Different Types of Tests Done in the First Trimester of Pregnancy
The first trimester tests during pregnancy. There are many physical and emotional changes that happen during this time. Doctors use various tests during these early months to learn about the relationship between the mother and the growing baby. This article explains the different tests done in the first trimester, starting from the basic blood test to more detailed genetic screenings. It helps navigate through the medical terms and understand these tests better.
Primary Tests:
Blood Test:
The first step in checking on a baby before birth is a blood test. This test looks at the mother’s blood to find important information like hormone levels and markers. These markers can give hints about possible problems. When combined with the mother’s age and other things, they help doctors assess the risks and decide what to do next.
Ultrasound Examination:
In the first trimester of pregnancy, an ultrasound employs sound waves to create images of the developing baby’s body and heartbeat. This tool helps doctors monitor growth, well-being, and overall progress.
Secondary Tests:
Prenatal Screening:
When a woman is pregnant, doctors check for genetic issues. They look at the baby’s DNA in the mother’s blood. This helps parents make choices.
Chorionic Villus Sampling (CVS):
To understand genes, doctors might take a small bit from the placenta using a tiny needle. This helps parents decide what to do based on genetic information.
Amniocentesis:
A special test checks the fluid around the baby in the womb. A small needle takes some fluid to look at the baby’s genes. Parents learn about possible problems and decide what to do.
Quad Test:
- Alpha-fetoprotein (AFP): A protein from the growing fetus' liver.
- Human Chorionic Gonadotropin (hCG) is a hormone that is synthesized by the placenta.
- Unconjugated Estriol (UE3): A hormone from baby's liver and placenta.
- Inhibin-A: A hormone formed by the placenta.
Reasons to Perform the First Trimester Screening During Pregnancy
During the first trimester of pregnancy, which spans the initial three months, there are opportunities for making informed decisions and engaging in thoughtful considerations. These early 1st trimester screenings extend beyond mere medical examinations; they also contribute to parents’ sense of being well-informed. By identifying potential challenges and positive aspects, these screenings enable parents to prepare and anticipate the journey ahead. This comprehension establishes a robust foundation for the pregnancy journey.
What To Expect From a First Trimester Screening Procedure?
The doctor will review the reports with the patient, analyzing ultrasound and blood test results alongside the mother’s age. They’ll determine the pregnancy’s safety and assess risks of chromosomal abnormalities (e.g., Edwards or Down’s Syndrome). A family history of genetic disorders increases the baby’s risk.
If the reports have not detected any abnormality, the unborn baby and its mother are fit and healthy. On the other hand, if the report shows any signs of abnormality, the doctor will recommend the expecting woman to opt for a non-invasive prenatal test, CVS or amniocentesis. These secondary tests will give more clarity to the scenario.
