Lab Testing Services

What types of DNA testing does your medical lab provide?

Our medical lab provides a wide range of DNA testing services. We offer paternity tests that are used to determine the biological father of a child, as well as prenatal testing for genetic disorders and chromosomal abnormalities.

We also provide forensic DNA analysis in order to identify individuals from evidence collected at crime scenes, and we have the capability to detect mutations associated with certain inherited diseases or conditions.

Additionally, our lab specializes in providing ancestry-related genetic tests that can help people trace their family history and uncover unknown relatives.

Prenatal paternity testing

Prenatal paternity testing is a DNA test performed during pregnancy to determine the biological father of an unborn child. Prenatal paternity testing can be done as early as 9 weeks into the pregnancy. The test works by analyzing the DNA of the mother, father, and unborn child.
