Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like white patches in your mouth, persistent sore throat, or unexplained oral discomfort, especially if you have weakened immunity or recent antibiotic use.
What to Expect Before the Test
No special preparation is needed. You’ll provide a saliva sample, often collected by gently scraping your inner cheek or mouth. Avoid eating, drinking, or brushing your teeth for 30 minutes before the test.
How the Test Works
A lab technician will culture your saliva sample on a special growth medium to detect and identify *Candida* yeast. Positive results appear as fungal colonies after incubation.
What the Results Mean
A positive result confirms the presence of *Candida* in your saliva, supporting a diagnosis of oral candidiasis. A negative result means no detectable yeast, but symptoms may still warrant further evaluation.
Reference range
Negative for Candida species. Presence of Candida sp. in saliva may indicate oral candidiasis (thrush), colonization, or carrier state. Clinical correlation required.N/A
Patient should avoid eating, drinking, smoking, chewing gum, or using oral hygiene products (mouthwash, toothpaste) for at least 30-60 minutes prior to specimen collection. Do not collect sample within 24 hours of antifungal or antibiotic use unless clinically indicated. Rinse mouth with sterile water prior to collection if instructed.
Clinical interpretation
