Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you experience persistent dry mouth, difficulty swallowing, or symptoms of salivary gland problems. It could also be part of an evaluation for autoimmune disorders or chronic infections affecting saliva production.
What to Expect Before the Test
No special preparation is needed. You’ll provide a saliva sample, often collected by gently rolling a cotton swab in your mouth for a few minutes. This is usually done in a clinic or lab setting.
What the Test Results Mean
Results are qualitative, meaning they indicate whether markers are present or absent rather than a specific value. Abnormal findings may suggest gland dysfunction, inflammation, or other underlying conditions that require further medical evaluation.
Common Conditions Linked to This Test
This test can help diagnose or monitor conditions such as salivary gland infections (sialadenitis), Sjogren’s syndrome (an autoimmune disorder affecting saliva and tears), or other salivary gland disorders that may cause dryness or pain.

Frequently asked questions
Salivary gland function is critical for oral health, digestion, and preventing infections. Abnormal results may prompt additional testing, such as imaging (e.g., sialography) or further blood tests to pinpoint the cause of symptoms like dry mouth or swelling.
