Laboratory tests may include the following:

  • Liver function tests

  • Renal function tests

  • CBC count with differential

  • Hepatitis screen to assess for possible disease transmission by IVIG

  • Immunoglobulin levels to exclude IgA deficiency: If no IgA antibodies are found, then anti-IgA antibody titers should be obtained.

  • Rheumatoid and cryoglobulin levels, because IVIG can cause hematological complications

Finally, store a small amount of serum used before each infusion for analysis in the event of infectious disease transmission.
