This part explains the practical side of Non-Invasive Prenatal Paternity (NIPP) testing: when you can test, how samples are collected, what can affect validity, and when results are issued.
If you have immediate questions regarding your specific situation, contact our team at +442046204341.
How does the science of NIPP work?
NIPP uses cell-free fetal DNA (cffDNA), which means small fragments of the baby’s DNA found in the mother’s blood. Collect the mother’s blood sample. Collect the alleged father’s cheek swab. Our laboratory compares thousands of DNA markers to determine whether the tested man is the biological father.

When can you take the test?
Book the test from 7 weeks of pregnancy. Confirm your dates first. If testing is done too early, the fetal fraction — the amount of baby DNA in the blood sample — may be too low for analysis.
What samples do you need?
Follow these steps:
- Order the Prenatal Paternity DNA Testing kit.
- Collect the mother’s blood sample with a trained professional.
- Collect the alleged father’s buccal swab.
- Send both samples to our laboratory promptly.

How accurate is NIPP?
Use NIPP if you need a safe prenatal option. It is 99.9% accurate when the alleged father is the biological father and 0% when he is not. Unlike invasive procedures such as amniocentesis or CVS, NIPP does not put the pregnancy at risk.
How do you protect sample quality?
Use the correct tubes. Send samples early in the week. Avoid delays. Our kits include:
- Specialist blood tubes
- Clear instructions
- Secure packaging

Are there any limitations?
Do not proceed with NIPP without checking eligibility. The test may not be suitable if:
- You are carrying twins or multiples
- You had a blood transfusion in the last six months
- You had a bone marrow or organ transplant
- You have certain cancers
Call +442046204341 if you need an alternative option.
When do results arrive?
Wait for results in 7 to 10 working days after the laboratory receives suitable samples. We issue results securely by email.
