Range / Level of HBsAg Test
The HBsAg test results are typically reported as:
- Negative (or Non-Reactive): Less than 0.05 IU/mL (International Units per milliliter)
- Positive (or Reactive): 0.05 IU/mL or greater
The levels of HBsAg can vary depending on the stage of infection and the individual's immune response. Here are some general guidelines on the ranges of HBsAg levels:
- Low levels (0.05-10 IU/mL): May indicate a low viral load or early stages of infection
- Moderate levels (11-100 IU/mL): May indicate a moderate viral load or chronic infection
- High levels (101-1,000 IU/mL): May indicate a high viral load or active replication of the virus
- Very high levels (greater than 1,000 IU/mL): May indicate a severe infection or liver damage
Keep in mind that these ranges are approximate and may vary depending on the specific test and laboratory. It's important to consult with a healthcare professional to interpret the results and determine the appropriate course of action.
Additionally, the HBsAg test may also be reported as:
- Quantitative: Provides a numerical value of the HBsAg level
- Qualitative: Reports the presence or absence of HBsAg (positive or negative)
It's important to note that the test results should be interpreted in conjunction with other laboratory tests, such as liver function tests and hepatitis B virus DNA (HBV DNA) levels, to get a comprehensive picture of the infection.
