Area of Science:

  • Prenatal Diagnosis
  • Human Genetics
  • Reproductive Biology

Background:

  • Fetal karyotyping is crucial for diagnosing chromosomal abnormalities.
  • Techniques include chorionic villus sampling, amniocentesis, and fetal blood sampling.
  • Interpreting results can be challenging due to confined placental mosaicism or other tissue-specific variations.
