Required investigations

Suggested Investigations:

  • Blood cultures x2, PRIOR to antibiotic administration
  • Imaging of injection sites, looking for abscesses, DVT etc.
  • Consider disseminated infection such as septic pulmonary emboli based on symptoms and signs. Consider further chest imaging (CXR or CT) if suspicious.
  • Consider endocarditis in patients with confirmed blood stream infection or where there are clinic signs.
  • Review Staph. aureus blood stream infection if SAB is confirmed.
  • Recommend: HIV test, Hepatitis C antibody test, and Hepatitis B surface antigen test. If patient has previously tested positive for Hepatitis C antibodies and is not known to have chronic infection then send Hepatitis C PCR or antigen - discuss with Virology.
