Haemophilus Influenzae: Test and Diagnosis

1st order laboratory parameters – obligatory laboratory tests.

  • Pathogen culture* from blood, CSF, pus, etc. (Caveat: rapid processing, because low environmental resistance).
  • Microscopic preparation* and detection of capsular antigens as rapid detection in meningitis (meningitis).

* Direct or indirect detection of the pathogen is reportable under the Infection Protection Act (IfSG), if the evidence indicates an acute infection.

Laboratory parameters 2nd order – depending on the results of the history, physical examination and the obligatory laboratory parameters – for differential diagnostic clarification.

  • Small blood count
  • Inflammatory parameters – CRP (C-reactive protein) or PCT (procalcitonin).
  • Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT).
  • Renal parameters – creatinine, urea.
  • Coagulation parameters – Quick, INR, PTT
  • Blood cultures, smears from drains, etc.
