What Is a Pregnancy-Associated Plasma Protein A (PAPP-A) Test?
The PAPP-A test measures the level of Pregnancy-Associated Plasma Protein A, a protein produced by the placenta during early pregnancy. Doctors order this test as part of the first-trimester prenatal screening to check a baby's risk of certain chromosomal conditions. A blood sample is drawn from a vein in the arm and analysed in the laboratory. It is also known as the Pregnancy-Associated Plasma Protein A test or, when combined with a free beta-hCG measurement, the Double Marker PAPP-A test.
What Does a Pregnancy-Associated Plasma Protein A (PAPP-A) Test Measure?
This PAPP-A blood test looks at one or two specific markers found in the mother's bloodstream during early pregnancy. The table below describes what each marker represents.
| Parameter | What It Measures |
|---|---|
| PAPP-A | A protein made by the growing placenta; plays a role in foetal growth regulation. Levels normally rise steadily throughout pregnancy. |
| Free beta-hCG (when part of Double Marker) | A hormone produced by the placenta in large quantities during early pregnancy; levels typically peak around 8 to 10 weeks, then stabilise. |
Why Is a Pregnancy-Associated Plasma Protein A (PAPP-A) Test Done?
The first trimester PAPP-A test is a routine screening tool, not a symptom-driven one. It is offered to pregnant women to assess statistical risk, not to diagnose a condition outright.
Common Symptoms That May Require This Test
Because this is a scheduled screening test, it is not triggered by symptoms. The following situations typically lead a doctor to recommend it:
- Pregnancy confirmed at 10 to 14 weeks of gestation
- Maternal age above 35 years
- Previous pregnancy affected by a chromosomal condition
- Family history of chromosomal abnormalities
- Abnormal findings on an early ultrasound scan
- Conception through IVF or assisted reproductive techniques
Conditions This Test Can Help Detect
The prenatal screening PAPP-A test helps assess the risk for several conditions. These include:
- Down syndrome (Trisomy 21)
- Edwards syndrome (Trisomy 18)
- Patau syndrome (Trisomy 13) and sex chromosome abnormalities
- Pre-eclampsia (a blood pressure complication in pregnancy)
- Foetal growth restriction and preterm delivery risk
- Gestational diabetes
Pregnancy-Associated Plasma Protein A (PAPP-A) Test During Pregnancy
The first-trimester PAPP-A test is a standard part of prenatal care recommended for all pregnant women, typically performed between weeks 11 and 14. It provides early information about the baby's risk of chromosomal conditions such as Down syndrome and Trisomy 18. In most countries, biochemical screening using PAPP-A and free beta-hCG is offered as part of every pregnancy care programme.
How to Prepare and What to Expect
Preparation for this test is straightforward, and the procedure itself is quick and simple.
Do You Need to Fast?
No fasting is required. You can eat and drink as normal before your appointment. The only important step is to share your exact pregnancy week, weight, smoking status, and method of conception with your doctor or laboratory, as these details affect how results are calculated.
Practical Tips Before Your Test
A few simple steps will help ensure your results are as accurate as possible:
- Eat and drink normally on the day of the test
- Inform the lab of your exact gestational age (in weeks and days)
- Share details of any medications you are currently taking
- Let the lab know your conception method (natural or IVF)
- Disclose your smoking status and pre-existing conditions such as diabetes
- If an NT (nuchal translucency) ultrasound is also scheduled, try to have both done on the same day
Step-by-Step Procedure
The blood collection process is quick and causes minimal discomfort. Here is what to expect:
- A trained phlebotomist will tie a soft band around your upper arm to make your vein easier to locate.
- The skin is cleaned with an antiseptic wipe.
- A fine needle is gently inserted into the vein, usually on the inner side of the elbow.
- A small amount of blood (around 1 to 2 ml) is collected into a tube.
- Once the collection is complete, the needle is removed, and you will be asked to press a cotton ball over the site for a moment to stop any minor bleeding.
- The sample is labelled and sent to the laboratory for analysis.
Factors That Can Affect Accuracy
Several factors can influence your PAPP-A reading and are taken into account when your results are calculated:
- Gestational age at the time of the test
- Maternal body weight (higher weight can lower readings)
- Ethnic background (levels naturally differ across ethnicities)
- Smoking (lowers PAPP-A concentrations)
- IVF conception (associated with lower first-trimester levels)
- Multiple pregnancies (twins or triplets alter hormone levels)
- Pre-existing diabetes (Type 1 or Type 2)
Understanding Your Pregnancy-Associated Plasma Protein A (PAPP-A) Test Results
Results from the aneuploidy screening PAPP-A test are expressed as MoM (Multiples of the Median), which compares your level to the expected average for your gestational age. Your doctor will review these values alongside your ultrasound findings and other clinical details.
| Parameter | Low | Normal | High |
|---|---|---|---|
| PAPP-A | Below 0.5 MoM | 0.5 to 2.0 MoM | Above 2.0 MoM |
"These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice."
Results During Special Conditions
Certain personal circumstances can shift your PAPP-A reading even in a normal pregnancy. Your lab and doctor adjust for these when interpreting your report:
- Smokers tend to have lower PAPP-A concentrations, which may affect risk calculations.
- Women who conceived through IVF typically show lower first-trimester PAPP-A levels.
- Pre-existing Type 1 or Type 2 diabetes is associated with reduced PAPP-A concentrations.
- A high maternal BMI (body mass index) can be associated with lower PAPP-A levels.
- Twin or triplet pregnancies alter hormone levels and require separate reference ranges.
How to Maintain Healthy Levels
While PAPP-A levels are largely determined by placental function, these general pregnancy wellness habits support overall health:
- Attend all scheduled prenatal check-ups and follow your doctor's guidance throughout pregnancy.
- Eat a balanced diet and maintain a healthy pregnancy weight.
- Avoid smoking and alcohol entirely during pregnancy.

Frequently Asked Questions
The PAPP-A test measures a protein produced by your developing placenta. It is typically done between 11 and 14 weeks of pregnancy as part of first-trimester screening. The test helps assess the statistical risk of chromosomal conditions in your baby.
No. A low result only signals a higher statistical risk, not a confirmed diagnosis. Your doctor will recommend further tests, such as NIPT or diagnostic procedures, to get a clearer picture. Many women with low PAPP-A go on to have healthy pregnancies.
Yes, the PAPP-A blood test is very safe. It involves a standard blood draw from a vein in your arm. You may feel a brief pinch when the needle is inserted, but significant side effects are rare.
No fasting is needed. You can eat and drink as usual before the test. Just remember to share your exact gestational age and relevant health details with the laboratory.
Several factors can influence readings, including body weight, smoking, IVF conception, multiple pregnancies, pre-existing diabetes, and ethnic background. The laboratory accounts for most of these when calculating your result.
Results for the PAPP-A serum test are typically available within 2 to 5 days. Your report will include an interpretive summary, and your doctor will discuss the findings with you.
A high-risk screening result does not confirm a problem. Your doctor will discuss next steps, which may include additional testing such as Non-Invasive Prenatal Testing (NIPT) or procedures like chorionic villus sampling (CVS) or amniocentesis. These further tests provide more definitive information.
