introduction
bgi vista™ chromosome sequencing uses ngs-based low coverage whole genome sequencing (wgs) to help detect chromosome abnormalities before or during pregnancy. testing can be performed on a variety of different sample types.
bgi vista™ chromosome sequencing is especially suitable for:
- individuals or couples who want to confirm the high-risk screening test results, such as maternal serum screening (mss) or non-invasive prenatal testing (nipt)
- individuals or couples who have suffered from repeated miscarriage or who have had a child who suffers from a genetic condition
- individuals or couples who have had abnormal ultrasonography results, but with negative cgh, snp results
- anyone suspected of belonging to a population which is at higher risk of chromosomal abnormality or patients who want to understand if a chromosome abnormality was a factor in a miscarriage
ta time:
12 working days
sample:
abortion tissue, core blood (gestation week >12 weeks), peripheral blood, dna and amniotic fluid.
technology:
low coverage wgs
what conditions can bgi vista™ chromosome sequencing detect?
- triploidy
- aneuploidy for all chromosomes
- deletions or duplications
why choose bgi vista™ chromosome sequencing?
- fully screening for 24 chromosomes with accuracy of 99%
- having sensitivity of 土 5kb
- offering automated analysis for more accurate results
- providing the most comprehensive and up-to-date database for results analysis
- reducing a patient’s emotional burden and information from the results can improve the chances of a future successful pregnancy.
note: this test is considered a screening test, not a diagnostic test. before making any treatment decisions, all patients should discuss their results with their healthcare provider, who can recommend confirmatory, diagnostic testing where appropriate. this testing service has not been cleared or approved by the us fda and is not available in the usa.
