The tests that confirm the pregnancy of twins or twins are medical analytics, which take into account the symptoms of pregnancy. However, only medical analysis and tests can confirm whether the pregnant woman is expecting two or more babies. So even if your pregnancy symptoms are exaggerated, as it corresponds to all multiple pregnancies, it is essential to visit the gynecologist so that through a series of tests he can confirm if you are expecting twins, triplets or more babies.
Gynecologists and obstetricians can detect a multiple pregnancy, whether it is twins, twins, triplets or more by performing the following tests on the pregnant woman:
1. Ultrasound. Ultrasound or sonography is generally the first test that can confirm a twin, triplet or more pregnancy. It enables babies to be seen in the womb using high-frequency sound waves. 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 baby's body, measure the growth of the babies in relation to the time of gestation 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. The beating of hearts. The gynecologist will be able to listen to the beating of the babies' hearts with a stethoscope at routine prenatal checkups.
3. Chorionic gonadotropin hormone analysis. It allows to quantify in the urine the amount of hCG (chorionic gonadotropin hormone) that the pregnant woman's body produces. This hormone is produced only during pregnancy and its presence is used to confirm pregnancy through a urine test. It is the same procedure that the 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 by the time of gestation, 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 gestational age, they can indicate a multiple pregnancy.
5. Amniocentesis. It is recommended only for women who have high-risk pregnancies, such as a multiple pregnancy. Amniocentesis is a test of your amniotic fluid that helps diagnose or rule out birth defects. It is not a routine test. Amniocentesis has the ability to reveal DNA-related details such as Down syndrome.
