DNA Profile Test

DNA profile testing can be used for the identification of a person in an accident through the DNA testing of an individual person (one person), and provides strong identification functionality, such as for locating missing children

  • - Principle of testingDNA is a genetic substance that contains all personal genetic information, and each person has his or her own DNA pattern inherited from their parents, which distinguishes him or her from others. The DNA profile is the genetic information specific to a person that enables personal identification, and is the combination of gene loci featuring chain repetition.
    DNA profile testing is a test that uses DNA identification technologies that utilize the non-informative genetic area of an individual person.
    DNA profile testing can be used for the identification of an individual person in an accident, and in the case of children, it is possible to locate a missing child through a genetic information database if the DNA profile of the missing child is known. DowGene DNA Testing Company performs testing based on CODIS, used by the FBI in the U.S.
  • - Testable specimens Blood, hair with roots, oral epithelial cells, saliva, blood, toothbrushes, nails, body fluid-stained clothing, chewing gum, cigarette butts, etc.
  • - Test Procedures Request for testing → Test collection kit shipping → Collection of specimen and acceptance of application → DNA extraction → PCR amplification → Genotype analysis and interpretation → Notification of results
  • - Results analyzed by automatic base analyzer The peaks in the figure refer to unique genetic types that can be identified, and the combination of the genetic types is called a DNA profile.

  • The combination of numbers from a DNA profile can be individually identified like a social security number, and as it uses a non-genetic information area, it is independent of specific genetic diseases.
  • - Application cases of DNA Profile Testing
    • • When a pre-test is required for an accident
    • • When a pre-test is required to prevent missing children, or mixture
