Understanding Your Results
Normal
No pathogenic chromosomal abnormalities detected.
Abnormal
Pathogenic copy number variations identified; consult a genetic counselor for implications.
Variant of Uncertain Significance (VUS)
Further testing and clinical correlation recommended.
Consult a doctor or genetic counselor if results are abnormal, if there is a family history of genetic disorders, or for guidance on management and family planning.
Limitations
- ⚠Cannot detect balanced chromosomal rearrangements
- ⚠May not identify point mutations or single gene disorders
- ⚠Limited for detecting low-level mosaicism
Risks & Considerations
- ●Minimal risks for blood draw (e.g., bruising)
- ●For amniocentesis or CVS: small risk of miscarriage or infection
- ●Emotional impact of results
Interfering Factors
- ●Contaminated or degraded sample
- ●Insufficient DNA quantity
- ●Maternal cell contamination in prenatal samples
