Groken Non-invasive Prenatal Screening (NIPS)
-
Our high-quality, affordable NIPS can detect fetal chromosomal abnormalities as early as 10 weeks, for all pregnant patients.
-
Groken NIPS quickly analyzes cell-free DNA (cfDNA) to assess whether a singleton or twin pregnancy is at increased risk for the three most common chromosomal disorders on chromosomes 21, 18, and 13.
-
Add optional microdeletion and sex chromosome analysis at no additional charge, or pair with carrier screening for even more insights.
Groken NIPS detects:
-
Trisomy 21 (Down syndrome)
-
Trisomy 18 (Edwards syndrome)
-
Trisomy 13 (Patau syndrome)
And we detect five clinically significant microdeletion regions to screen for syndromes that may be undetectable by ultrasound and other early screening technologies.
Microdeletions detected:
-
1p36 deletion syndrome
-
DiGeorge syndrome (22q11.2 deletion syndrome)
-
Angelman/Prader-Willi syndrome (15q11.2 deletion syndrome)
-
Cri du Chat syndrome (5p15.2 deletion)
-
Wolf-Hirschhorn syndrome (4p16.3 deletion)
We also Predict fetal sex as early as 10 weeks and simultaneously detect aneuploidies to determine the risk of sex chromosome disorders.
Aneuploidies detected:
-
Turner syndrome (monosomy X)
-
Triple X syndrome (47,XXX)
-
Klinefelter syndrome (47,XXY)
-
Jacob’s syndrome (47,XYY)
Lowest published failure rate in the industry
Our technology, which uses whole-genome sequencing, offers the lowest published failure rate in the industry, 0.1%.3-7
Positive predictive value (PPV)
-
Every positive report contains a PPV for chromosomes 21, 18, and 13
-
PPV is calculated for each patient using individual maternal age and gestational age
Fetal fraction
-
Each result report includes fetal fraction, the percentage of fetal DNA (placental cell-free DNA) present in the sample. Invitae’s technology is optimized to handle samples at the low end of the fetal fraction rate to deliver more accurate results.
Performed in the USA
-
The Groken non-invasive prenatal screen was developed by, and its performance characteristics were determined by Verinata Health, Inc. a wholly owned subsidiary of lllumina, Inc. The VHI laboratory which located in the USA is CAP-accredited and certified under the Clinical Laboratory Improvement Amendments (CLIA) as qualified to perform high complexity clinical laboratory testing.
