A DLC test is not specifically designed to diagnose allergies. However, it can provide some insights into allergic reactions indirectly. In allergic responses, eosinophil counts may increase, and healthcare providers may observe this in the DLC results. To diagnose allergies accurately, healthcare providers often use other tests, such as allergy-specific blood tests, skin prick tests, or oral food challenges, depending on the suspected allergen. These tests can identify specific allergens and assess the severity of allergic reactions. If you suspect allergies, consult your healthcare provider, who can recommend appropriate allergy testing methods and treatment options.
