Paternity testing provides scientific evidence of whether a man can be a child’s biological father. Paternity is determined by comparing the child’s DNA with the DNA profile of the alleged father.

Twin DNA testing can be used to confirm if two individuals are identical or non-identical (fraternal) twins. Should a twin need an organ or tissue transplant, an identical twin would be an optimal donor in most instances.

A single-party DNA test is a way to keep a sample of DNA on file should it ever be needed.

Maternity testing provides scientific evidence of whether a woman can be a child’s biological mother. Maternity is determined by comparing the child’s DNA with the DNA profile of the alleged mother.

A grandparentage DNA test is used to establish a genetic family relationship between a possible grandparent and grandchild or to establish paternity if the child’s alleged father is not available for testing.
