In surrogacy pregnancy one of the major questions from intended parents is related to genetic disorder of the fetus. Private doctor may give a recommendation to surrogates of amniocentesis performance in case of abnormal triple marker test result.
Amniocentesis is a prenatal test, which make available information about fetus genetic condition from the sample of pregnant woman amniotic fluid. An amniotic fluid is a substance and fetus is surrounded with it. It includes cells shed by the fetus. Amniocentesis identifies chromosome abnormalities, genetic disorders and neural tube defects. Down syndrome, same as trisomy 21 is the most common chromosome abnormality. Also another genetic disorder which can be examined is cystic fibrosis and spina bifida.
Amniocentesis risks and side effects
Although amniocentesis is considered to be a safe procedure, it is known as an invasive diagnostic test that does pose possible risks. One of the major risks related to amniocentesis test is miscarriage. Statistically the risk of miscarriage in case of amniocentesis is 0.5- 1 %
There might be few reasons why miscarriage may happen: water braking, infection in the uterus and labor being induced prematurely. Quite seldom but still needle may come in contact with the fetus, therefore the procedure is performed carefully by using a sonogram. After the procedure surrogate may have a feeling of cramping, fluid leaking and irritation on the puncture area.
When amniocentesis is needed to be performed
During the pregnancy of surrogate mother triple marker test is being performed at pregnancy week 16-17. If any of the results of this test BHCG , AFP or Free Estriol is out of the norms then surrogates address to the genetic. Genetic has to write a counseling and give the solid explanation why amniocentesis procedure is recommended. Then surrogates visit to a quite well known specialist in one of the best clinic and the procedure is conducted there
Amniocentesis is usually done when surrogate mother is in pregnancy week 16 -21. The needle should enter in the amniotic sac and it is crucial to find the safe location for the needle. Therefore during this procedure ultrasound scan is performed as a guide to find harmless location and safely remove sample of the fluid. Overall the procedure takes around 30 minutes. This procedure is described as uncomfortable rather than painful. The sample of the amniotic fluid is sent to Limback laboratory and through this lab the fluid is sent to Germany for further examination. Results may take 3-4 weeks to be returned to the laboratory.
In New Life Georgia`s history there was not a single case of miscarriage because of this procedure. To summarize the topic amniocentesis test has a high levels of accuracy (98-99%). Though this analyses does not measure the severity of the birth defects.
