The advantages of this diagnostic test:
- Rapid-fast result to reduce mother’s anxiety
- Accurate-99% detection rate
A karyotype is an actual photograph of the chromosomes from one cell. Karyotypes are usually done using blood cells, fetal skin cells (from amniotic fluid or the placenta) and occasionally bone marrow cells. While a karyotype is used to confirm that a person has Down syndrome due to an extra chromosome number 21, it actually gives much more information. It is able to identify a wide range of chromosomal abnormalities including alterations in copy number (aneuploidy) as well as chromosomal rearrangements, such as translocations, deletion and inversion.
During pregnancy, the sample can either be amniotic fluid collected during an amniocentesis or a piece of the placenta collected during a chorionic villi sampling test (CVS). The amniotic fluid contains fetal skin cells which are used to generate a karyotype. In the end, the final karyotype test shows the total number of chromosomes, the sex of the person being studied, and if there are any structural abnormalities with any of the individual chromosomes. A digital picture of the chromosomes is generated with all of the chromosomes arranged by number. When diagnosing Down syndrome, the focus tends to be on the total number of chromosomes, but in reality, a karyotype gives you information on the number, the structure and many other facets of an individual’s chromosomes.
It detects aneuploidy for all 23 chromosomes.
There is no culture needed and it provides high resolution chromosomal profiling that enables the determination of the cause of pregnancy loss compared to conventional karyotyping.
Who should go for KaryoCheck test?
- Women with recurrent miscarriage
- Parent(s) with birth defect history and/or abnormal phenotype
or functional defect
Thalassaemia is an inherited genetic disorder of the red blood cells that affects the production of haemoglobin and causes anemia. Thalassaemia causes different degrees of anemia, which can range from insignificant to life threatening.
ThalaCheck® is a DNA test to detect mutation for Thalassaemia in the fetus. It allows Thalassaemia carrier parents to check the Thalassaemia status of their baby as early as ≥11 weeks of pregnancy.
