How to read the report of AURORA
The results of the AURORA test are provided in clear and easily understandable terms. The report will simply include a reference to aneuploidy "detected" (positive result) or aneuploidy "not detected" (negative result). The AURORA service makes available genetic counselling to gynaecologists, so as to best assist patients in interpreting data, especially in cases of aneuploidy "detected" or "suspected".

If the result of the test is POSITIVE
It means that a aneuploidy has been detected for one of the chromosomes examined. In this case it is advisable to perform an invasive prenatal diagnostic tests, such as Chorionic Villus Sampling or Amniocentesis to confirm the pathological result. An AURORA geneticist will be available for a free consultation, to explain in detail the test results and recommend further tests to be performed.
If the result of the test is NEGATIVE
It means that no aneuploidies have been detected for the chromosomes examined. The reliability of the test result is higher than 99.9% for Trisomy 21 and Trisomy 18, and slightly lower for the other aneuploidies investigated. This result, however, does not ensure that no such anomalies are present in the fetus.
In some cases, the test may not produce an optimum result. Should this be the case, we will ask the expectant mother to take a new blood sample in order to repeat the test. In other cases, the test could provide an ambiguous result, which can be compatible with the presence of fetal chromosomal aneuploidy (borderline result). If so, it will be recommended to confirm the result by invasive prenatal diagnosis.
