Why choose AURORA

---

A Offer your patients a better service compared to invasive prenatal screening tests. AURORA is a safe, reliable, quick and early test. In fact, it differs from invasive prenatal diagnostic tests (amniocentesis, chorionic villus sampling, cordocentesis) for its reliability (test sensitivity higher than 99.9%  for trisomy 21 and trisomy 18) and for its non-invasiveness, ensuring absolute absence of miscarriage risks.

B  Offer your patients a  better service, also compared to other  non-invasive prenatal screening tests:

1. Other tests conduct biochemical investigations on maternal blood or ultrasound measurements, while the AURORA test directly analyzes the fetal DNA circulating in maternal blood, with a reliability rate of 99.9% for the main trisomies.
   Example of technical performance for one of the AURORA test procedures compared to alternative tests.
   
   
2. Other non-invasive prenatal tests show high error frequencies (rates of false positives, cases in which the test detects a chromosomal abnormality that is not actually present in the fetus).
   Example of technical performance for one of the AURORA test procedures compared to alternative tests.
   
   
3. Easy-to-read results with two alternatives: aneuploidy "detected" or aneuploidy "not detected".

Technological innovation

The tests are performed in California, USA, at the Illumina Inc. labs, using the cutting edge technology of massive parallel sequencing (MPS) of the entire human genome. It has the following advantages:

Reference table

Chromosome	Sensitivity %	False negatives %	Specificity %	False positives
Trisomy 21	99.14	0.86	99.94	<0.1
Trisomy 18	98.31	1.69	99.90	0.1
Trisomy 13	98.15	1.85	99.95	<0.1
Monosomy x	95	5	99.0	1
xxx-xxy-xyy	Rare aneuploidies, unmeasurable accuracy
Sex determination - xx	97.6	2.4	99.2	0.8
Sex determination - xy	99.1	0.9	98.9	1.1
Trisomy 9	Rare aneuploidies, unmeasurable accuracy
Trisomy 16	Rare aneuploidies, unmeasurable accuracy
Microdeletions	Rare aneuploidies, unmeasurable accuracy

Legend:
Sensitivity  = power of the test, expressed in percentage terms, to identify the presence of a aneuploidy

Specificity = power of the test, expressed in percentage terms, to exclude those who have not developed an aneuploidy

False negatives = cases in which the test does not detect a chromosomal abnormality present in the fetus

False positives = cases in which the test does not detect a chromosomal abnormality which is not actually present in the fetus

Better performance

AURORA has the lowest rate of repeat testing than other tests on fetal DNA

Excellence of the Service

The AURORA service simplifies gynaecologists’ tasks compared to any other test:

• maternal blood sampling can be done, at the request of the patient, at her domicile;
• medical reports accompanied by a technica l report by a qualified geneticist;
• the kit packaging and shipment procedures are handled by Sorgente Genetica, thus relieving the gynaecologist’s office/medical centre of the performance of such activity;
• dedicated customer support and daily shipments.
