Analysis Service

The Forensic DNA Division started DNA identification services in 1991 for the first time in South Korea and has been performing personal identification and confirmation of identity for various incidents and accidents. It obtained accreditation from KOLAS International Accreditation Agency in 2004 for the first time in South Korea and is recently teaching DNA identification techniques through the KOICA ODA project, etc. It has been internationally recognized for solving the Seorae Village Infanticide Case in 2006 and played a leading role in identification of victims of major disasters such as the Daegu Subway Fire, Sinking of the Sewol Ferry, etc.
Additionally, in accordance with the Act on the Protection and Support of Missing Children, etc. in 2005 and the Act on the Use and Protection of DNA Identification Information in 2010, the Forensic DNA Division has built a national DNA identification information database, and DNA quality control service for unresolved murder cases has been newly established as the statute of limitations for murder cases has been removed due to the amendment of the Criminal Procedure Act in 2015.
Furthermore, it carries out species identification and object identification of animals, plants, microorganisms, foods, etc. through DNA analysis and supports investigative agencies through “emergency analysis” for major violent cases.

Various Application Fields of DNA Identification


Introduction of Laboratory

The Forensic DNA Division consists of a DNA Analysis Lab, Trace DNA Analysis Lab, Emergency Precise Analysis Lab, Arrested Suspect Analysis Lab, Search Target Analysis Lab, DNA Information Management Lab, DNA Quality Control Lab, Missing Child Analysis Lab, DNA Identification Lab, and Forensic Biology Lab. Moreover, a Smart Lab of this institute is in operation on Jeju.

01 DNA Analysis Lab

The DNA Analysis Lab analyzes the DNA profile of human samples such as bloodstains, semen, saliva, hair and skin cells collected from crime scene evidence related to violent cases (murder, mutilation, robbery, sexual violence, etc.), narcotics offenders, traffic accidents, accidents, fraud, etc.

Role of DNA identification (between the investigative agency and court)

Precautions for collecting, packaging, storing, and transporting DNA evidence from crime scenes

02 Trace DNA Analysis Lab

DNA profiling is carried out in trace amounts of evidence collected at the crime scene. In particular, the evidence collected at a theft site often contains trace amounts of contact evidence that is less visible than normal bloodstains or semen. After obtaining the DNA type from such a small amount of contact evidence, the laboratory detects the DNA type of the criminal and helps the police solve the case.

DNA Profiling Work Flow

03 Emergency Precise Analysis Lab

The Emergency Precise Analysis Lab conducts DNA profiling and research on evidence related to urgent violent cases, accidents and criminal investigations as well as precise analysis on evidence in unsolved cold cases. Additionally, it provides urgent analysis services on the evidence of violent cases (murder, rape, robbery, traffic accidents, etc.) for local institutes. The laboratory makes great contribution in criminal investigations and solving incidents and accidents with faster and accurate DNA analysis and profiling in close cooperation with the police.

Emergency Analysis Handling Process

  • Pre-distribution of
    Analysis Request Sticker
  • Upon occurrence of
    an incident requiring
    emergency analysis,
    make a verbal report to the
    National Police Agency first
  • Filling in the sticker
    after receiving a request no.
  • Request for
    Emergency Analysis
  • Organizing the analysis team
    Notification of the result within
    the shortest time
04 Arrested Suspect Analysis Lab

The Arrested Suspect Analysis Lab compares the DNA database for unsolved cases through DNA analysis on the samples of suspects arrested for 11 major crimes (murder, rape, juvenile sexual assault, robbery, arson, abduction, habitual violence, organized violence, narcotics, special theft, murder of a ranked soldier under military criminal law, etc.) in accordance with the 『Act on Use and Protection of DNA Identification Information』 enacted on July 26, 2010. The DNA database for unsolved cases is built with DNA data isolated from the evidence of numerous rape, theft, and murder scenes.
For personal information protection, the requesting agency encodes the personal information and assigns an identification code to the arrested suspect sample. The DNA analysis result for the arrested suspect is stored in the arrested suspect database with the identification code, and the remaining sample and DNA are immediately disposed.

05 Search Target Analysis Lab

The Search Target Analysis Lab performs DNA profiling and research of a search target requested by the police with regard to the crime scene DNA identification information.

Services provided by the Search Target Analysis Lab

  • Listing the DNA data requested by the main and branch institutes, search and distribution of search results
  • Search of DNA types of search targets of related cases before the request of the police agency
  • Distribution of a copy of analysis report for the search-related request
  • DNA storage and management
  • Management of unsolved critical serial cases
06 DNA Information Management Lab

The DNA Information Management Lab performs search and management of DNA identification information of crime site evidence and arrested suspects by establishing a DNA Identification Management System (DIMS) in accordance with the 『Act on Use and Protection of DNA Identification Information』.

Services provided by the DNA Information Management Lab

  • Database listing and management of DNA identification information of crime scene evidence analyzed by this institute and each local institute
  • Database listing and management of DNA identification information of arrested suspects analyzed at the arrested suspect analysis lab of this institute
  • Investigation support for rapid case resolution, such as rapid criminal identification and detection of serial crimes committed by the same person through database search
  • Purpose of 『Act on Use and Protection of DNA Identification Information』 Article 1 of the Act stipulates that "This Act aims to contribute to criminal investigations and prevention and protect the rights and interests of citizens by establishing the requirements for the collection, use and protection of DNA identification information.
  • Necessity of DNA Identification Information Database Due to the increased number of violent cases and intellectualization of crime techniques, the laboratory obtains and manages “DNA identification Information’’ of persons who previously committed a violent crime and specifies a criminal for rapid arrestment by comparing DNA identification information detected in the stored data with the information detected at crime scenes.
07 DNA Quality Control Lab

The DNA Quality Control Lab performs quality control and research on DNA as well as manage remaining amounts of DNA used for current or past testing. Additionally, it operates the DNA identification database that rules out and performs DNA information analysis and research for the purpose of criminal investigation.
