Description
Safe T21 Express Prenatal Screening
Safe T21 Express adopts the latest and patented Non-Invasive Prenatal Testing Technology (NIPT) for the screening of fetal chromosomal aneuploidies. The test utilizes Next Generation Sequencing followed by bioinformatics analysis on both maternal DNA and cell free placental DNA found in maternal blood. The detection of fetal chromosomal aneuploidies including Down Syndrome (T21), Edwards Syndrome (T18), Patau Syndrome (T13), Sex Chromosome Aneuploidies and microdeletion / microduplication all in ONE test is now made possible. Compared to the traditional screening methods based on nuchal translucency or maternal age, Safe T21 Express is more sensitive, reliable, accurate and informative.
Advantages of Safe T21 Express Prenatal Screening：
- High accuracy for common chromosomal abnormalities >99%
- Safe, non-invasive, and non-intrusive
- Testing results unaffected by maternal age
- Testing can be done as early as 10 weeks gestation
- Report available within five working days
Suitable for:
- Singleton : ≥10 weeks
- Twins or Fetal Reduction : ≥12 weeks
- Triplets: ≥14 weeks
- IVF Pregnancy
Standard Panel Testing Items (14 items)
The test screens for 14 validated conditions. In alignment with international guidelines, this panel is the recommended choice for most mothers.
Trisomies
A trisomy is a chromosomal condition characterised by an additional chromosome. The disorders below are the most common forms of trisomy.
- Trisomy 21
- Trisomy 18
- Trisomy 13
Sex Chromosomes Aneuploidies
The presence sex chromosomes determine the gender of your babies, XX for female and XY for male. The sex chromosomes occur in abnormal numbers can lead to severe health issues.
- Turner Syndrome
- Jacob’s Syndrome
- Klinefelter Syndrome
- Triple X Syndrome
Microdeletion Syndromes
Microdeletion occurs when a small segment of the chromosome is deleted or duplicated. It can only be detected by advanced technology with high resolution.
- 1p36 Deletion Syndrome
- 1 Deletion Syndrome
- Angelman Syndrome
- Cri-du-chat Syndrome
- DiGeorge Syndrome
- Langer-Giedion Syndrome
- Prader-Willi Syndrome
- Advanced Panel Testing Item
Advanced Panel Testing Item (152 items)
The test screens for chromosomal aneuploidies of all 23 pairs of chromosomes, including trisomies and at least 126 microdeletions/ microduplications with size greater than 3Mb that has recorded on the international databases: OMIM, Decipher and Orphanet.
Trisomies
A trisomy is a chromosomal condition characterised by an additional chromosome. Advanced panel screens for trisomies of all chromosome.
Sex Chromosomes Aneuploidies
The presence sex chromosomes determine the gender of your babies, XX for female and XY for male. The sex chromosomes occur in abnormal numbers can lead to severe health issues.
Microdeletion Syndromes
Microdeletion occurs when a small segment of the chromosome is deleted or duplicated. Advanced panel screens for at least 126 microdeletions/ microduplications. To view the full panel, please contact us .
Safe T21 Express utilizes Next Generation Sequencing followed by bioinformatics analysis on both maternal DNA and cell free placental DNA found in maternal blood. The results are generated by comparing the allelic ratios of the amplified fragments derived from the targeted chromosome of both mother and fetus. If the fetus is aneuploid, allelic ratios on the aneuploid chromosome are skewed in comparison with other, non-aneuploid chromosomes.
