Prenatal Test

What is it?

DNA testing can be conducted while a woman is pregnant by using either a chorionic villus sampling (CVS) or amniotic fluid sample. These sample types are collected during pregnancy by a qualified medical practicioner. Please consult your personal physician for medical guidance.

Here are some commonly asked questions below but please contact us at DNAinquiry@labcorp.com to discuss DNA testing options during pregnancy.

What is a CVS?

A Chorionic Villus Sampling is a procedure where a sample of the placenta of the fetus is taken during early pregnancy by a qualified medical practitioner.

What is amniocentesis?

This is a procedure to collect an amniotic fluid sample in early pregnancy by a qualified medical practitioner.

Who will collect a CVS or amniotic fluid sample?

These sample types are collected by a physician.  If a decision is made to perform prenatal testing, a collection kit with a chain-of-custody form and shipping instructions will be provided to your physician.

Does the mother have to provide a sample in a prenatal paternity test?

The mother’s sample is required in every prenatal test. The mother’s sample is tested to ensure that the fetal sample is pure and originates from the fetus, and not the mother.

Does a physician need to collect samples from the parents?

The doctor may collect buccal swab samples from the alleged father and the mother. However, if the physician prefers not to do this collection, LabCorp can arrange an appointment for the alleged father and the mother at one of our local collection sites.

Is a doctor’s order required for a prenatal test?

A doctor’s order is not generally required. However, in compliance with New York state law, LabCorp requires a prescription, court order, or ordering by other authorized persons for all DNA identity and/or relationship tests performed on a New York resident.

Do I need an attorney or court order for a prenatal test?

If all parties involved in the testing agree to participate voluntarily, neither an attorney nor court order is required. However, in compliance with New York state law, LabCorp requires a letter on the attorney’s letterhead authorizing relationship testing, a court order, prescription, or ordering by other authorized persons for all DNA identity and/or relationship tests performed on a New York resident.
