Alpha Fetoprotein (AFP) Test
The Alpha Fetoprotein (AFP) test measures a protein made by the fetal liver and, in adults, can signal liver disease, certain cancers, or pregnancy-related conditions. But one test alone rarely gives the full picture. Here is what you need to know if your doctor has recommended it in Bangladesh.
What Is the Alpha Fetoprotein (AFP) Test?
Alpha fetoprotein is a protein normally produced by the fetal liver and yolk sac during pregnancy. In healthy adults, AFP levels are very low (usually below 10–15 ng/mL). When certain cells become abnormal — as in liver cancer (hepatocellular carcinoma) or germ cell tumors — AFP production can increase. The AFP test simply measures the amount of this protein in your blood.
Why Is the AFP Test Done?
In Bangladesh, the AFP test is most commonly used for:
- Liver cancer screening — especially in people with chronic hepatitis B or cirrhosis, who are at higher risk. Regular AFP testing can help catch early signs of hepatocellular carcinoma.
- Monitoring treatment — for liver cancer or germ cell tumors, doctors follow AFP levels to see if treatment is working.
- Prenatal screening — as part of the triple marker test (along with hCG and estriol), AFP helps detect neural tube defects (like spina bifida) and chromosomal abnormalities (like Down syndrome) in the fetus.
Because hepatitis B infection is common in Bangladesh, many hepatologists recommend periodic AFP screening for carriers, combined with liver ultrasound.
How Is the AFP Test Performed?
The AFP test is a standard blood draw. No fasting or special preparation is required. A healthcare professional takes a small blood sample from your arm, which is sent to a laboratory. Results are usually ready within 1–3 days. If you are pregnant, inform your doctor or the lab technician so they can compare your results with pregnancy-specific reference ranges.
What Do AFP Test Results Mean?
AFP levels are reported in nanograms per milliliter (ng/mL). Normal ranges vary slightly between labs, but generally:
- Healthy adults: below 10–15 ng/mL
- Pregnancy: levels rise steadily and peak around 30 weeks; values depend on gestational age
An elevated AFP can have many causes, as shown in the table below. Important: A high AFP does not prove you have cancer. Your doctor will combine the result with imaging (ultrasound, CT, or MRI) and possibly a biopsy before making a diagnosis.
| Condition | Typical AFP range | Additional context |
|---|---|---|
| Chronic hepatitis or cirrhosis | 10–200 ng/mL | Often mildly elevated; may fluctuate with inflammation |
| Hepatocellular carcinoma (liver cancer) | Often >200 ng/mL | Some cancers produce only modestly elevated AFP; imaging is essential |
| Germ cell tumors (testicular, ovarian) | Variable, sometimes very high | Used for diagnosis and monitoring response to therapy |
| Normal pregnancy (single fetus) | Increases with gestation; median ~50–150 ng/mL at 30 weeks | Multiple gestation (twins, triplets) can cause higher levels |
| Neural tube defects (fetal) | Maternal serum AFP usually >2.5 multiples of the median (MoM) | Confirm with amniotic fluid AFP and ultrasound |
| Down syndrome (fetal) | Low maternal AFP (often <0.75 MoM) | Triple marker test combines AFP with other markers |
What Are the Limitations of the AFP Test?
While useful, the AFP test is not perfect. False positives can occur: for example, benign liver disease or pregnancy can elevate AFP. Conversely, false negatives are possible—up to 30–40% of early liver cancers do not produce enough AFP to be caught by this test. Additionally, different laboratories may use different assays, so always compare results from the same lab. For these reasons, AFP must be interpreted alongside other tests, especially liver ultrasound for cancer screening or detailed fetal ultrasound for pregnancy.
AFP Test Cost in Bangladesh
AFP testing is widely available in Dhaka and all divisional cities. Prices vary by location, lab reputation, and whether you request the test alone or as part of a package. The table below gives approximate ranges; always confirm the current price before visiting.
| Item | Approx. BDT range | Notes |
|---|---|---|
| AFP test (single) | ৳500 – 1,200 | Most private labs in Dhaka charge around ৳800–1,000 |
| Triple marker panel (AFP + hCG + uE3) | ৳1,500 – 3,000 | Commonly used in prenatal screening; includes AFP |
| Liver cancer screening package (AFP + ultrasound abdomen) | ৳2,000 – 4,000 | Hospital packages may offer slightly lower combined rates |
Prices are subject to change. Call the lab or hospital beforehand for an exact quote.

When Should You See a Doctor?
Consult a specialist if:
- You have chronic hepatitis B or cirrhosis and have never had AFP screening.
- Your AFP result is elevated (even slightly) — your doctor will decide if further imaging or a repeat test is needed.
- You are pregnant and your triple marker test shows AFP levels outside the expected range.
- You have unexplained weight loss, abdominal pain, or jaundice along with risk factors for liver cancer.
Remember: an abnormal AFP test is not a diagnosis. Take the report to a qualified doctor (hepatologist, oncologist, or obstetrician depending on your situation) who can guide you through the next steps.
Frequently Asked Questions
Do I need to fast or stop any medications before an AFP test?
Generally, no special preparation like fasting is required for the AFP test. However, certain medications or supplements may affect the results. It is important to inform your doctor about any medicines you are taking, including herbal or traditional remedies commonly used in Bangladesh. Your doctor will advise if any temporary adjustment is needed. Always follow the specific instructions given by your healthcare provider or the diagnostic lab.
Can the AFP test be used to monitor treatment for liver cancer after therapy in Bangladesh?
Yes, serial AFP measurements are often used to monitor response to treatment for hepatocellular carcinoma (liver cancer). A falling AFP level after therapy (e.g., surgery, ablation, or chemoembolization) may suggest a good response, while a rising level can indicate recurrence or progression. However, AFP alone is not sufficient; doctors in Bangladesh typically combine it with imaging (ultrasound, CT) and clinical examination. Discuss the monitoring schedule with your oncologist or hepatologist.
Is the AFP test part of routine pregnancy screening in Bangladesh?
The AFP test is commonly offered as part of the maternal serum screening (often called the ‘triple test’ or ‘quad test’) usually between 15 and 20 weeks of pregnancy. It helps assess the risk of neural tube defects (like spina bifida) and some chromosomal abnormalities. In Bangladesh, this screening is available at many private and public hospitals, but it is not mandatory. If you are pregnant and over 35 or have a family history, your gynecologist may recommend it. The test results must be interpreted alongside other markers and ultrasound findings.
How reliable is a normal AFP level for ruling out liver disease in patients with hepatitis B or C in Bangladesh?
A normal AFP level does not completely rule out liver disease or early liver cancer, especially in patients with chronic hepatitis B or C, which are common in Bangladesh. Some small or early-stage liver tumors may not produce elevated AFP. Therefore, a normal AFP should not replace regular imaging (e.g., ultrasound every 6 months) or other liver function tests. Your doctor will consider your AFP result in the context of your viral load, liver enzyme levels, and imaging findings.
Can the AFP test give false-positive or false-negative results, and what causes this?
Yes, false results are possible. A false-positive (elevated AFP without cancer) can occur in benign liver conditions like hepatitis, cirrhosis, or during pregnancy with certain fetal anomalies. A false-negative (normal AFP despite cancer) can happen in some slow-growing or non-AFP-producing tumors. In Bangladesh, it is important to note that sample handling errors or interferences from other proteins may also affect accuracy. That is why doctors never rely on AFP alone—they correlate it with imaging and serial testing.
