When does a doctor order DUAL MARKER (blood test)?

Doctors order DUAL MARKER (blood test) when a patient reports jaundice, dark urine, pale stools, persistent fatigue, nausea, or upper right abdominal pain. It is also routinely ordered before starting hepatotoxic medications (statins, anti-TB drugs, anticonvulsants) and periodically during their use.

Who should get DUAL MARKER (blood test) done in Kolkata?

West Bengal is reported to have one of India's highest hepatitis B carrier rates, estimated at around 4 to 5% of the population. Combined with a diet heavy in mustard oil, sweets, and fried foods, liver disease risk is significant for working adults across Ballygunge, Alipore, and Lake Gardens. DUAL MARKER (blood test) is a two-marker screening often offered in the first trimester as part of prenatal screening together with nuchal translucency ultrasound. Doctors order it for routine prenatal risk assessment, when maternal age is advanced, or after abnormal ultrasound findings. NAFLD affects an estimated 25 to 35% of India's urban adults , the majority unaware. Regular liver testing in Kolkata's residential areas including New Town and Jadavpur enables lifestyle intervention before irreversible scarring occurs. Patients recovering from hepatitis, those in alcohol recovery, and anyone with persistently unexplained fatigue also benefit from regular liver monitoring.

What conditions can DUAL MARKER (blood test) help diagnose?

Very high ALT and AST (10–50× normal) with normal ALP suggests acute hepatocellular injury , viral hepatitis, drug toxicity, or ischaemia. Predominantly elevated ALP and GGT with modest transaminases suggests bile duct obstruction or primary biliary cholangitis. An AST:ALT ratio above 2 suggests alcoholic hepatitis. Persistently low albumin with elevated bilirubin indicates advanced cirrhosis.

What do DUAL MARKER (blood test) results mean?

ALT above 56 U/L or AST above 40 U/L signals hepatocyte stress. The pattern matters: ALT greater than AST typically suggests NAFLD or viral hepatitis. An AST:ALT ratio above 2 points to alcoholic hepatitis. High ALP with normal transaminases suggests bile duct disease rather than liver cell damage. Low albumin alongside high bilirubin indicates serious loss of liver function.

How often should DUAL MARKER (blood test) be repeated?

Adults with no liver risk factors and a previously normal result: annually. Patients with NAFLD or treated hepatitis: every 6 months. Patients on hepatotoxic medication: baseline before starting, then at 1 month, 3 months, and every 6 months during treatment. Patients with active liver disease: at intervals specified by their gastroenterologist.
