Medical tests before and during pregnancy:
Introduction:
Before deciding to get pregnant one should be aware of her medical and fitness position. Few medical tests before and during pregnancy play a pivotal role in providing valuable insights into the pregnancy process. Such tests will help in identifying potential risks and promoting a smooth and healthy gestation. In this blog, we will explore the significance of essential medical tests before and during pregnancy, shedding light on the different screenings and examinations that contribute to a safe and successful pregnancy. Let’s go through each test one by one.
Preconception Health Screening:
-
Preconception Genetic Testing:
Before conception, certain genetic tests can help to diagnose some hereditary disorders that passes from parents to offspring. These tests provide valuable information about the carrier status of potential genetic disorders. On the basis of such information, important decisions are made about family planning. Some common preconception tests(medical tests before pregnancy) include:
General Health Screenings:
Complete Blood Count (CBC): To check for anemia or other blood disorders.
Measurement of Blood Pressure: Blood pressure can complicate pregnancy.
Thyroid Function Tests: To ensure thyroid health (TSH, T3, T4), as thyroid imbalances can impact fertility and pregnancy.
Blood Glucose Tests: To screen for diabetes or prediabetes. Diabetes which can complicate pregnancy.
Vaccines and Immunizations:
Rubella Test: Rubella (German measles) can cause birth defects, so if you’re not immune, you may need to get vaccinated before pregnancy.
Varicella (Chickenpox) Immunity Test: Similar to rubella, chickenpox can be dangerous during pregnancy.
Flu Vaccine: The flu vaccine is advised by doctors for all women trying to conceive and during pregnancy.
Tdap (Tetanus, Diphtheria, and Pertussis): Vaccination is recommended before pregnancy or early in pregnancy to protect both the mother and baby from pertussis.
2. Pre-Pregnancy Checkup:
This checkup is essential for prospective mother. This may include screenings for chronic conditions, such as diabetes and hypertension, ensuring that any pre-existing health issues, such as Toxoplasmosis, T.B, etc. are managed effectively before conception. Some medical tests before pregnancy include:
Genetic Screening:
Carrier Screening: Genetic testing for common inherited conditions like sickle cell anemia ,cystic fibrosis, , or Tay-Sachs disease.
Cystic Fibrosis (CF) Carrier Screening: Identifies carriers of CF, a genetic disorder that can affect the lungs and digestive system. Infectious Disease Screenings:
HIV Test: HIV testing is recommended to ensure early treatment if necessary.
HB’sAg HCV Testing: Hepatitis B &C infections can affect pregnancy and be transmitted to the baby.
Syphilis and Chlamydia Testing: Sexually transmitted infections may complicate pregnancy and affect the baby.
Fertility Assessment:
Ovarian Reserve Testing: This includes tests such as an ultrasound to count antral follicles or blood tests for hormones like AMH (anti-Müllerian hormone) to assess a woman’s fertility potential.
Early Pregnancy Tests:
- Confirmation of Pregnancy:
The journey begins with a simple pregnancy test. The test detect the presence of hCG(human chorionic gonadotropin) in the urine. A positive result prompts a visit to the healthcare provider for further confirmation and initiation of prenatal care.
- Blood Tests:
Early blood tests can assess the levels of important hormones, such as progesterone and estrogen, providing insights into the health of the pregnancy. These medical tests can also identify potential issues like anemia or Rh incompatibility.
Complete Blood Count (CBC): To check for infections, anemia, or other conditions.
Blood Type and Rh Factor: To determine if the mother has a compatible blood type and whether the baby may be at risk for Rh incompatibility.
Glucose Screening (Gestational Diabetes Test): The test is done during 24-28 weeks to check for gestational diabetes during pregnancy.
Urine Culture and Protein Screening: To detect urinary tract infections and signs of preeclampsia or kidney problems.
HIV and Syphilis Testing: These tests are repeated during pregnancy to ensure no new infections.

First Trimester Screenings:
- Nuchal Translucency (NT) Scan:
The NT scan is done to identify potential chromosomal abnormalities, including Down syndrome and to check the thickness of the back of the baby’s neck.
- First Trimester Blood Tests:
Combined with the NT scan, blood tests measuring certain markers help refine the risk assessment for chromosomal abnormalities.
Screening for Genetic Disorders:
Non-Invasive Prenatal Testing (NIPT): This test is done around 10 weeks to screen for genetic conditions like Down syndrome, Trisomy 18, and Trisomy 13.Chorionic Villus Sampling (CVS): A test done between 10-13 weeks to sample placental tissue for genetic testing. It’s more invasive and typically reserved for women at higher risk for genetic disorder
Second Trimester Screenings:
Some medical tests during the second trimester of pregnancy include:
- Maternal Serum Alpha-Fetoprotein (MSAFP) Test:
This test (MSAFP) is done between weeks 15 and 20.This test is done for neural tube defects and other chromosomal abnormalities.
Amniocentesis: A test typically done between 15-20 weeks to check for chromosomal abnormalities and neural tube defects by sampling the amniotic fluid
- Anatomy Ultrasound:
This detailed ultrasound is performed at around 18 to 22 weeks. The test will examine the baby’s organs and structures, ensuring proper development and identifying any potential issues.
Third Trimester Tests:
-
Glucose Screening Test:
Screening for gestational diabetes is conducted between 24 and 28 weeks, helping manage and treat this condition to prevent complications.
-
Group B Streptococcus (GBS) Screening:
A swab test is done to checks for the presence of GBS bacteria during 35 to 37 weeks. If any bacteria are found, special precautions are required during labor to protect the baby.
Cervical Length Measurement: occasionally performed to assess the risk of preterm birth.
Preeclampsia Screening (Blood Pressure and Urine Protein Tests): Blood pressure is checked regularly, and urine is tested for protein to detect early signs of preeclampsia.

Postpartum Tests and Follow-up
After reading medical tests before and during pregnancy, let’s examine post pregnancy tests. After the baby’s birth, some tests and follow-up care for both the mother and the baby are necessary to ensure their fitness.
For the Mother:
Postpartum Checkup (6-8 weeks after delivery): This includes a physical examination and mental health screening to check for signs of postpartum depression or anxiety.
Blood Pressure Check: This is done to ensure that any postpartum hypertension or preeclampsia complications are managed.
Glucose Testing (In case of presence of gestational diabetes): A follow-up test is necessary to check for diabetes after pregnancy.
Thyroid Function Tests: women with thyroid problems during pregnancy need to follow up to monitor thyroid function postpartum.
For the Baby:
Newborn Screening: A series of tests conducted in the first 48 hours after birth to check for metabolic, genetic, and endocrine disorders.
Hearing Screening: A routine test performed on newborns to check for hearing loss.
Jaundice Test: Newborns are screened for jaundice.
Breastfeeding Support and Mental Health Screening: Follow-up support to ensure the mother is able to breastfeed successfully.
The Final words:
Regular medical tests before, during, and after pregnancy help ensure that both the mother and baby are healthy and that potential issues are identified early for better outcomes. These tests can be performed only on the advice of your doctor. Always feel free to ask your doctor about any specific tests. for more in-depth articles ,click Azilife
