Case 3: Appropriate Serologic Testing

You answered:

B Hepatitis A, B, and C serologies

This answer is correct, but other answers are also correct. Injection drug use is the primary route of HCV infection, though a baseline HCV serology (anti-HCV antibody) is recommended in all HIV-infected patients, regardless of mode of transmission. Knowledge of HCV status is useful for interpretation of liver enzyme abnormalities, and a positive result should prompt further evaluation to assess the stage of disease and need for therapy. Male-male sex and injection drug use also place this patient at higher risk of having hepatitis A and B virus infection. HbsAg is indicated to rule out chronic HBV infection, and HbsAb or anti-HBc determine need for vaccination. Similarly, the total-HAV antibody is used to determine the need for hepatitis A vaccination.

Choose another answer:

A anti-Toxoplasma IgG
C anti-Histoplasma IgG
D Venereal Disease Research Lab (VDRL) or Rapid Plasma Reagin (RPR)
E A, B, and D
