DNA testing utilized particular regions in our DNA that are unique to every individual. These regoins are tested using tehcnques such as RFLPs (Random Fragments Length polymorphisms), SNP (Single Nucleotide Polymorphism), STR (Short Tandem Repeats), Y chromosome (for males) and mitochondria DNA analysis (for females).
Answer:
DNA testing utilized particular regions in our DNA that is unique to every individual. And these regions can be tested using different techniques.

DNA testing:
DNA testing also called genetic testing allows the determination of blood lines and genetic diagnosis of susceptibilities to inherited diseases.
Function of DNA testing:
In humans, genetic testing can be used to regulate a child's parentage (genetic mother and father) or in general a person's lineage. In addition to studying true chromosomes to the level of individual genes, DNA testing in a broader sense comprises certain biochemical tests for the possible incidence of genetic diseases, or mutant forms of genes related with increased risk of developing genetic disorders.
Techniques of DNA testing:
• PCR (Polymerase chain reaction)
• RFLP (Restriction fragment length polymorphism)
• SNP (Single nucleotide polymorphism)
• STP (short tandem repeats)
• Mitochondria DNA analysis for females
