During pregnancy, a range of tests and screenings are recommended to ensure optimum prenatal care and development, as well as the well-being of the mother. Some of these tests are routine like , hemoglobin , sugar , thyroid etc. However, there are some special USG and Blood-based tests recommended at different stages of pregnancy . Here are some of the common tests during pregnancy:
It helps diagnose genetic disorders before birth, like cystic fibrosis, thalassemia, sickle cell disease and many more. The screening methods usually involve blood tests of Father and Mother.
First trimester screening
This is done between 11 and 14 weeks of pregnancy to determine the risks of the fetus of having Downs syndrome and related conditions. It includes ultrasound scans for fetal neck skin thickness ( NT ) and nasal bone determination. Also, added with this a maternal blood test called double Marker to assess the probability of those conditions.
Second trimester prenatal screening
Principally similar to First Trimester Screening. Done between 15 and 20 weeks of pregnancy who presents late. it includes a blood test called Quadruple Marker, apart from blood Test.
There are two types of ultrasounds: Abdominal Ultrasound and Transvaginal Ultrasound. Following, there exist different types of ultrasound imaging techniques: 2D, 3D, and 4D. The 4D ultrasound is a modern technique that visualizes the unborn baby move in real time. Ultrasounds may be done at different phases (trimesters) of pregnancy to identify the location and estimate the due date (Early Pregnancy TVS ), to identify structural abnormalities in the baby ( anomaly Scan), measure fetal growth , water around baby and blood flow to it ( Fetal well being and Doppler study )
In addition, depending on individual cases, the doctor might recommend more tests. Like, amniocentesis / chorionic villus sampling ( CVS ) helps diagnose chromosomal or genetic disorders, and fetal echocardiography to specially check the fetal heart.
