Lapsivesinäyte

Lapsivesinäyte, also known as amniotic fluid sample, is a medical procedure used to obtain a sample of the amniotic fluid that surrounds a fetus during pregnancy. This fluid contains fetal cells and other substances that can be analyzed for various diagnostic purposes. The procedure is typically performed between the 15th and 20th week of pregnancy, although it can be done earlier or later depending on the medical indication.

The primary reasons for performing a lapsivesinäyte include genetic testing, diagnosis of fetal infections, and assessment of fetal lung maturity. Genetic testing can detect chromosomal abnormalities such as Down syndrome, as well as inherited metabolic disorders. Fetal infections, such as cytomegalovirus or toxoplasmosis, can also be identified through analysis of the amniotic fluid. In later pregnancy, the fluid can be tested to determine if the fetus's lungs are mature enough for delivery, particularly in cases of premature labor.

The procedure itself involves inserting a thin needle through the mother's abdominal wall and uterine wall into the amniotic sac to withdraw a small amount of fluid. While generally safe, there are potential risks associated with lapsivesinäyte, including miscarriage, infection, and leakage of amniotic fluid. These risks are relatively low, and the decision to undergo the procedure is made after careful consideration of the benefits and risks in consultation with a healthcare provider. The results of the analysis typically take several weeks to become available.
