Book AFP Test in Thanjavur | Alpha Fetoprotein Test

The Alpha Fetoprotein test is a blood test that measures the level of AFP, a glycoprotein produced primarily by the foetal liver, yolk sac, and gastrointestinal tract during foetal development. AFP is the dominant serum protein in the foetus, analogous to albumin in adults, and its concentrations are extremely high during foetal life before declining sharply after birth and reaching very low adult reference levels by the first year of life. In healthy adults, AFP is produced only in trace quantities, meaning any significant elevation above the adult normal range is clinically meaningful and warrants thorough investigation. AFP serves two clinically distinct purposes depending on the context in which it is measured. In adults, AFP functions as one of the most important tumour markers in oncology, elevated in hepatocellular carcinoma, the most common primary liver cancer, and in non-seminomatous germ cell tumours of the testis and ovary including yolk sac tumours, embryonal carcinoma, and mixed germ cell tumours. In pregnant women, maternal serum AFP measurement forms a critical component of antenatal screening for foetal neural tube defects, abdominal wall defects, and chromosomal abnormalities including Down syndrome and trisomy 18 as part of the second trimester triple or quadruple marker screening panel. In India, hepatocellular carcinoma is the sixth most common cancer and is strongly associated with the high prevalence of chronic hepatitis B and hepatitis C infections, alcoholic liver disease, and non-alcoholic fatty liver disease. AFP surveillance in high-risk patients is therefore a public health priority. The test is performed on a small blood sample drawn from a vein and completed in under five minutes.

Doctors prescribe an AFP test in the following situations: Screening for hepatocellular carcinoma in high-risk patients with liver cirrhosis, chronic hepatitis B, and chronic hepatitis C where biannual AFP measurement alongside liver ultrasound is the standard surveillance protocol recommended by international hepatology guidelines for early detection of liver cancer at a potentially curative stage. Diagnosing and staging non-seminomatous germ cell tumours of the testis and ovary where AFP is a primary tumour marker elevated in yolk sac tumours, embryonal carcinoma, and mixed germ cell tumours, and where pre-treatment AFP level is an essential component of the international germ cell tumour staging and prognostic classification system. Monitoring treatment response and detecting recurrence in hepatocellular carcinoma and germ cell tumour patients where serial AFP measurements after surgery, chemotherapy, or ablative therapy confirm whether treatment has achieved complete tumour elimination, with a falling AFP indicating response and a rising AFP signalling residual disease or recurrence. Antenatal screening for foetal neural tube defects in the second trimester where elevated maternal serum AFP between 15 and 20 weeks of gestation indicates increased risk of open neural tube defects including spina bifida and anencephaly, prompting targeted foetal ultrasound and further specialist evaluation. Investigating unexplained hepatic masses and chronic liver disease where AFP measurement alongside cross-sectional imaging helps characterise liver lesions and contributes to the differential diagnosis between hepatocellular carcinoma, benign hepatic adenoma, regenerative nodules, and metastatic liver disease. Evaluating children with abdominal masses where AFP is markedly elevated in hepatoblastoma, the most common primary liver tumour in children under five years, and where AFP level at diagnosis serves as both a diagnostic marker and a prognostic indicator guiding treatment intensity.

The AFP test measures the concentration of Alpha Fetoprotein in the blood serum, expressed in nanograms per millilitre (ng/mL) or International Units per millilitre (IU/mL). The normal reference range for non-pregnant adults is less than 10 ng/mL, with most healthy individuals having levels below 5 ng/mL. In pregnant women, AFP levels vary significantly by gestational age and are interpreted using multiples of the median rather than absolute values. Normal (Below 10 ng/mL) A result below 10 ng/mL is considered within the normal adult reference range and indicates no significant AFP elevation at the time of testing. In patients under active hepatocellular carcinoma surveillance, a consistently normal AFP alongside a normal ultrasound is reassuring, though it does not entirely exclude early liver cancer as a proportion of hepatocellular carcinomas do not produce significant AFP elevation. Mildly Elevated (10 to 400 ng/mL) A mildly elevated AFP warrants clinical investigation and cannot be attributed to malignancy without further evaluation. Benign causes including acute and chronic hepatitis, liver cirrhosis, and liver regeneration following injury can produce AFP elevations in this range. However, even mild elevation in a patient with cirrhosis or chronic viral hepatitis must be taken seriously and correlated urgently with liver imaging to exclude early hepatocellular carcinoma. Markedly Elevated (Above 400 ng/mL) AFP levels above 400 ng/mL in a patient with chronic liver disease or cirrhosis are highly specific for hepatocellular carcinoma and in many international guidelines are considered sufficient for a radiological diagnosis of hepatocellular carcinoma when accompanied by characteristic arterial enhancement on contrast-enhanced CT or MRI, without requiring histological biopsy. In germ cell tumour patients, very high AFP levels indicate a large tumour burden requiring urgent oncological management.

No fasting is required for the AFP test, as food and fluid intake do not affect AFP concentrations in the blood. The test can be performed at any time of day and is typically ordered as part of a scheduled liver cancer surveillance visit, an oncology tumour marker panel, or an antenatal screening assessment without any specific dietary preparation. Inform your doctor about known liver disease including hepatitis B, hepatitis C, cirrhosis, and alcoholic liver disease before the test, as these conditions can produce AFP elevations independent of malignancy and are essential context for accurate clinical interpretation. Active hepatitis flares can cause transient AFP elevations that may be misattributed to tumour development without this clinical context. For pregnant women undergoing second trimester maternal serum AFP screening, accurate gestational age documentation is critical as AFP values are interpreted as multiples of the gestational age-specific median and an incorrect gestational age can produce a falsely abnormal or falsely reassuring result. If you are undergoing serial AFP measurements for cancer surveillance or treatment monitoring, consistent use of the same laboratory and assay platform ensures reliable trend comparison across visits. Staying well hydrated before the blood draw facilitates easier venous access and a smooth collection experience.
