There are two basic types of DNA testing that can be done before delivery. These include amniocentesis and CVS, or Chorionic Villus Sampling. An amniocentesis is generally performed during the second trimester of pregnancy. Typically, it would take place between the 14th and the 20th week of pregnancy.
Including the biological mother in the testing is optional. We can do the testing without her sample included, and we do provided conclusive results on a regular basis when only testing the alleged father and the child. Results will be 100% accurate based on the samples and information sent to us to test with.
