Hepatitis B and hepatitis C prevalence and treatment referral among Asian Americans undergoing community-based hepatitis screening.

Objectives: We sought to identify cross-sectional hepatitis B virus (HBV) and HCV prevalence among Asian Americans at a community health fair and to assess referral rates.

Methods: We determined HBV prevalence with hepatitis B surface antigen (HBsAg), antibodies to hepatitis B core antigen (anti-HBc), and antibodies to hepatitis B surface antigen (anti-HBs). We determined HCV prevalence with hepatitis C antibodies.

Factors affecting the quantitative liver-spleen scan in normal individuals.

The quantitative liver-spleen scan (QLSS) can estimate the functional hepatic mass and the organ volumes by precise measurement of sulfur colloid (SC) distribution. The normal range determined in prior studies was estimated from patients with absence of chronic liver disease in which intense fasting appeared to produce slightly abnormal values. This study was to determine the effect of fasting or fed status and colloid particle size on quantitative measurements from the QLSS in a small cohort of normal individuals.
