EMOCOLTURE
• Numero raccomandato: 3 set
• Quantità: 60 ml x adulti, distribuire 10 ml in 3
bottiglie per aerobi e 10 ml in 3 bottiglie per
anaerobi
• Timing: prelevare le tre emocolture una dopo
l’altra nell’arco di 30 minuti da tre siti diversi
• SENSIBILITA’: da 50 a 75 %
The median Candida concentration
within a first positive blood culture is 1
CFU/mL
26% - 65% of positive blood cultures
have <1 CFU/mL.

What are the best tests for diagnosing candidaemia?
Specimen Test
Considerations
Remarks/Recommendations
Serum
Mannan and AntiMannan
• Combined detection
RECOMMENDED
Serial determinations may be
necessary. High NPV
Other antibodies (such
as Serion ELISA
classic)
• Limited data for
candidemia
ß-D-Glucan
• Not specific for Candida
Septifast
• Limited data for
candidemia
No recommendation
In house PCR
• No third party validation
data available
No recommendation
No recommendation
RECOMMENDED (for Fungitell) No
recommendation for other tests. Serial
determinations are recommended
(twice a week). High NPV. Not
validated in children
Beta D Glucan

3 different tests (2 Japan, 1 USA)
Variable quality of data: retrospective vs. prospective;
heterogenous
 Different cut offs used
 “pangungal” – except cryptococcus and mucorales


Sensitivity 45-70%; specificity and NPV high

High false-positives: up to 30% in ICU- bacteraemia,
antibiotics, pre-/analytical contaminations
Influence of ongoing antifungal
prophylaxis/therapy not known
 Costs, complex analytical procedures: automated
assay in the pipeline


• Prefer echinocandin for severe illness
• Prefer echinocandin in patients with
