Understanding Your Results
No numerical or structural chromosomal abnormality detected in the amniotic fluid cells.
May indicate conditions such as trisomies or monosomies and requires genetic counselling.
Requires further evaluation and referral to a clinical geneticist for detailed counselling.
Consult a doctor or clinical geneticist if the karyotype report is abnormal, if there is a history of chromosomal abnormality in a previous pregnancy, or if fetal abnormalities are detected on ultrasound.
