Hepatitis B Symptoms Quiz
For adults, symptom observations, possible exposure, and vaccination history can help organize a conversation about hepatitis B. Note when changes began and whether they affect daily activities. Hepatitis B can be present without symptoms, so screening decisions depend on clinical guidance and exposure history rather than how you feel.

Frequently Asked Questions
Common questions about this quiz, what it covers, and what your results mean.
These questions have not been clinically validated. Symptoms cannot diagnose hepatitis B; infection may be silent. New yellow eyes or skin needs care today. Confusion, vomiting blood, severe abdominal pain or fainting needs emergency care. Recent exposure needs prompt clinical advice.
Hepatitis B is an infection caused by the hepatitis B virus, also called HBV, that affects the liver. It can be present without symptoms. The CDC describes possible symptoms in Signs and Symptoms of Hepatitis B.
Vaccination history helps a healthcare professional discuss prevention and whether vaccination needs attention. It does not, by itself, establish your current infection status or immunity. Recommended screening may still be appropriate.
Hepatitis B infection is caused by HBV, not by fatigue or abdominal discomfort. Possible exposure through blood or sexual contact is important history to share with a clinician. Symptoms alone cannot tell whether exposure led to infection.
Hepatitis B can be present without symptoms. CDC recommends one-time screening for all adults aged 18 or older using HBsAg, anti-HBs and total anti-HBc. Pregnancy and ongoing exposure can require additional testing. Ask a healthcare professional how the recommendation applies to your history.
Possible symptoms include yellowing of the eyes or skin, dark urine, pale stools, fatigue, nausea, and abdominal discomfort. These symptoms can have other causes. New yellowing needs prompt medical evaluation; confusion, vomiting blood, severe abdominal pain, or fainting requires emergency care.
A clinician reviews symptoms, when they began, possible exposure, vaccination history, and relevant blood-test findings. Testing is needed to assess infection markers because symptoms can be absent or overlap with other conditions. Recent exposure also requires review of prevention and testing timing.
HBsAg testing with confirmation assesses a marker of current hepatitis B infection. A clinician interprets the report and chooses further evaluation. HBsAg alone does not establish immunity, infection stage or liver damage, and it does not include anti-HBs or total anti-HBc.
The complete three-marker screening panel includes hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and total hepatitis B core antibody (total anti-HBc). Together, these provide information that HBsAg alone cannot supply. A clinician interprets the combination in the context of your history.
Dark urine and pale stools can occur with acute hepatitis B, but neither change identifies hepatitis B as the cause. Note when the changes started and whether they persist, and discuss them with a healthcare professional. New yellowing of the eyes or skin needs prompt evaluation.
Contact a clinician promptly to review prevention options and testing timing, even if you feel well or have been vaccinated. Do not wait for symptoms or rely on one self-ordered test to settle the question. Tell the clinician what happened and when.
No. Hepatitis B can be present without symptoms, so feeling well cannot exclude infection. Clinical screening recommendations and exposure history still matter, even when there are few symptom concerns.
No. HBsAg alone does not establish immunity or supply the complete screening panel. A clinician can review HBsAg, anti-HBs, and total anti-HBc together with vaccination and exposure history.
