Second trimester screening test

Pregnancy is one of the most sensitive periods of every woman's life.... So doing essential pregnancy tests should always be a priority.... Pregnancy tests are different based on pregnancy month.... Therefore, the second trimester test will be different from first trimester and first trimester..

If you too Want to learn about how to take a second trimester pregnancy test, stay with us in this article from GCORP LLC... as we are going to do an overview of the second trimester pregnancy test.

Second trimester screening tests

Maternal serum alpha-phytoprotein (MSAFP) and screening with multiple markers

This test is an optional genetic screening, so as with all screening tests, you can discuss the pros and cons with your doctor.

The MSAFP test measures the level of alpha-phytoprotein, which is one of the proteins produced by the body of the fetus. Abnormal levels of this protein indicate the possibility of Down syndrome or neural tube defects such as spina bifida.

After the initial diagnosis, these two abnormalities can be proven using ultrasound or amniocentesis... The blood sample prepared for the MSAFP test is also evaluated for hCG and estriol hormone levels, which is also called the triple test.

The quadruple test significantly increases the probability of diagnosing Down's syndrome... This test detects 75% of neural tube defects and 75-90% of Down's syndrome (depending on the mother's age). Of course, there is also the possibility of a false positive result... In about 3-5% of women whose test results are abnormal, the child does not have a genetic problem.

Non-invasive prenatal screening (NIPT)

This test, which is performed using free DNA, can be performed in the 10th week of pregnancy. In this test, the relative amount of free fetal DNA in the mother's blood is measured.

It is believed that this test can detect 99% of Down syndrome cases during pregnancy.... This test also checks for some other chromosomal abnormalities.

sonography

Ultrasound is usually recommended at the 20th week of pregnancy, but it may be done at any other time of pregnancy.. Ultrasound may be used for various reasons, including diagnosing multiples, determining the date of delivery, checking for problems such as placenta previa and placenta, such as abdominal descent and slow placental development..

In some cases, if genetic abnormalities are suspected, the mother for Genetic tests are mostly referred to a medical geneticist. In ultrasound, a device called a probe that produces sound waves is moved on the abdomen to create an image of the fetus on a computer screen.

Currently, 3D ultrasounds provide a clearer picture of the fetus, but they are not available everywhere. However, it is not clear whether these ultrasounds have any particular advantage over 2D ultrasound in terms of helping with a healthy pregnancy and delivery.

Glucose Screening

This test is usually done at week 24 to 28 of pregnancy... This test is usually done to identify gestational diabetes, which can cause the baby to be enlarged (macrosoma), difficult delivery, and a series of problems for the mother and fetus.

This test measures the blood sugar level one hour after consuming a glass of special syrup.... If the blood sugar is high, a glucose tolerance test with higher sensitivity is performed in which the person receives a glucose solution and his blood sample is evaluated every 2 to 3 hours.

Amniocentesis

This optional test is usually performed at 15 to 18 weeks of pregnancy and in women over 35 years of age, women with a higher risk of genetic disorders in the fetus, or women whose MSAFP test, multiple markers, or free DNA testing was suspicious.

In this test, a needle is inserted through the abdomen into the amniotic sac and some fluid containing fetal cells is removed.. Analysis of this test can identify neural tube defects and genetic disorders. It detects 100% of the specific genetic abnormality.

Fetal Doppler ultrasound

Doppler ultrasound uses sound waves to check blood flow in the veins. Fetal Doppler can determine whether the blood flow of the placenta or fetus is normal.

Photoscopy

Photoscopy allows the doctor to observe the fetus using a thin and flexible instrument called a photoscope. Fetoscopy can detect some diseases and defects that are not detected by other tests, such as amniocentesis, ultrasound, and chorionic villus sampling. Abnormality of the fetus is more than usual.

If you are also pregnant, it is better to take pregnancy tests seriously... To find out about the second trimester pregnancy test, it is better to visit the best gynecologist...
