Panorama vs. Harmony test: What expecting parents should know

Choosing a prenatal screening test isn’t just a box to check — it can shape how you plan, prepare, and move forward during pregnancy. The Panorama and Harmony tests are two of the most widely used non-invasive prenatal testing (NIPT) options, and while they may seem similar on the surface, they’re built differently, screen for different things, and serve slightly different needs.

In this Panorama vs. Harmony test comparison, we’ll walk you through how the two tests stack up — what they screen for, how accurate they are, when you can take them, and how costs and insurance coverage might influence your decision.

What is the Panorama test?

Source: Natera

Panorama is an NIPT developed by Natera, a company known for its advanced DNA-based genetic testing.

Unlike most NIPTs, Panorama uses SNP-based technology, which allows it to distinguish fetal DNA from maternal DNA with greater precision. This reduces interference from the mother’s genetic material and helps provide clearer results, even when fetal fraction is low (which can happen early in pregnancy or in higher-risk cases).

Panorama screens for a range of chromosomal conditions, including common trisomies, certain sex chromosome abnormalities, and some select microdeletions.

What is the Harmony test?

Harmony is an NIPT developed by Roche, a leading healthcare company known for its broad range of diagnostic solutions.

It uses a targeted sequencing method called DANSR (digital analysis of selected regions) that focuses on specific chromosome regions linked to common genetic conditions, such as trisomies 21, 18, and 13. Harmony’s proprietary FORTE algorithm analyzes the proportion of DNA fragments from these chromosomes to estimate the risk of abnormalities.

Harmony screens for key chromosomal conditions and is validated for use in various pregnancy types, including singleton, twin, and egg-donor pregnancies.

Harmony vs. Panorama: 4 key differences

Choosing the right prenatal genetic test depends on what matters most for you and your pregnancy. To make that clearer, we’ll examine Panorama and Harmony across four key areas:

1. Conditions screened

2. Accuracy

3. Timing and turnaround

4. Cost and insurance coverage

1. Conditions screened

When it comes to what each test screens for, Panorama and Harmony share some common ground but also have key differences that may influence your choice.

Harmony focuses primarily on the most common trisomies:

• 21 (Down syndrome)

• 18 (Edwards syndrome)

• 13 (Patau syndrome)

It offers the option to add screening for sex chromosome conditions and microdeletions, but these aren’t covered by the standard test. This approach is appealing if you prefer to start with a focused panel and then expand based on your doctor’s recommendations or personal preferences.

Panorama, on the other hand, offers a broader screening panel. Besides the standard trisomies, it also screens for:

• Triploidy (an extra set of chromosomes)

• Sex chromosome aneuploidies like Turner syndrome (Monosomy X) and Klinefelter syndrome

• Select microdeletions, including 22q11.2 deletion syndrome, which can affect development and immune function

This extensive coverage can provide more comprehensive insights without the need for additional testing.

Ultimately, your decision on which test’s screening panel fits best should reflect how much information you want upfront, your pregnancy risk profile, and discussions with your healthcare provider about which conditions are most relevant for you.

2. Accuracy

Source: Roche

Both Panorama and Harmony are widely trusted by healthcare providers, but their different technologies lead to subtle performance differences, especially in early or complex pregnancies.

Panorama offers:

• Sensitivity above 99% for detecting Down syndrome (trisomy 21), trisomy 13, triploidy, and fetal sex

• High sensitivity for trisomy 18 (96.4%) and monosomy X (92.9%)

• Specificity consistently over 99%, minimizing false positives

• Reliable results even when fetal DNA levels are low (around 4%), reducing inconclusive or inaccurate outcomes

• Clinical sensitivity of about 83% for select microdeletions, including 22q11.2 deletion syndrome

Harmony performs well with:

• Detection rates over 99% for trisomy 21

• Exceptionally low false-positive rate (under 0.1%)

• Validation across various pregnancy types, including twins and egg-donor pregnancies

• Screening for sex chromosome abnormalities and 22q11.2 deletion syndrome, though with lower sensitivity for microdeletions compared to Panorama

Because Panorama isolates fetal DNA using SNP technology, it tends to maintain strong accuracy even when fetal DNA levels are low or other factors complicate the pregnancy. Harmony is highly accurate for most pregnancies but may be less reliable when fetal DNA levels are very low, making Panorama a reassuring choice.

3. Timing and turnaround

When you can take your NIPT and how quickly you get results can make a real difference, especially if you’re anxious, planning your next steps, or coordinating follow-up care.

Panorama can be performed as early as nine weeks into pregnancy. This earlier testing window can be a big plus for those with a history of genetic conditions or other high-risk factors, giving more time for confirmatory testing or specialist visits if needed.

Harmony becomes available slightly later, starting at 10 weeks of gestation. For some, that one-week difference may not matter, but it can feel significant if you’re eager for early answers.

When it comes to the turnaround:

• Panorama uses a complex SNP-based analysis, so it’s typically expected that you’ll receive results in 5–7 calendar days. However, delays can happen due to low fetal DNA levels, sample quality, or lab workload, and occasionally, a redraw might be requested.

• Harmony results usually take 7–10 business days, with similar potential for processing delays due to the same factors.

If getting tested as early as possible is a priority, Panorama offers a slight timing advantage. On the other hand, both tests provide results within about one to two weeks, helping you move forward with your pregnancy plans with reliable information.

4. Cost and insurance coverage

The cost of NIPTs like Panorama and Harmony varies widely based on insurance and test options.

Panorama tends to be pricier due to broader screening. Natera reports that about two-thirds of insured patients pay little to nothing out of pocket. Self-pay prices usually range from $249 to $349, with financial assistance sometimes lowering costs to as little as $149. However, some patients report higher bills depending on insurance and billing practices.

Harmony’s pricing isn’t publicly detailed, so patients should consult their healthcare providers before testing to avoid surprises. Out-of-pocket costs for Harmony can also vary widely, sometimes reaching several hundred dollars, though self-pay rates may be lower if billed directly.

Because billing can be confusing and insurance denials are common, contacting the test provider directly to ask about cash pricing or financial assistance programs can often reduce costs and help avoid unexpected charges.

Panorama or Harmony test: Which one is right for you?

Choosing between Panorama and Harmony comes down to what matters most to you. To help you weigh your options, here’s a quick rundown comparing key aspects of Panorama and Harmony:

Keep in mind, these tests screen for specific genetic conditions but don’t capture all possible risks. If you want a more complete picture of your baby’s potential inherited risks, preconception genetic screening leveraging whole-genome sequencing (WGS) is an option worth exploring.

Nucleus offers an advanced WGS carrier screening test that is performed on parents, not the baby. By sequencing both parents’ genomes, Nucleus identifies risks for inherited genetic conditions that could be passed on to the baby, including many that aren’t covered by prenatal tests.

Nucleus: A closer look at your family’s genetic health

NIPTs like Panorama and Harmony can tell you about a baby’s risk for certain conditions, but they don’t tell you much about what you might pass down.

Nucleus sequences nearly 100% of your genome and screens for over 900 inherited conditions — including cystic fibrosis, Tay-Sachs, muscular dystrophy (MD), and many others not typically covered by standard prenatal tests. Plus, you get this information in clear, easy-to-understand reports, so you don’t need a genetics background to interpret your results.

For couples who want a fuller picture of their baby’s potential genetic health, Nucleus offers a deeper layer of insight — one focused on what you carry, not just what’s detected during pregnancy.
