ad. 26. Is initial karyotyping with cells from a chorionic villus sampling possible in one day?
For a quick assessment targeting techniques, aimed at chromosomes 21, 18, and sex chromosomes, can be used. Most widely used are FISH and QF-PCR. Much more precise and a faster method is the direct overnight karyotyping technique, which allows for initial assessment of all chromosomes with the use of the material from a chorion.
A sample from chorionic villus sampling or amniocentesis might also be sent to assessment with the use of the comparative genomic hybridization (CGH) by a geneticist cooperating with our centre. The CGH results are available within a week.
At our centre, we offer a wide range of examinations and methods, their choice depends on the patient’s will, geneticist’s suggestion and a technical possibility to collect a sample.
