Paternity Testing

Paternity testing can be done by older methods including ABO blood group typing, analysis of various other proteins and enzymes, or using human leukocyte antigen (HLA). However, DNA testing became the only formal and exact method for the paternity testing now. For DNA testing of paternity determination, the DNA collection using an easily obtained cheek swab saliva sample. Fast, proprietary and confidential genetic profiling of the child and alleged father with 99.999% probability/accuracy of results. In the common DNA paternity case, the alleged father and child are tested using polymerase chain reaction (PCR), Short tandem repeat (STR) and restriction fragment length polymorphism (RFLP) methodologies. Results for a DNA paternity case are available in an average of 3-4 days from receipt by the most paternity testing laboratory. Cheek swab saliva testing can be done immediately after birth, and typically the child and alleged father are tested. Results exclude or confirm the biological father with an accuracy rate exceeding 99.9%. [The Journal of American Science. 2006;2(4):76-92].
