Common questions
Which Hepatitis B Screening option should I choose?
Choose Laboratory Method for the standard lab-based HBsAg screen, especially for routine check-ups, pre-employment, pregnancy, or confirmatory needs. Choose Rapid Test when you need a faster same-day screening result; reactive rapid results may still need lab confirmation.
What does a reactive result mean?
A reactive result suggests active Hepatitis B infection and usually leads to further testing to learn more.
Is Hepatitis B preventable?
Yes. A safe and effective vaccine is available, which is why screening and prevention go hand in hand.
Is my result confidential?
Yes. Your results are private and shared only with you.
