

Service highlights

• Intended to generate or compare a profile from selected STR markers.
• The service's comparison and reporting scope must be confirmed.
• Not a clinical test or a determination of guilt or legal identity.

Who may consider it

• People with a defined DNA profiling or comparison question.
• Investigators or legal representatives who have confirmed the required forensic laboratory and evidence-handling process.

What to expect

Confirm current availability and quote, whether the service profiles or compares samples, the assay and report, accepted sample process, and any required chain-of-custody and accreditation.

Scope and limitations

STR profiling produces genetic marker data; interpretation depends on sample quality, mixtures, reference data and method. It does not by itself identify an individual, establish paternity, search a database, diagnose disease or prove guilt.
