Key facts

• Hepatitis B virus surface Ab [Presence] in Serum, Plasma or Blood by Rapid immunoassay
• Hepatitis B virus surface Ab
• Hepatitis B surface Ab (HBsAb) rapid tests are available in test strip and cassette formats from manufacturers in various countries including the US, Singapore, and China. (As of 8/25/2014, no HBsAb rapid test kits are approved for use in the United States). Hepatitis B surface Ab (HBsAb) rapid tests are used to test human blood for the presence of HBsAb.
