Why This Test Is Done

Your doctor may order this test if you have symptoms like liver problems, abnormal liver tests, or if you’ve been exposed to hepatitis viruses. It’s also used to monitor treatment progress in people with chronic hepatitis.

What to Expect Before the Test

You’ll likely have a small sample of liver tissue taken during a procedure called a biopsy. This is usually done under sedation and may cause mild discomfort afterward. Follow your doctor’s instructions for preparation.

How the Test Works

The tissue sample is analyzed in a lab to detect and measure viral RNA. Special techniques, like polymerase chain reaction (PCR), identify and quantify the virus’s genetic material.

What the Results Mean

Results show the viral load (how much virus is present). Higher levels may mean the virus is more active, while lower levels suggest the body is responding to treatment or the virus is less active.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a high viral load mean?
A high viral load often means the virus is actively replicating in your liver, which may require stronger treatment or closer monitoring to control the infection.
How long does it take to get results?
Results typically take 1–3 business days, depending on lab processing times. Your doctor will contact you once they’re ready.
Can I eat or drink before this test?
You may need to follow specific fasting or preparation instructions, depending on the biopsy procedure. Always ask your doctor or lab technician for exact guidelines.
