There are no requirements for this test, no need to fast. Neither is an appointment necessary, blood draws are performed from 8:00h – 10:30h from Monday to Friday.
The results are delivered after 15 days.
The karyotype indicates whether the chromosomes are organized normally (in 23 pairs) and that they all have the right length and position, that is, that there are no deletions (shortening and therefore lack of part of the genetic material), translocations or inversions.
Many of these alterations provide a normal phenotype, that is, the individual has no clinical manifestations and is perfectly healthy. However, when it comes to having descendants, the individual does transmit this alteration to his or her children, in some cases causing incompatibility with life, and therefore causing repeated miscarriages or infertility. This type of alterations are relatively frequent in the population, being found in 1 or 2 individuals of each 1000. That is why karyotyping is often performed on couples who are unable to have children, either because of repeated miscarriages or other reasons. The percentage of offspring to which it is transmitted will depend on each particular case.
