Hepatitis A Immunity Test

A blood test for hepatitis A (HAV IgG) antibodies — confirming whether a patient has protective immunity to hepatitis A through prior infection or vaccination. Available at 395 Kč without a prescription, collected at any Prague Unilabs collection point. Hepatitis A is a liver-transmitted viral illness spread primarily through contaminated food and water; it is endemic in many travel destinations across Asia, Africa, Central and South America, and parts of Eastern Europe. The test is relevant for travellers preparing for high-risk destinations who want to confirm whether their previous vaccination or natural exposure has produced lasting immunity, and for healthcare and food service workers subject to occupational immunity checks. Results in 4 business days. Rated 4.89/5 from 73 reviews.

The Hepatitis A immunity test at Unilabs CZ measures anti-HAV IgG antibodies — the long-term immunoglobulin G antibodies that confer lasting protection against hepatitis A virus (HAV) infection. This is distinct from anti-HAV IgM, which indicates a current or very recent infection; the IgG test is the marker of established immunity, whether from previous illness or completed vaccination. Hepatitis A is a notifiable disease in the Czech Republic and across Europe, spread by the faecal-oral route — primarily through contaminated water, uncooked shellfish, fresh produce, and close contact with infected individuals. The Czech vaccination schedule recommends HAV vaccination for travellers to endemic regions, food handlers, healthcare workers, and patients with chronic liver disease. However, vaccine records are frequently incomplete, and a significant proportion of Czech adults aged 40+ have natural immunity from childhood exposure (when HAV infection was more common) without having been formally vaccinated. The practical scenarios where this test adds value include: (1) pre-travel preparation for destinations where HAV is endemic (Southeast Asia, India, Egypt, Turkey, Morocco, South America, Central America) — checking whether a booster is needed before paying for a vaccine that may be unnecessary; (2) occupational health compliance for food handlers, healthcare workers, and water treatment employees; (3) confirmation of vaccine effectiveness for immunocompromised patients where seroconversion after vaccination cannot be assumed; and (4) post-exposure follow-up for contacts of confirmed HAV cases. A positive anti-HAV IgG result indicates protective immunity — no vaccination is needed. A negative result means the patient is susceptible to infection and should consider vaccination before travel to endemic areas. The test requires only a venous blood draw; no fasting or special preparation is needed. Results are delivered to the patient's online account within 4 business days.
