Frequently Asked Questions
What does a fungal culture from eye swab detect?
It identifies pathogenic fungi such as Aspergillus, Candida, Fusarium, and other filamentous fungi causing ocular infections like fungal keratitis or fungal conjunctivitis.
How is the eye swab sample collected?
A sterile swab is gently rubbed over the affected conjunctival surface or corneal lesion by the clinician. The sample is then transported in appropriate medium to the microbiology lab for inoculation and incubation.
How long does it take to get fungal culture results?
Fungal cultures typically require 3 to 7 days for initial growth, with definitive identification and susceptibility testing taking up to 7 to 14 days depending on the organism.
Is fasting required before this test?
No, fasting is not required for a fungal culture from eye swab as it is a local specimen collection procedure.
What conditions lead to this test being ordered?
It is ordered when fungal keratitis or ocular fungal infection is suspected — presenting with eye pain, redness, blurred vision, photophobia, or a characteristic corneal ulcer with feathery margins.
Can medications affect the culture results?
Yes, prior use of antifungal eye drops or systemic antifungals can suppress fungal growth and lead to false-negative results. Inform your doctor about any recent ocular medication use before sample collection.
