How to check chromosomes before pregnancy

Chromosome testing before pregnancy requires a blood draw. Individuals with a history of unhealthy pregnancies or family genetic conditions can undergo chromosome testing prior to conception, in which chromosomes are extracted from venous blood, cultured, and analyzed for karyotype. Chromosomes are the genetic material in humans. Chromosomal abnormalities may have certain impacts on offspring development, so some individuals may need chromosomal testing. If chromosomal issues are detected, prenatal diagnosis or assisted reproductive technologies can be used to support conception. Not everyone needs chromosomal testing; it is recommended to perform such tests under the guidance of a physician.
