Question

Which is a common match for an Amniotic fluid test?
A. IVF
B. ZIF
C. GIFT
D. None of the above

Answer 1

The amniotic fluid test is most commonly known as Amniocentesis. It is a test to determine Foetal Sex. Amniocentesis is based on the chromosomal arrangement in the amniotic fluid neighbouring the developing embryo.

Complete answer:
The process of amniocentesis involves the excursion of amniotic fluid from the uterus for prenatal diagnosis. In the 14th and 15th week of pregnancy, amniotic fluid is taken out from the uterus of the mother with the help of a long surgical needle. This amniotic fluid contains a few cells of embryo-like skin, liver, placenta, etc. This test is conducted to determine any genetic disorder or chromosomal abnormalities like Down syndrome, metabolic disorders like deficiency of protein, Enzymes, hormones, etc. and also for the detection of Sex. Gamete Intra Fallopian Transfer (GIFT), Zygote IntraFallopian Transfer (ZIFT), and IVF are techniques used against Infertility in couples. These techniques are examples of assisted reproductive technologies (ART).

GIFT- It involves the transfer of an ovum which is collected from the ovary to the fallopian tube of either the same female or the females who cannot produce an ovum but can offer an appropriate environment for fertilization. The removed eggs are placed into the fallopian tube along with the male sperm for fertilization.
ZIFT- It involves zygote or early embryo transfer into the Fallopian tube of the same mother or the surrogate mother.
IVF- It is in vitro fertilization i.e. fertilization outside the body. A test-tube baby is a remarkable technique that is used today.

Therefore the correct option is (D) none of the above.

Note: Assisted reproductive technologies are of two types. Invitro fertilization where the fusion of gametes occurs within the female and Invivo fertilization i.e fertilization happens outside the body. GIFT is an example of Invivo fertilization whereas ZIFT is an example of Invitro fertilization.
