Serum is the preferred specimen. Use Gold Serum Separator Tube-Clot Activator & Gel. REMARK: Plasma is an acceptable alternative specimen in a lavender (EDTA) tube, same volume required.
Unacceptable Conditions
Do not use serum specimens that are heat-inactivated, pooled, grossly hemolyzed, or contain obvious microbial contamination. Performance has not been established for the use of cadeveric specimens or the use of boody fluids other than human serum or plasma.
Storage/Transport Temperature
For the CHOP enterprise, a total of 2-4 ml of blood (for every 2-3 HIV and Hepatitis tests ordered) should be collected and submitted at room temperature to the laboratory.
For outside clients, it is recommended that serum or plasma specimens be removed from the clot, red blood cells, or separator gel as soon as possible after collection and before shipping specimens.
Volume Required
4 ml of blood
Minimum Required
2 ml of blood
Phlebotomy Draw

Utility
The detection of HBV core IgM is an indicator of acute infection with Hepatitis B virus (HBV); can occasionally persist at low levels during chronic infection. IgM antibody to core antigen (IgM anti-HBc) is present at the onset of acute hepatitis B infection and persists for 3-12 months before declining to indetectable levels. A positive test for IgM anti-HBc is diagnostic for acute or recent HBV infection and may be the only marker present in acutely ill neonates and patients with acute fulminant HBV infection who may not have detectable HBsAg.
