With Panorama’s high sensitivity and low False Positives, >99% of women who screen positive for Down syndrome will be carrying a fetus with Down syndrome.2

WHY NIPT? Helps avoid unnecessary chorionic villus sampling and amniocentesis.

For every 20 women who show High Risk for Down syndrome with biochemical screening, only one (5%) will be carrying a fetus with Down syndrome,1 and many who are not carrying a positive fetus will have invasive procedures.

Panorama is the only NIPT that uses the advanced science afforded by SNPs (single nucleotide polymorphisms) to differentiate the maternal from the fetal cell-free DNA (cfDNA) to determine the genotype of the fetus.2

PANORAMA The next generation in NIPT

TURNAROUND - MOST RESULTS REPORTED IN LESS THAN 10 DAYS

PANORAMATM IS THE MOST ACCURATE, COMPREHENSIVE NON-INVASIVE PRENATAL SCREENING TEST WHICH CAN HELP YOU PROVIDE YOUR PATIENTS WITH THE REASSURANCE THEY NEED DURING THEIR PREGNANCY.

THE VALUE OF PANORAMA OVER OTHER NIPTS

COMPARISON WITH OTHER NIPTS WHICH ARE BASED ON COUNTING TECHNOLOGIES

Panorama Test Other NIPTs

Uses more robust data – the actual DNA from the mother – to “subtract out” the mother’s cfDNA from the fetus and does not require use of a

reference chromosome

Do not separate out the maternal from the fetal cfDNA – they simply count cell-free DNA strands and compare to a reference chromosome

>99% combined accuracy for T21, T18, and T13, male and female, and triploidy at levels as low as 4% fetal fraction in published clinical trials Up to 25% false negatives at fetal fraction of 4-8%

Always reports fetal fraction Most do not report fetal fraction

Always reports risk score for monosomy X - an aneuploidy that is more common at mid trimester than T13, T18 and T21 combined

Some only call monosomy X when found, and do not confirm the absence of monosomy X

Provides every patient with a Personalised Risk Score May include grey areas like “aneuploidy suspected”

Identifies triploidy, a major cause of miscarriage Unable to detect triploidy

22q11.2 deletion syndrome screening which occurs in approximately 2,000 births can be requested Most do not offer 22q11.2 deletion syndrome screening

Panorama uses a proprietary, patented algorithm, called Natera’s NATUS, to take into account the actual DNA of the mother, and uses that to deduce the fetal genotype. The result is a report that provides a personalised risk score. Through the use of this science, Panorama is accurate at fetal fractions as low as 4%3, and can be used earlier in the pregnancy than other NIPTs. The NATUS algorithm incorporates over 3,000 SNPs per chromosome evaluated, allowing Panorama to select SNPs that are not impacted by ethnicity.

Panorama delivers more accuracy than other NIPTs. There are several versions of NIPT available for you to offer your patients. However, Panorama’s accuracy remains excellent even at fetal fraction (ff) as low as 4%. The accuracy of all other NIPTs that use quantitative counting methods, falls markedly when fetal fraction drops below 8%. This is true even for T21, typically the easiest trisomy to identify.3,5

– In the non-Panorama data set (average gestational age 15 weeks), 10-15% of women had fetal fraction between 4-8%. – Panorama research determined that 25% of women at gestational ages between 9-14 weeks had fetal fraction between 4-8%.3

– In addition, Panorama is able to report both high sensitivity and specificity for all chromosomes evaluated, even X and Y.6,7,8

MICRODELETION SYNDROMESPanorama now offers a screen for the most common and severe microdeletion syndromes, in addition to its basic screen for T21, T18, T13, tripoidy and sex chromosome abnormalities.

Why Screen for Microdeletion Syndromes?

• Are common and can be severe• Carry equal risk across all maternal ages• Often undiagnosed• Respond to early childhood intervention

Scientifically Validated

Microdeletion validation has been completed by Natera™ with 469 samples, including 110 confirmed positives. Accuracy of performance has been validated at fetal fractions as low as 3.8%.

Limitations of the Test

Panorama does not screen for all microdeletion syndromes. Performance specifications reflect presence or absence of the entire targeted region. Patients who screen positive should be offered a follow-up invasive procedure to confirm diagnosis.

How to order Panorama’s Microdeletion Screening

You may order the Panorama pre-natal screen alone or the extended panel with one of these two options:

• 22q11.2 Deletion syndrome (also known as DiGeorge syndrome) alone

• 22q11.2 deletion, Prader-Willi, Angelman, Cri-du-chat and 1p36 deletion syndromes

Please Note: Microdeletion screening cannot be ordered separately from the Panorama prenatal screen.

REASSURANCE The Panorama test provides:

Comprehensive clinical coverage.• Identifying chromosomal abnormalities T21, T18, T13, Monosomy X and Triploidy• Comprehensive microdeletion screening including 22q11.2 deletion syndrome

(also known as DiGeorge syndrome)

Superior accuracy over other NIPTs available and serum screening.• Consistently high accuracy across all chromosomes evaluated• Highest levels of sensitivity and lowest levels of false positives of all NIPTs, even

at low fetal fractions• Accurate results as early as 9 weeks gestation

Excellent customer support.

• Supplemental information sheets can be provided with positive reports that the provider can refer to when discussing the findings with the patient

• Turnaround - most results reported in less than 10 days

A safe, convenient method that can help you avoid invasive fetal testing.• Uses a simple blood sample from the mother

request /consent form give to the patient to bring to a Melbourne IVF Clinic

• Patient to telephone a Melbourne IVF Clinic to book a blood collection

• Results will be sent directly to you the requesting doctor

• If there is a positive result Melbourne IVF will telephone you to ensure you have seen the result and explained the requirement and further testing for the patient.
