Ordering the Hepatitis Exposure Panel
Ordering the Hepatitis Exposure Panel helps check for exposure to Hepatitis A, Hepatitis B, and Hepatitis C by measuring specific antigens and antibodies in your blood. This test can show if you have a current or past infection, or if you have developed immunity, which is especially useful for people who may not have symptoms. Interestingly, some people can carry hepatitis viruses without feeling sick, but they can still spread the virus to others.
When ordering the Hepatitis Exposure Panel, you gain several specific benefits:
- Detects both recent and past exposure to Hepatitis A, B, and C viruses.
- Shows if you have developed immunity after vaccination or previous infection.
- Helps identify silent carriers who may not show symptoms but can transmit the virus.
- Guides your doctor in choosing the right follow-up tests or treatments.
- Supports safe participation in activities like blood donation or certain jobs.
Who Should Consider Hepatitis Screening
People who have traveled to areas where hepatitis is more common, or who have shared personal items like razors or toothbrushes, may benefit from this screening. For example, someone who recently started a new job in a healthcare setting might want to check their hepatitis status to protect themselves and others.
Ordering this panel may also be helpful in these situations:
- Starting a new relationship and wanting to know your hepatitis status.
- Preparing for surgery or a medical procedure that involves blood products.
- Having a family member diagnosed with hepatitis and wanting to check your own exposure.
- Participating in community service or volunteer work that involves close contact with others.
- Being adopted from or having lived in a country where hepatitis is more common, even if you feel healthy.
This screening is important because it can detect hepatitis exposure before symptoms appear, allowing for early action and reducing the risk of spreading the virus. Delaying this test could mean missing the chance to catch an infection early, which may lead to more complicated health issues or unknowingly passing the virus to others.
Preparing for Hepatitis Antibody and Antigen Testing
Fasting is not required before this blood test, so you can eat and drink as usual. Always follow any instructions your doctor or healthcare provider gives you to make sure your sample is collected properly and your results are as helpful as possible.
Labs Included When Ordering Your Hepatitis Exposure Panel
| Test Name | Reference Range | What This Biomarker Means | Low and High Levels of This Test |
|---|---|---|---|
| Hepatitis A Surface Antibody | Negative: <1.0 S/CO Positive: ≥1.0 S/CO |
This marker shows if your body has made antibodies against Hepatitis A, either from past infection or vaccination. A positive result means you are protected from Hepatitis A. |
High levels mean you have immunity to Hepatitis A, either from vaccination or past infection.
Low levels mean you have not been exposed to Hepatitis A or have not developed immunity. |
| Hepatitis B Surface Antigen | Negative: <1.0 S/CO Positive: ≥1.0 S/CO |
This test checks for the presence of Hepatitis B virus in your blood. A positive result means you may have an active Hepatitis B infection and can spread the virus to others. |
High levels mean you have an active Hepatitis B infection and may be contagious.
Low levels mean no active Hepatitis B virus was found in your blood. |
| Hepatitis B Surface Antibody | Negative: <10 mIU/mL Positive: ≥10 mIU/mL |
This marker shows if you have developed immunity to Hepatitis B, either from vaccination or recovery from a past infection. A positive result means you are protected. |
High levels mean you are immune to Hepatitis B, usually from vaccination or past infection.
Low levels mean you are not protected against Hepatitis B and may be at risk if exposed. |
| Hepatitis B Core Antibody | Negative: <1.0 S/CO Positive: ≥1.0 S/CO |
This test detects antibodies made in response to the core part of the Hepatitis B virus. A positive result can mean a current or past infection, but not immunity from vaccination. |
High levels mean you have been exposed to Hepatitis B, either currently or in the past.
Low levels mean you have not been exposed to the core part of the Hepatitis B virus. |
| Hepatitis C Antibody | Negative: <1.0 S/CO Positive: ≥1.0 S/CO |
This marker shows if you have ever been exposed to the Hepatitis C virus. A positive result means you have been exposed and may need more tests to check for active infection. |
High levels mean you have been exposed to Hepatitis C and may have an active or past infection.
Low levels mean you have not been exposed to Hepatitis C. |
Reference ranges can change over time. For the most current values, visit the Quest Diagnostics lab test directory.
