Your patients deserve early, accurate information on a wide range of serious chromosomal abnormalities—information that only the Panorama prenatal test can provide.
Panorama™ Prenatal Test provides superior coverage
and the highest accuracy of any other prenatal screening test.
The Next Generation in NIPT
Panorama is the only test that uses the advanced science afforded by SNPs to differentiate fetal DNA from maternal DNA and to determine the genotype of the fetus. This allows the Panorama test to report risk scores with extremely high accuracy across all conditions tested.
Other technologies do not separate out the maternal DNA from the fetal DNA—they simply count the total number of chromosomes and compare to a reference chromosome. With these counting or quantitative methods, inconsistent amplification during sequencing can make it difficult to measure the difference between the expected number of chromosomes and the observed number, leading to reduced accuracy.

Highest Accuracy of all NIPTs, even at Low Fetal Fractions
With the counting method used by all other NIPTs, accuracy falls when fetal fraction drops below 8%, even for Trisomy 21, which is the easiest trisomy to identify. Other technologies do not report the fetal fraction percentage, so physicians may not know when the accuracy of their patients’ results is impacted by low fetal fraction.
Panorama’s accuracy remains excellent even at fetal fractions as low as 4%, and fetal fraction percentage is always reported.
Accurate Results at 9 Weeks Gestational Age
While fetal fraction of DNA in the mother’s blood can vary greatly throughout gestational age, it does tend to be lower earlier in the pregnancy. By using SNP technology, the Panorama test is consistently accurate even at lower fetal fractions, and can be used as early as 9 weeks gestation.
Consistently High Accuracy Across All Chromosomes Evaluated
The Panorama test identifies Trisomy 21, Trisomy 18, Trisomy 13, and Monosomy X.
Comparison of NIPT Performance
You and your patients deserve the reassurance that comes from having the most accurate and comprehensive genetic screening information.
According to current American College of Obstetricians and Gynecologists (ACOG) guidelines, a non-invasive prenatal test should be offered as a first-line screening test for patients with an increased risk of fetal aneuploidy.
Clinical indications include:
- Advanced maternal age
- Ultrasound indicating increased risk of aneuploidy
- Abnormal serum screening
- Prior pregnancy with a trisomy
- Known parental balanced translocation
- Confirmed multiple-gestation pregnancy
- Egg donor or surrogacy
- Bone-marrow transfer recipient
