Amniocentesis
- Typically performed around 15 weeks of pregnancy.
- Primarily used for confirming genetic disorders and detecting some birth defects.
Comparisons
- CVS does not identify certain birth defects like spina bifida or conditions such as rH incompatibility.
- In cases where early results are crucial, CVS may be the preferred option over amniocentesis.
