Patient's question:
What are chromosomes, and what does it mean when a couple has incompatible chromosomes?Doctor's answer:
Chromosome testing for adverse pregnancy history: This refers to conditions such as miscarriage, stillbirth, or the birth of malformed children. Individuals with an adverse pregnancy history generally appear normal, as their chromosomal abnormalities are typically inversions or balanced translocations without the loss of genetic material. Approximately 1-1.5% of cases are caused by chromosomal abnormalities, making it necessary for this group to undergo chromosome testing. There is no such thing as "chromosomal disharmony"; rather, it is that there should be chromosomal abnormalities present, requiring chromosome testing.
