Understanding Your Results
Normal
No chromosomal abnormalities or significant genetic variants detected.
Abnormal - Aneuploidy
Presence of extra or missing chromosomes, e.g., Trisomy 21 (Down syndrome).
Abnormal - Structural Change
Deletions, duplications, or translocations in chromosomes.
Abnormal - CNV
Copy number variations that may be pathogenic, requiring genetic counseling.
Consult a genetic counselor or healthcare provider if results are abnormal, for family planning, or if symptoms persist despite normal results.
Limitations
- ⚠May not detect all genetic variants, such as point mutations
- ⚠Requires expert interpretation by geneticists
- ⚠False positives or negatives possible in rare cases
- ⚠Limited to chromosomal and copy number changes; not for single-gene disorders
Risks & Considerations
- ●Minor bruising or pain at the blood draw site
- ●Rare risk of infection
- ●No significant risks for the fetus in prenatal testing when performed by experts
Interfering Factors
- ●Sample contamination
- ●Improper sample storage or transport
- ●Hemolyzed or clotted blood samples
- ●Recent blood transfusions may affect results
