|Additional information||A marker of HBV infection at some indefinite time in the past, this assay may be positive when anti-HBs is negative. Although this test can be helpful in implicating a possible viral etiology of unexplained cirrhosis or hepatocellular carcinoma, it has no role in the diagnosis of acute HBV infection.
This test is not FDA approved for donor screening. For pre-transplant donor screen see Pre-Transplant Send out (PTXID).
Positive results are automatically forwarded to California public health per regulations. However, this does not absolve the ordering provider from any additional reporting if such is required.
