Have your NIPT test results and need help understanding them? DrPlus doctors can walk you through it.
Receiving your prenatal screening results can feel overwhelming, especially when the report is full of clinical terms like z-score, fetal fraction, and trisomy status. Most of that language exists for laboratory and clinical purposes, not because your result is complicated to understand once it is explained plainly.
This guide breaks down exactly what appears on a typical report, walks through a sample layout so you know what to expect, and explains what low-risk, high-risk, and inconclusive results actually mean for your pregnancy.
A DrPlus doctor reviews NIPT test results with a patient to explain findings clearly.
What Your NIPT Test Results Actually Show
Direct answer
NIPT test results report a risk classification, usually "low risk" or "high risk," for each chromosomal condition screened, such as Trisomy 21, 18, and 13. The report also includes the fetal DNA fraction (the percentage of fetal DNA in your blood sample) and, if requested, fetal sex. A low-risk result means the screened conditions were not detected. A high-risk result means an elevated probability was found and requires diagnostic confirmation, it is not itself a diagnosis.
Every report is structured around the same core idea: for each condition tested, the laboratory reports whether the statistical signal in your blood sample suggests low or high risk. The exact terminology and layout vary slightly between laboratories, but the underlying information is consistent.
Sample NIPT Test Results Report
To make this concrete, here is a simplified example of how they are typically presented. This is a sample layout for educational purposes only, not an actual patient report.

Notice that this sample shows a low-risk result for every screened condition, formatted clearly with a plain "low risk" or "high risk" label next to each one. Real reports also usually include reference information explaining sensitivity and specificity for each condition, along with a note that NIPT is a screening test rather than a diagnostic one.
Understanding a Low-Risk Result
A low-risk NIPT test result means the statistical analysis of your blood sample did not detect elevated signal for the screened conditions. This is reassuring, but it is worth understanding two things about what it does and does not mean.
01
Very high reassurance value
For the conditions actually screened, a low-risk NIPT result has a very high negative predictive value, meaning it is highly unlikely the condition is present when the result comes back low risk.
02
Only covers screened conditions
A low-risk result only speaks to the specific conditions included in your package. It does not rule out every possible genetic or structural condition, which is why routine ultrasound scans remain important.
03
Not a diagnostic guarantee
NIPT is a screening test. Even a low-risk result carries a small residual chance of a false negative, though this is rare for the primary trisomies screened.
Understanding a High-Risk Result
A high-risk NIPT test result means the statistical analysis detected an elevated probability for one or more of the screened conditions. This is understandably concerning, but it is important to know exactly what it means and what it does not mean.
01
Not a diagnosis
A high-risk result is a signal that further investigation is warranted. It is not confirmation that the baby has the condition. Diagnostic testing is required to confirm or rule out the finding.
02
Positive predictive value varies
The likelihood that a high-risk result reflects a true positive (the positive predictive value) depends on the specific condition and your individual baseline risk factors such as age. Your doctor can explain your specific PPV.
03
Diagnostic confirmation is the next step
Your doctor will typically recommend amniocentesis or chorionic villus sampling to confirm or rule out the finding definitively. Genetic counselling is often offered alongside this step.
Need help understanding your NIPT test results?
A DrPlus doctor can walk you through your report and explain exactly what it means for your pregnancy.
Occasionally, a report comes back inconclusive rather than low-risk or high-risk. This happens in a small percentage of cases, typically because the fetal DNA fraction in the sample was too low for reliable analysis.
Cause
What it means
Next step
Low fetal DNA fraction
Sample collected too early in pregnancy, or naturally lower fraction in this pregnancy
Repeat blood draw, usually 1 to 2 weeks later, at no additional charge
Sample quality issue
Technical issue during sample handling or transport affected analysis
Repeat blood draw with corrected handling process
High maternal BMI
Higher maternal BMI is associated with lower fetal DNA fraction on average
Repeat draw, sometimes at a slightly later gestational age
An inconclusive result is not itself a cause for concern about the pregnancy. It simply means the laboratory could not generate a reliable risk classification from that particular sample, and a repeat test is the standard next step.
What to Do After Receiving Your NIPT Test Results
01
Read the full report, not just the summary
Check the fetal DNA fraction, gestational age recorded, and results for every condition screened, not just the headline summary at the top of the report.
02
Book a doctor consultation
Whether your result is low-risk or high-risk, a short consultation with a doctor ensures you understand exactly what your specific report means and what, if anything, comes next.
03
Share results with your obstetrician
Your NIPT results should be added to your pregnancy records and discussed with the obstetrician managing your care, especially if a high-risk finding requires coordinated follow-up.
04
Consider genetic counselling if high-risk
For a high-risk result, genetic counselling helps you understand the specific condition, the accuracy of the finding, and the diagnostic testing options available to confirm it.

Common Questions About NIPT Test Results
At DrPlus, basic package NIPT test results are typically available within 7 to 10 working days, while the advanced package with microdeletion screening takes 10 to 14 working days. Results are delivered digitally and securely, and a doctor is available to explain them once they arrive.
Fetal DNA fraction is the percentage of cell-free fetal DNA present in your blood sample relative to your own DNA. A minimum fraction, typically around 4 percent, is required for the laboratory to generate a reliable result. A higher fraction generally supports greater confidence in the reported risk classification.
Like all screening tests, NIPT can occasionally produce a false positive or false negative, though this is uncommon for the primary trisomies screened given accuracy rates above 99 percent for Trisomy 21. This is exactly why a high-risk result always requires diagnostic confirmation before any clinical decision is made, and why NIPT is described as a screening test rather than a diagnostic one.
Yes. A DrPlus doctor is available to review your NIPT test results with you, explain the terminology used in your specific report, and advise on next steps regardless of whether the result is low-risk, high-risk, or inconclusive. This support is included with every NIPT test booked through DrPlus.
Yes, if you opt in to fetal sex determination, which is available as part of most NIPT packages. Since the test analyses fetal DNA including the sex chromosomes, gender can typically be reported from around week 10, considerably earlier than a reliable ultrasound reading, which is usually possible from 18 to 20 weeks.
