Carrier sequencing and couple karyotype are genetic tests that may be considered before pregnancy or early in fertility care. They help identify risks that may affect conception, miscarriage, or the baby’s health.
These tests are especially useful for couples with recurrent pregnancy loss, infertility, a previous child with a genetic condition, close-relative marriage, or family history of inherited disorders.
What is carrier sequencing?
Carrier sequencing checks whether a person carries gene changes that could be passed to a child. Many carriers are completely healthy. A risk becomes important when both partners carry changes in the same recessive condition or when a condition follows another inheritance pattern.
What is couple karyotype?
A couple karyotype studies the chromosomes of both partners. It can detect balanced translocations, inversions, or other chromosomal rearrangements that may increase the chance of miscarriage or chromosomal imbalance in a pregnancy.
Who should consider these tests?
Testing may be advised after repeated miscarriages, failed IVF cycles, unexplained infertility, known family history, previous abnormal fetal genetic result, or belonging to a community with higher carrier frequency for certain conditions.
How can results guide care?
Results may help couples consider IVF with embryo testing, early prenatal diagnosis through CVS or amniocentesis, targeted testing for a known condition, or counselling about recurrence risk.
Does a normal result remove all risk?
No genetic test removes all risk. A normal result reduces specific known risks based on what was tested. Pregnancy scans, screening, and routine care remain important.
Genetic awareness is not about fear. It is about planning with better information, especially when there is a known family history or repeated pregnancy loss.
