AAP Immunization Schedule 2012 (including catch-up)




Serologic Testing


Serologic testing available for verifying immunization status (CDC Yellow Book 2010)
Children >6 Months of Age
Children >12 Months of Age
  • Diphtheria antitoxoid antibody
  • Tetanus antitoxoid antibody
  • Poliovirus neutralizing antibody for types 1, 2, 3
  • Hepatitis B surface antibody
  • Diphtheria antitoxoid antibody
  • Tetanus antitoxoid antibody
  • Poliovirus neutralizing antibody for types 1, 2, 3(1)
  • Hepatitis B surface antibody
  • Rubeola (measles) antibody
  • Mumps antibody
  • Rubella antibody
  • Varicella antibody (see note below)
  • Hepatitis A antibody
  • H. influenzae type b IgG
  • S. pneumoniae IgG for serotypes 7–14
(1)Titer to type 3 polio is often negative after immunization, not an indication to reimmunize

  • Note that varicella (VZV) IgG titers performed by commercial laboratories are not sensitive and may have a false negative rate of 15% or higher when compared to the gold standard FAMA (fluorescent antibody to membrane antigen). VZV IgM titers are also highly unreliable because of problems differentiating VZV IgG from VZV IgM under the assay conditions (e.g. an increase in VZV IgG could be mistakenly measured as VZV IgM)
