Q.Amniocentesis, a foetal-fluid based technique, was originally developed as a diagnostic test to detect:

Amniocentesis analyses foetal cells/chromosomes from amniotic fluid and can reveal the sex of the foetus; its misuse for sex determination is legally banned in India.

Amniocentesis is a prenatal diagnostic test in which a sample of amniotic fluid (containing foetal cells) is withdrawn to detect chromosomal abnormalities and metabolic disorders. Because a karyotype from these cells also reveals the foetus's sex (XX vs XY), the test has been misused for sex determination, which is why sex-determination using it is statutorily banned to prevent female foeticide.

Amniocentesis analyses fetal cells from amniotic fluid to detect chromosomal disorders such as Down syndrome.

Amniocentesis is a prenatal diagnostic technique in which a small sample of amniotic fluid (containing shed fetal cells) is withdrawn from the amniotic sac. The fetal cells are cultured and their chromosomes are examined (karyotyping) to detect chromosomal abnormalities, most notably Down syndrome (Trisomy 21), as well as other aneuploidies such as Klinefelter's and Turner's syndrome.

Amniocentesis is a prenatal diagnostic test based on foetal cells in the amniotic fluid, used to detect chromosomal/genetic disorders.

Amniocentesis is a foetal diagnostic technique based on the analysis of the amniotic fluid surrounding the developing foetus, which contains foetal cells shed from the foetus. Chromosomal analysis of these cells can reveal numerical or structural chromosomal abnormalities (e.g., Down's syndrome, Klinefelter's syndrome), as well as certain metabolic/genetic disorders. In India, its use purely for sex determination is legally banned (Pre-Natal Diagnostic Techniques Act) because of misuse leading to female foeticide; its legitimate medical use …
