Interferences & limitations
- Extended time between collection and testing: delays in processing the sample can lead to the degradation of viral particles which could affect the test’s sensitivity and accuracy
- Temperature sensitivity: HBV DNA is sensitive to temperature changes
If the sample is exposed to high temperatures during transport, the viral DNA may degrade, leading to false-negative results or undetectable viral load.
- Sample nature: Serum or plasma
- Recommended volume: 5 mL
- Type of container: EDTA or Serum tube
<2h at room temperature
