Overview
With changing trends in medicine, recommended lab investigations are changing. Blood cultures and blood counts are the mainstay for the treatment and prognosis. Other blood tests like ESR and CRP help in prognosis.Levels of ESR and CRP at admission may predict the severity and duration of hospitalization.[1]
Lab Work Up
- Cultures can be taken from Wounds, Pus & Blood. Blood cultures are positive only in few cases of mild infection/ community acquired cellulitis.[2] Blood cultures are significant when systemic spread occurs.
- In cases of abscess, gram staining and cultures of drained fluid may be helpful in further management of the condition.
- Total blood count increases. Leukocytosis is seen is most of the cases but in few toxin mediated cellulitis leucopenia may be observed.
- ESR and CRP can be used as prognostic indicators.New recommendations are more favorable towards the use of CRP compared to ESR.[3]
- Imaging may be considered when
- Bone involvement in suspected.
- Foreign body in-situ is one of the differential.
