Many parents compare NIPT vs first-trimester screening when choosing prenatal tests. NIPT and first-trimester screening are both prenatal tests that assess the risk of chromosomal conditions. NIPT uses fetal DNA from the mother’s blood and is more precise, while first-trimester screening combines blood tests and ultrasound measurements. Your healthcare provider can assist in choosing the most suitable option.
Early in pregnancy, you might be offered various screening options to evaluate your baby’s development. Two common ones are the NIPT test and first-trimester screening. Both aim to provide helpful information, but they differ in how they work, when they are performed, and in their accuracy. Knowing these differences can help you select the option that best suits your needs.
What Is First-Trimester Screening?
First-trimester screening is a combination of:
- A blood test
- An ultrasound measurement called nuchal translucency
It is typically done between 11 and 14 weeks of pregnancy.
This screening estimates the likelihood of conditions such as:
- Down syndrome
- Trisomy 18
What Is the NIPT Test?
NIPT is a blood test that checks cell-free fetal DNA in the mother’s bloodstream. It can be done earlier—around 10 weeks—and provides a more accurate estimate of the chances of certain chromosomal conditions.

Key Differences Between NIPT and First Trimester Screening
Understanding the differences between NIPT and first trimester screening can help you select the option that best fits your needs and preferences during pregnancy.
| FEATURE |
NIPT |
FIRST-TRIMESTER SCREENING |
| Accuracy | Over 99% accuracy for Down syndrome | Lower accuracy, higher chance of false positives |
| Timing | From 10 weeks of pregnancy | Between 11–14 weeks of pregnancy |
| Method | Blood test only | Blood test combined with ultrasound |
| Purpose | Screening test (not diagnostic) | Screening test (not diagnostic) |
NIPT provides earlier and more accurate screening, while first trimester screening combines ultrasound and blood tests to offer a broader early assessment—both are valuable options depending on your needs.

Which Option Might Be Right for You?
Choosing between NIPT and first-trimester screening usually depends on your preferences, timing, and the kind of information you want.
| If you prefer… | NIPT may be a better fit | First Trimester Screening may be a better fit |
| Earlier results | ✔ Available from 10 weeks | — |
| Higher accuracy | ✔ More precise screening results | — |
| Non-invasive simplicity | ✔ Blood test only | — |
| Combined ultrasound + screening | — | ✔ Includes ultrasound measurement |
| Publicly funded option (in some cases) |
Sometimes (depending on province/risk level) | ✔ More commonly covered |
| A more traditional screening approach | — | ✔ Standard option in many pregnancies |
Both options give useful insights into your baby’s development. NIPT provides earlier and more accurate results, while first-trimester screening offers a combined approach that includes ultrasound and is often part of routine care.
Can You Do Both?
In most cases, you will not need both tests.
Your healthcare provider usually suggests the best option for your situation.
Is Gender Determination Part of These Tests?
While NIPT can reveal your baby’s gender, that is not the main goal of either test. If discovering your baby’s gender is your main focus, there are other options better suited for that purpose.
Other Ways to Find Out Your Baby’s Gender
If gender determination is your focus, there are options designed specifically for that experience.
| Option | When Available | What to Expect |
| Early Reveal Blood Test | From 7 weeks | Early indication through a simple blood test |
| Gender Reveal Ultrasound | From 16 weeks | Visual confirmation while seeing your baby in real time |
While prenatal tests focus on your baby’s health, these options aim to make gender discovery a more meaningful and memorable experience.
