Special Instructions

Limitations
A negative stain result does not exclude the possibility of a fungal infection. False negatives may occur due to sampling errors or a low number of organisms in the specimen. Thus, a negative result should not be the sole basis for ruling out fungal infections, and clinical correlation is required.
