Testing for antibodies

Blood tests can detect different levels and types of antibodies.

Functional antibodies:

These are antibodies against tetanus, haemophilus influenza type B and pneumococcal infections.
People who have been immunised should have normal levels of antibodies.
If there is a problem with the immune system or if the person has not been sufficiently vaccinated, these levels may be low.
Low levels mean there may be at risk of recurrent infections.

Aspergillus antibodies:

Aspergillus is a common mould that can cause a wide range of lung conditions.
Checking for antibodies to this mould can help to diagnose aspergillus associated diseases and monitor response to treatment.
