Screening Tests for Serious and Opportunistic Infections

Disease Being Screened Screening Test(s) When to Screen
HBV
  • HBsAg

  • Anti-HBc

  • Anti-HBs

  • HBV DNA if HBsAg-positive or anti-HBc–positive and/or anti-HBs–positive

Before anti-TNFα, vedolizumab, or immunosuppressant use
HCV
  • HCV antibodies

  • HCV RNA (if anti-HCV–positive)

Before anti-TNFα or immunosuppressant use
Latent tuberculosis
  • Tuberculin skin test or QuantiFERON-TB Gold assay

  • Consider T-SPOT.TB assay if QuantiFERON-TB Gold is indeterminate.

  • Chest radiograph

Before anti-TNFα or vedolizumab use
HIV
  • 4th-generation antigen/antibody HIV-1/-2 immunoassay; if positive, obtain plasma HIV RNA level

Before anti-TNFα or immunosuppressant use
HPV
  • Papanicolaou test or HPV test (if available)

Before anti-TNFα or immunosuppressant use
VZV
  • Obtain history of chicken pox or shingles.

  • IgM/IgG anti-VZV

Before anti-TNFα or immunosuppressant use
Epstein-Barr virus
  • IgM/IgG anti–viral capsid antigen antibodies

  • IgM/IgG anti–Epstein-Barr nuclear antigen antibodies

  • IgM/IgG anti–early antigen antibodies

  • The Monospot test is not recommended for general use given its lack of specificity.

Before thiopurine use
anti-HBc, hepatitis B core antibody; anti-HBs, hepatitis B surface antibody; HBsAg, hepatitis B surface antigen; HBV, hepatitis B virus; HCV, hepatitis C virus; HPV, human papilloma virus; Ig, immunoglobulin; TNF, tumor necrosis factor; VZV, varicella zoster virus.
