Primary immunodeficiency

The following panels of tests are available for investigating patients:


Grouping is frequently based on the specific fault in the immune system. This may include:

  • B Cell antibody deficiency causes mainly recurrent bacterial infections
  • T cell deficiency causes viral, protozoal and fungal infections
  • Combined T and B cell deficiencies
  • Defective phagocytes
  • Complement deficiencies cause mainly bacterial infection

There are no 'screening tests' for immune deficiency. In cases with recurrent bacterial infection it may be sensible to start by measuring immunoglobulins, but we advise discussing individual cases early on.
