Negative

If positive, notification is made as soon as the positive culture is detected or identified.

Interpretation

Positive cultures of yeast and filamentous fungi are reported with the organism identification.

Positive cultures are usually an indication of infection and are reported as soon as detected. Correlation of culture results and the clinical situation is required for optimal patient management. A final negative report is issued after 30 days of incubation.
