When it comes to prenatal DNA testing, it’s important to understand the difference between invasive and non-invasive methods.

Invasive DNA Testing

Invasive testing involves collecting DNA directly from the womb using procedures like amniocentesis. These procedures are considered surgeries and carry serious risks, including infection and miscarriage. Because of the potential danger to both mother and baby, invasive testing is rarely needed and is not recommended for routine paternity testing.

Non-Invasive DNA Testing

Non-invasive prenatal paternity testing is completely safe. It requires only a simple blood draw from the mother and a DNA sample from the alleged father (usually a cheek swab). Small fragments of the baby’s DNA naturally circulate in the mother’s bloodstream, and certified labs can use these samples to determine paternity with high accuracy.

Key benefits:

• No risk of miscarriage or complications

• Safe for both mother and baby

• Can be performed starting at 6 weeks of pregnancy (recommended at 7–8 weeks)
