Additional Information:
Indication: Immunodeficiency and vaccine responses
Background Information:
A patient may have normal levels of serum immunoglobulins and IgG subclasses but still be unable to respond effectively to pathogens even after vaccination. Specific antibody responses should be measured against a panel of protein and carbohydrate antigens. Protein antigens include tetanus and diphtheria toxoid and polysaccharide antigens include pneumococcus and haemophilus influenzae Type B. Investigation of specific antibody responses is useful in the assessment of patients with recurrent bacterial sepsis, invasive bacterial disease and putative immune defects. They can also be useful in assessing immune reconstitution post bone marrow transplant, asplenic patients and assessment of protective antibody levels as an indication for re-vaccination
