Test Description
Chromosome karyotype analysis in peripheral blood can directly show the band type on the chromosome, not only can detect the changes in the number of chromosomes, but also can observe the deletion, duplication, inversion, translocation and other structural abnormalities. The chromosome band level is 450 - 600.
Indications for Testing
- Multiple abortion, stillbirth and infertility in couples.
- Pregnant women with an elder age.
- Couples who have already given birth to children with chromosomal abnormalities, or both or one of them has a family history of genetic disease.
- Couples in which one or both partners has a suspected or known abnormality in chromosome number or structure pre-pregnancy examination.
- People who wish to undergo eugenic and eugenic examination.
Test Methods and Limitations
G-banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. It is useful for identifying genetic diseases (mainly chromosomal abnormalities) through the photographic representation of the entire chromosome complement.
