Since it uses blood drawn from mothers at 10 weeks of pregnancy or later, it has no burden on the baby and mother, and allows you to test for chromosomal abnormalities of the baby in your belly safely, securely, and at low cost.
seeDNA's Non-Invasive Prenatal Testing does not require high testing costs, age restrictions, or anxiety about complex testing.
You can easily receive world-top level testing.

Non-Invasive Prenatal Testing
Using the latest medical technology, we analyze tiny amounts of fetal DNA contained in maternal blood to check for the presence of genetic diseases caused by chromosomal abnormalities.
It is a screening test to confirm if the baby in the belly has chromosomal abnormalities that cause congenital diseases or disorders.
It is a common test already taken by 75% of mothers in medically advanced European countries.
Simple & Accurate
It is a simple test just by drawing blood at seeDNA's partner medical institutions. There is no age limit for testing.
Compared to maternal serum marker testing, which is said to have an accuracy of about 80%, this test has a significantly higher accuracy rate of 99.1%.List of Partner Clinics Nationwide for Blood Collection
Fast & Affordable
You can early detect not only disorders and diseases of the baby in the belly but also the risk of miscarriage from 10 weeks of pregnancy.
Results will be delivered in as short as 6 days after the blood sample reaches us.
Blood collection fees at partner clinics are free.
In the event of a high-risk result, we will fully bear the cost of confirmatory testing.
Safe & Secure
A safe test that only requires drawing 10 mL of maternal blood, posing minimal burden on both the mother and the baby. The biggest feature is that there is no risk of miscarriage or infection.
You can welcome childbirth with peace of mind by knowing the risk of a wide range of hereditary diseases, including microdeletions across all chromosomes and gender, in addition to numerical abnormalities of specific chromosomes.

If you submit the receipt from the amniocentesis/CVS and a 20 mL blood sample, we will fully bear the confirmatory diagnosis cost.
Free Blood Draw
seeDNA will also fully bear the blood draw fees.
→ We handle all reservations for partner medical institutions. It is an easy blood draw with no payment at the counter or return shipping of the kit required.
→ There are no restrictions on blood draw hospitals. We also cover fees if blood is drawn at institutions other than partner clinics※1. Drawing blood at your primary care hospital is also OK※2.
※1: For payment of blood draw fees at non-partner clinics, submission of the medical bill statement and receipt issued by the clinic is required.
※2: You need to return the kit yourself.

Free Retest & Refund Guarantee
In the unlikely event that a precise test cannot be performed due to low fetal DNA amount in the blood, the kit resending fee, retesting fee, and blood draw fee are all free.
→ If you decline the retest, we will partially refund the test cost.
The target of free retest or partial refund guarantee is gestational age from 10 to 16 weeks at the time of blood draw... Without submitting a certificate, you cannot use the free retest or partial refund guarantee.

Pros and Cons
of NIPT
Although NIPT can find genetic diseases such as Down syndrome with high accuracy,it is conducted as a 'clinical study', so there is a limit to accuracy where results cannot be finalized. Please check the pros and cons of taking NIPT that other hospitals or clinics do not tell you.
Pros
Accuracy
With only a single blood draw, you can detect genetic diseases caused by chromosomal abnormalities with high accuracy that cannot be found by conventional ultrasound or blood tests.
Safe & Simple
There is no risk of miscarriage, making it a 100% safe test for the baby in the belly and the mother. The test is performed with only a 10 mL blood draw at partner medical institutions nationwide, allowing you to easily take the test without traveling to a distant hospital.
Early Testing
If the test result is high-risk, it gives you time to discuss with family and prepare mentally for moving on to the free confirmatory diagnosis we provide.
Cons
Screening Test
NIPT is a screening test that evaluates the risk for specific chromosomal abnormalities as high risk, low risk, or pending※1. It is not a diagnosis to finalize fetal diseases in clinical practice.
※1: Testing is conducted at partner laboratory, Taiwan Integrated Genomics Solutions (formerly Yourgene). It analyzes fetal genes to calculate the risk for specific genetic diseases.
High Cost
Because cutting-edge testing technologies like next-generation sequencing are used, it is more expensive than conventional ultrasound. If a risk of chromosomal abnormality is found, confirmatory testing incurs costs, but seeDNA covers it in full.
Limit of Test Items
Among many genetic diseases, it only checks for genetic diseases caused by chromosomal abnormalities that are test targets. Therefore, there may be potential risks of genetic diseases outside the test items.
Test Accuracy
Since NIPT is a screening test that reports the risk for each genetic disease as high risk, low risk, or pending, we cannot present accuracy that finalizes the disease like clinical tests in general medical practice.
The results shown here arevalues calculated assuming high-risk/low-risk results as positive/negative respectively.
| Negative Predictive Value for Low Risk | Positive Predictive Value for High Risk | |
|---|---|---|
| Trisomy 21 Down Syndrome | Trisomy 21 Down SyndromeNegative Predictive Value for Low Risk 99.99% or higher | Trisomy 21 Down SyndromePositive Predictive Value for High Risk 98.4% |
| Trisomy 18 Edwards Syndrome | Trisomy 18 Edwards SyndromeNegative Predictive Value for Low Risk 99.99% or higher | Trisomy 18 Edwards SyndromePositive Predictive Value for High Risk 95.3% |
| Trisomy 13 Patau Syndrome | Trisomy 13 Patau SyndromeNegative Predictive Value for Low Risk 99.99% or higher | Trisomy 13 Patau SyndromePositive Predictive Value for High Risk 92.8% |
