What's this test for?

This test is ideal if you're currently being treated for chronic hepatitis B and your virus levels aren't improving the way expected. It looks at the specific strain (genotype) of hepatitis B you have and checks whether the virus has developed changes that make it resistant to antiviral medications. This helps explain why a treatment might not be working as well as it should.

What's included in this test?

This test looks at your hepatitis B genotype, which is basically the specific version or family of the virus you're carrying, since different genotypes can behave differently and respond differently to treatment. It also screens for mutations in two areas: places tied to antiviral drug resistance, and the BCP/precore region, which can affect how actively the virus replicates and how severe the infection may become.

What happens after I get my results?

Your results will appear in your account with an explanation of what your genotype and any resistance mutations mean. If mutations linked to drug resistance are found, a common next step is adjusting which antiviral medication is used going forward, so this information is worth acting on promptly. You can download a standard lab report from your account at any time, and if you test again in the future, you can compare results side by side using the trends feature. If your results show signs of worsening liver function or very high viral activity, seek medical care promptly.

How can I naturally support liver health during hepatitis B treatment?

While no natural remedy replaces antiviral treatment for hepatitis B, some everyday habits help support your liver as it does its job. Cutting out alcohol, avoiding unnecessary medications that stress the liver (like high-dose acetaminophen), eating a balanced diet with plenty of vegetables, and keeping a healthy weight can all reduce extra strain on the liver. Staying hydrated and getting regular movement also support overall liver function alongside your treatment plan.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. This type of testing involves detailed genetic analysis of the virus, which is why it takes a bit longer than a standard blood test. You'll be notified as soon as your results are available in your account.

Who should consider this test?

This test is best suited for people already diagnosed with chronic hepatitis B, especially those who are on antiviral therapy and whose viral load isn't dropping as expected. It's also useful for anyone whose treatment plan is being reconsidered, since knowing the genotype and resistance profile helps guide which medication might work better. If you've been on the same hepatitis B medication for a long time without recent monitoring, this test can reveal whether the virus has adapted.

What symptoms indicate I may need this test?

Signs that your current hepatitis B treatment may not be working include persistently elevated liver enzymes, fatigue that isn't improving, ongoing jaundice (yellowing of skin or eyes), or lab results showing your viral load isn't going down despite being on medication. If you've noticed these signs while on antiviral therapy, this test can help identify why. It's less about new symptoms and more about treatment not performing as expected.

What is hepatitis B genotype and why does it matter?

A genotype is essentially a genetic subtype of the hepatitis B virus, labeled A through H. Different genotypes are more common in different parts of the world and can vary in how quickly the disease progresses and how well certain treatments work. Knowing your genotype gives useful context for what to expect from your infection and treatment path.

What does it mean if drug resistance mutations are found?

If your results show resistance mutations, it means the virus has changed in a way that lets it survive despite the antiviral medication you're taking. This doesn't mean treatment has failed completely, but it does suggest a medication switch or adjustment may help control the virus better. This is a good time to review your current antiviral regimen and consider retesting after any treatment change to confirm it's working.

How often should I retest?

If you're stable on treatment and your viral load is well controlled, this specific test usually doesn't need to be repeated often. However, if your medication is changed due to resistance, or if your viral load rises again in the future, retesting can confirm whether the new approach is working or whether new resistance patterns have developed. Routine viral load monitoring in between is more frequent than this particular resistance/genotype test.
