What Is the Quadruple Test? A Complete Guide for Expecting Mothers
By Dr. Shivambika Joshi – Compassionate Women’s Health Specialist & the best Gynecologist in Ferozepur
Pregnancy is a beautiful journey filled with excitement, anticipation, and also plenty of questions. One of the most common concerns expecting mothers have is whether their baby is developing normally. Thanks to advances in prenatal screening, doctors today can detect certain risks early in pregnancy, helping parents make informed decisions.
One such important screening is the Quadruple Test, often recommended during the second trimester. At our clinic, Dr. Shivambika Joshi, known as the best Gynecologist in Ferozepur, ensures every expecting mother receives the right guidance, clarity, and reassurance throughout her pregnancy journey.
This blog explains what the Quadruple Test is, why it's done, how it works, and what results may mean—in simple, parent-friendly language.
What Is the Quadruple Test?
The Quadruple Test, also known as the Quad Screen, is a simple blood test done between 15 to 22 weeks of pregnancy, ideally around 16–18 weeks. The test measures four important substances in the mother’s blood:
- AFP (Alpha-Fetoprotein) – produced by the baby’s liver
- hCG (Human Chorionic Gonadotropin) – produced by the placenta
- Estriol (uE3) – a hormone made by the fetus and placenta
- Inhibin-A – produced by the placenta
Changes in the levels of these four markers help assess the risk of certain chromosomal and developmental conditions in the baby.
Dr. Shivambika Joshi, the best Gynecologist in Ferozepur, explains that the Quadruple Test is non-invasive, safe, and highly recommended, especially for women over 30, women with a family history of genetic disorders, or those who missed the first-trimester screening.
What Conditions Can the Quadruple Test Detect?
The Quadruple Test does not diagnose a condition; rather, it estimates the risk of the baby having certain conditions. These include:
1. Down Syndrome (Trisomy 21)
A genetic condition that causes developmental delays and unique facial features.
The Quad Test is especially useful in detecting increased risk.
2. Edwards Syndrome (Trisomy 18)
A rare but serious condition that affects growth and development.
3. Neural Tube Defects (NTDs)
Such as:
● Spina bifida
● Anencephaly
AFP levels primarily help identify these issues.
Expecting mothers often feel anxious about these conditions, which is why consulting the best Gynecologist in Ferozepur ensures proper interpretation of results and guidance on next steps.
How Is the Quadruple Test Done?
The process is simple and quick:
- A small blood sample is taken from the mother’s arm.
- The lab assesses levels of the four markers.
- The results are interpreted along with:
○ Mother's age
○ Weight
○ Race
○ Due date
○ Whether it's a single or twin pregnancy
Adjusting for these factors ensures an accurate risk calculation.
The results are usually available within a few days.
What Do the Quad Test Results Mean?
The results will categorize the risk as:
● Low risk, or
● High risk
A low-risk result is reassuring, but does not guarantee the absence of any condition.
A high-risk result does not confirm a disorder—only that additional testing may be beneficial.
If needed, Dr. Shivambika Joshi, the best Gynecologist in Ferozepur, may suggest additional tests such as:
● Level II ultrasound
● Non-Invasive Prenatal Testing (NIPT)
● Amniocentesis
These help provide further clarity and confirm the health status of the fetus.
Who Should Consider the Quadruple Test?
Although the test is optional, it is strongly recommended for:
● Pregnant women aged 35 or older
● Those who missed first-trimester screening
● Women with a family history of genetic conditions
● Women on certain medications
● Those with previous pregnancies affected by chromosomal abnormalities
The best Gynecologist in Ferozepur, Dr. Shivambika Joshi, ensures each patient understands whether the test is suitable for them.
