Watch our 30-minute webinar to learn about:
- Published findings from SMART, the largest prospective NIPT study with over 20,000 patients enrolled
- How SNP-based NIPT performed in a large, diverse, real-world environment compared to validation study results
- Potential impact of these findings on expanded NIPT screening guidelines
- Improving SNP-based NIPT performance with the use of artificial intelligence
Why choose Panorama for fetal genetic testing?
Clinical advantages of genetic testing for pregnancy:
- Panorama detects conditions that other tests cannot, including molar pregnancy, triploidy and vanishing twin.4
- Panorama screens for Down syndrome with an accuracy rate greater than 99%.*1,5-7
- Panorama is the only test that differentiates between pregnant person’s and fetal DNA, which helps avoid false positives and false negatives.1,5-9
- Panorama is the only NIPT that can assess zygosity and individual fetal fraction* in twin pregnancies.**10
- Panorama has a 22q11.2 deletion sensitivity of 83%. This common and potentially severe microdeletion impacts pregnancies equally regardless of maternal age.2
- Panorama can be performed for singleton, twin, egg donor, and gestational carrier pregnancies.9
Validated in SMART, the largest prospective NIPT study1-3
Findings from the SMART study have been published in the American Journal of Obstetrics and Gynecology

Recent ACOG guidelines support NIPT for all pregnancies1
- Recommends NIPT as an option to be “discussed and offered to all patients early in pregnancy, regardless of maternal age or baseline risk.”
- Endorses cfDNA as the “most sensitive and specific screening test for the common fetal aneuploidies.”
- Highlights unique advantages of SNP-based NIPT, including triploidy detection and unique twins capabilities such as zygosity detection and individual fetal fraction measurements.
Panorama’s SNP-enabled capabilities make every result matter
Vanishing twin detection4
Recognized by the American College of Obstetricians and Gynecologist (ACOG) as a major cause of NIPT false positives8
Maternal X mosaicism detection11
As patients age, mosaicism for a missing X chromosome becomes more common, and is another ACOG-recognized major cause of error in NIPT8
Triploidy detection4
As stated in ACOG practice bulletin 226, SNP-based NIPT (Panorama) is the only noninvasive method that can identify triploidy8

Clinically validated differentiation for twin pregnancies*
Zygosity detection10
Recognized by the International Society for Prenatal Diagnosis (ISPD) as an important element in evaluating NIPT results for twins12
Individual fetal fraction for dizygotic twins10;13
An important metric necessary to interpret the reliability of NIPT results; ACOG recognizes that, without this measurement, aneuploidy could go undetected if the affected twin has low fetal fraction8
Individual fetal sex10
Panorama has zero fetal sex errors in published validation studies for both singletons and twins5-7,10
Other conditions screened9
- Trisomy 21
- Trisomy 18
- Trisomy 13
- Sex chromosome trisomies (reported when seen)†
- 22q11.2 deletion syndrome (optional)†
Panorama can help clinicians triage twin pregnancies effectively*10,14-18
Panorama identified monozygotic twins with >99% sensitivity and specificity in a validation study.
While chorionicity can be reliably detected early in pregnancy, studies have shown that up to 19% of monochorionic pregnancies are incorrectly classified as dichorionic. Panorama allows clinicians to align their ultrasound findings with an early and accurate zygosity determination.
- Identifying a monozygotic twin pregnancy with Panorama can prompt earlier, targeted ultrasound assessments for chorionicity and associated complications.
- Knowing that a twin pregnancy is dizygotic reduces healthcare providers’ and patients’ concerns about twin-to-twin transfusion syndrome (TTTS).
Pregnancy management of twins is highly influenced by chorionicity; as such, Panorama’s zygosity determination can help healthcare providers determine an appropriate management plan.

Footnotes
*CA residents: Trisomies 21, 18, and 13, as well as fetal sex, are screened using Natera’s Vasistera NIPT or other approved NIPTs through the California Prenatal Screening program. Vasistera also assesses zygosity and individual fetal fraction in dizygotic twins. In California, Panorama is only offered as a supplemental NIPT for conditions not screened by Vasistera (for singleton pregnancies only).
** For dizygotic (nonidentical) twins only.
† For identical twins only.
