Understanding the tests you’ll need during pregnancy is a critical part of prenatal care. These tests help monitor both maternal health and fetal development from the earliest weeks through delivery. While the number of appointments and screenings may feel extensive, each test is carefully selected to provide valuable clinical insight.
These evaluations allow your provider to identify potential concerns early, manage risks appropriately and support the healthiest possible outcome for you and your baby.
Your specific testing schedule will depend on your medical history, age, family history and any preexisting conditions. Understanding the purpose behind these screenings can make the process feel more manageable and reassuring.
Tests You’ll Need During the First Trimester: Establishing a Baseline
The first trimester focuses on confirming the pregnancy and establishing a health baseline. common tests you’ll need during pregnancy during this stage include:
- Comprehensive blood work: Determines blood type, Rh factor, screens for anemia and checks for infections such as HIV, hepatitis B and syphilis.
- Urinalysis: Screens for infection, kidney function abnormalities and elevated protein or glucose levels.
- Early ultrasound: Confirms viability, establishes accurate gestational dating and evaluates early fetal development.
- Optional genetic screening: Noninvasive blood tests may assess the risk of chromosomal conditions.
In some cases, thyroid function testing or additional hormone evaluations may be recommended, particularly if you have a history of endocrine disorders or pregnancy loss.
These early tests you’ll need during pregnancy provide essential information that guides the remainder of your prenatal care plan and helps identify patients who may benefit from closer monitoring.
Tests You’ll Need During the Second Trimester: Detailed Evaluation and Screening
During the second trimester, attention shifts toward monitoring fetal growth and identifying structural concerns. The anatomy ultrasound, typically performed between 18 and 22 weeks, provides a comprehensive assessment of fetal organs, placental placement and amniotic fluid levels.
This imaging study also evaluates cervical length in certain patients who may be at risk for preterm birth.
Additional tests you’ll need during pregnancy often include maternal serum screening and glucose testing between 24 and 28 weeks to evaluate for gestational diabetes.
Early detection of elevated blood sugar allows for dietary modifications or medical management to reduce the risk of complications such as excessive fetal growth, preeclampsia or delivery complications.
If indicated, additional ultrasounds may be recommended to monitor growth trends or placental position.
Tests You’ll Need During the Third Trimester: Monitoring and Delivery Preparation
In the third trimester, testing is directed toward ensuring stability as delivery approaches. A Group B streptococcus screening is routinely performed between 35 and 37 weeks. If positive, antibiotics during labor significantly reduce newborn infection risk.
Your provider may repeat blood work to reassess anemia, platelet levels and overall maternal health. Blood pressure monitoring becomes especially important to screen for preeclampsia.
In higher risk pregnancies, fetal monitoring such as nonstress testing or biophysical profiles may be ordered to evaluate fetal well-being, placental function and amniotic fluid levels.
At this stage, tests you’ll need during pregnancy help determine readiness for labor and assist in planning a safe delivery strategy.

Not every patient requires the same number or type of tests. High risk pregnancies, multiple gestations or preexisting medical conditions may require additional imaging, specialist consultation or more frequent prenatal visits.
