Karyotype

A blood test examining the number and structure of chromosomes.

Genetics

A karyotype photographs all 46 chromosomes to detect missing, extra or rearranged material. It is offered after recurrent miscarriage, in severe male factor infertility, and where a family history suggests a chromosomal condition. Finding a balanced translocation in a parent explains many repeated losses and opens the option of PGT-SR.

Also known as: chromosome test, chromosomal analysis
