Practical checklists for dental care, surgery, piercing, tattoos, acupuncture, nail care, and other situations involving blood or skin-piercing tools.
Being HBsAg positive does not mean you cannot receive dental care, surgery, acupuncture, or ordinary medical services. Proper medical and dental settings should use standard precautions for every patient: gloves, sharps safety, cleaning and disinfection, sterilization, disposable supplies, and safe injections.
You also do not need to disclose hepatitis B status to barbers, restaurants, coworkers, or schools because of ordinary daily contact. The main situations to think about are those that pierce skin, contact blood, reuse instruments, or handle open wounds.
Before dental care, surgery, endoscopy, acupuncture, tattooing, piercing, nail or foot care, or any service that may involve bleeding, ask: Are needles single use? Are reusable instruments cleaned, packaged, and sterilized properly? Is there a sharps container? Do staff wear gloves and change them between clients? How are work surfaces cleaned if blood may contaminate them?
If the provider avoids these questions, says there is absolutely no hepatitis B here so no precautions are needed, uses needles of unclear origin, or opens single-use tools where you cannot see, consider choosing a more reliable provider. The key question is not whether they accept people with hepatitis B, but whether they use infection control for everyone.
For medical, dental, surgical, endoscopy, delivery, dialysis, chemotherapy, immune-suppressing treatment, or transplant evaluation settings, tell the clinician your HBsAg result, HBV DNA, ALT/AST, cirrhosis status, and antiviral medicines. This is not for isolation; it helps assess liver function, bleeding risk, drug interactions, reactivation risk, and perioperative medication planning.
For tattoos, piercing, acupuncture, and nail services, disclosure may involve privacy, local law, and culture. Whether or not you disclose, you can insist on single-use needles, proper sterilization, and no sharing of tools that pierce skin or may carry blood.
Single-use needles should be opened before use and discarded immediately into a sharps container afterward. Reusable instruments should not simply come out of a drawer; staff should be able to explain cleaning, packaging, and sterilization. Staff should wear gloves when touching blood, mucous membranes, wounds, or contaminated tools, and should change gloves and perform hand hygiene between clients or steps.
Do not share razors, blades, lancets, injection needles, piercing needles, tattoo needles, foot-care blades, nail clippers, or personal tools that may have blood on them. Home glucose lancets, injection needles, and blood-testing lancets should not be shared, even within family.
If you are injured by a used needle, blade, or instrument, or someone else's blood contacts your eyes, mouth, open wound, or broken skin, wash skin with running water and soap. For eye or mouth exposure, rinse with clean water. Do not squeeze the wound, repeatedly burn it with harsh chemicals, or wait for symptoms.
Contact emergency care, an occupational exposure clinic, infectious disease care, or local public health service promptly. Describe the exposure time, tool type, visible blood, the source person's HBsAg status if known, your hepatitis B vaccine record, and previous anti-HBs results. CDC post-exposure guidance uses vaccination history, anti-HBs level, and source status to decide whether HBIG, vaccine, or follow-up testing is needed.
Choose providers who can explain single-use needles, instrument sterilization, and sharps disposal. Before medical or dental procedures, tell clinicians about hepatitis B, liver tests, medicines, and cirrhosis status. Do not share any tool that pierces skin or may carry blood. After needle stick or blood contact with mucous membranes or open wounds, wash immediately and seek care promptly. Keep vaccine records and anti-HBs results on your phone for post-exposure decisions.
