Tests that confirm the pregnancy of twins

Tests that confirm the pregnancy of twins or twins are medical tests, which take into account the symptoms of pregnancy. However, only medical tests and tests can confirm if the pregnant woman is expecting two or more babies. So even if your pregnancy symptoms are exaggerated, as befits all multiple pregnancies, it is essential to visit the gynecologist so that through a series of tests confirm whether you are expecting twins, triplets or more babies.

Medical tests to confirm the pregnancy of twins or twins

Gynecologists and obstetricians can detect a multiple pregnancy, whether twins, twins, triplets or more by performing the following tests on the pregnant woman:

1. Ultrasound. Ultrasound or ultrasound is usually the first test that can confirm a twin pregnancy, triplets or more. It allows to visualize the babies inside the uterus by means of high frequency sound waves. The ultrasound is painless, they do not have any unwanted side effects for both mother and baby and through this technique the sonographer can measure and identify the organs of the babies' body, measure the growth of the babies in relation to the gestation time and assess the well-being of babies. The rest of the tests will confirm the presence of a multiple pregnancy, but only the ultrasound can show what number of babies we are talking about.

2. Heartbeat. The gynecologist can listen to the heartbeat of babies with a stethoscope in routine prenatal check-ups.

3. Analyzes of the chorionic gonadotrophin hormone. It allows the amount of hCG (chorionic gonadotrophin hormone) produced by the body of the pregnant woman to be quantified in the urine. This hormone is produced only during pregnancy and its presence serves to confirm pregnancy through a urine test. It is the same procedure that pregnancy tests follow. The amount of chorionic gonadotropin increases by at least 60 percent per day in the first weeks of pregnancy. When the analyzes reveal that the amounts of hCG are higher than those that would correspond to the time of pregnancy, they can indicate a multiple pregnancy.

4. Triple screening test. It is usually done between weeks 15 and 18 of pregnancy. Triple screening measures three substances: hCG, unconjugated estriol and alpha-fetoprotein. When the levels present high amounts of the three substances in relation to the gestational age they can indicate a multiple pregnancy.

5. Amniocentesis.It is recommended only for women who have high-risk pregnancies, such as multiple pregnancy. Amniocentesis is an analysis of your amniotic fluid that helps diagnose or rule out congenital defects. It is not a routine test. Amniocentesis has the ability to reveal details related to DNA such as Down syndrome.
