Understanding Your Results
Normal Karyotype
No chromosomal abnormalities detected.
Aneuploidy (e.g., Trisomy 21)
Presence of extra or missing chromosomes, associated with conditions like Down syndrome.
Structural Abnormality (e.g., Translocation)
Changes in chromosome structure, which may be balanced or unbalanced.
Mosaicism
Presence of two or more cell lines with different karyotypes.
Consult a healthcare provider if results indicate abnormalities, or if symptoms such as developmental delays, recurrent miscarriages, or infertility persist.
Limitations
- ⚠Cannot detect small genetic mutations
- ⚠Requires viable cells for culture
- ⚠Longer turnaround time compared to some molecular tests
Risks & Considerations
- ●Bruising at the collection site
- ●Infection (rare)
