The Karyotype is your personal 'genetic blueprint.' This foundational test analyzes a blood sample to create a detailed picture of your 46 chromosomes, checking their size, shape, and number. This test is essential for investigating the root genetic cause of infertility, recurrent pregnancy loss, or to identify specific genetic syndromes. This is not a routine test; it is a powerful, in-depth analysis that provides fundamental, lifelong answers for you and your family.
