Analytic Time:

4 days

Reference Range:

Non-reactive; positive with vaccine administration

Comments:

Part of initial diagnostic hepatitis profile.  Please indicate vaccine 
administration.  Immune status calculated.

Test
Limitations:

Nonspecific reaction may result from cross reactions in the immune 
"sandwich" complex.  Nonspecific reactions may include reactions with 
certain glycoproteins, such as concanavalin A, which interact with 
HBsAg.  Milliman and McMichael have shown that this hepatitis B binding 
substance is not antibody.  Any highly sensitive enzyme immunoassay 
system has the potential for nonspecific reaction in human serum or 
plasma.

Methodology:

Microparticle Enzymatic ImmunoAssay (MEIA)
