Below is a plain-language prep guide for the hepatitis b immunity status test in Kilauea, HI, including sample type and timing basics. The Hepatitis B Immunity Status Test is a blood test that checks whether you have protective antibodies against the hepatitis B virus.
What this test looks at
The test measures the presence of IgG and IgM antibodies against hepatitis B. These antibodies indicate whether your immune system has responded to the virus or vaccine. It does not measure the virus itself or liver function.
- Hepatitis B surface antibody (anti-HBs)
- Hepatitis B core antibody (anti-HBc)
- IgG antibodies
- IgM antibodies
Getting ready for the Hepatitis B Immunity Status Test
Routine orders rarely require special preparation. Confirm any timing or fasting details with the testing location at booking.
- Confirm with the lab whether fasting is required for this test.
- Stay hydrated by drinking water before your appointment.
- Bring a list of your current medications and vaccinations.
- Inform the lab if you have had a hepatitis B vaccine recently.
- Wear a short-sleeved shirt to allow easy access to your arm.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is typically not required for this test, but some labs may have specific instructions. Confirm with your lab.
Best time to collect
The test can be done at any time of day. There is no specific timing window unless your clinician advises otherwise.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- A written list of the medications and supplements you currently take
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What the collection involves
A healthcare professional will draw a small sample of blood from a vein in your arm using a needle. The sample is then sent to a laboratory for analysis.
Details worth confirming with the collection lab before your visit:
- Do I need to fast before this test?
- Are there any medications I should avoid before testing?
- When can I expect my results?
