- hepatitis B infection
Clinical significance:
- virus DNA level predicts risk of hepatocellular carcinoma
- > 100,000 copies/mL threshold for treatment
Specimen:
1) whole blood (ACD or EDTA)
2) liver
3) store body fluids at 4 degrees C
4) store tissue at -20 degrees C or below
Notes:
- molecular testing is more sensitive than serology
- quantitative HBV DNA is useful for monitoring response to therapy
