Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Ariboflavinosis is a nutritional disorder caused by vitamin B2 (riboflavin) deficiency. This condition can manifest with symptoms including sore throat, mouth and lip inflammation, tongue redness, and skin problems. A specific blood test is required to accurately diagnose this vitamin deficiency.
Recommended Test
Vitamin B2 (Riboflavin)
This test directly measures vitamin B2 (riboflavin) levels in the blood to diagnose ariboflavinosis. Low riboflavin levels confirm the deficiency that causes symptoms such as sore throat, mouth inflammation, cracks at the corners of the mouth, tongue redness, and skin problems including seborrheic dermatitis.

Diagnosing Ariboflavinosis
Because the symptoms of ariboflavinosis can overlap with other nutritional deficiencies or medical conditions, a definitive diagnosis relies on measuring vitamin B2 levels in the blood. This ensures that appropriate supplementation and dietary changes can be implemented to correct the deficiency.
Understanding Ariboflavinosis Symptoms
Vitamin B2 deficiency can cause a range of symptoms affecting the mouth, throat, and skin. These include cheilosis (cracks on the lips), angular stomatitis (sores at mouth corners), magenta tongue (inflammation and redness of the tongue), and seborrheic dermatitis (moist, scaly skin inflammation). Early detection through testing allows for prompt treatment.
