What Does a Maternal Screen (Triple Test) Second Trimester Test Measure?
This test measures three key markers in your blood:
- AFP: Evaluates risk of open neural tube defects and certain abdominal wall defects
- Beta HCG: Helps assess risk of chromosomal conditions such as Down syndrome
- uE3: Assists in evaluating fetal well being and chromosomal risk
Using your age, gestational age, ultrasound findings, and hormone levels, a risk factor is calculated for:
- Trisomy 21 also known as Down syndrome
- Trisomy 18 also known as Edward syndrome
- Open neural tube defects
Maternal Screen (Triple Test) Second Trimester Test: Who Needs It and Why It’s Done
What Symptoms May Call for a Maternal Screen (Triple Test) Second Trimester Test?

- You are above 35 years of age
- There is a family history of chromosomal disorders
- Previous pregnancy had genetic abnormalities
- Ultrasound findings suggest increased risk
- You have diabetes or other high risk conditions
Who Should Get a Maternal Screen (Triple Test) Second Trimester Test?
You may be advised to take this test if you are:
- Pregnant between 14 and 22.6 weeks
- Seeking second trimester prenatal screening
- At increased maternal age risk
- Having abnormal first trimester screening results
- Carrying risk factors identified on ultrasound
Why is a Maternal Screen (Triple Test) Second Trimester Test Done?
It is done to estimate the statistical risk of certain fetal abnormalities. The results help guide decisions about further diagnostic tests such as detailed ultrasound or invasive procedures when necessary.
Importance of Maternal Screen (Triple Test) Second Trimester Test
This screening test plays an important role in prenatal care. It helps identify pregnancies that may have a higher risk of chromosomal abnormalities or neural tube defects. Early identification allows timely counselling, detailed imaging, and further diagnostic testing if required.
The risk calculation is performed using validated software that adjusts results based on maternal age and hormone values converted into MoM values.
