Allergen, Food, Malt
Also known as: MALT
Use
The Allergen, Food, Malt test is used to measure the level of immunoglobulin E (IgE) specific to malt allergens in the blood. This measurement helps in evaluating allergic reactions and symptoms in patients with a suspected allergy to malt, which can be found in barley and wheat products. The test results can guide clinicians in diagnosing and managing food allergies, and in assessing the risk of IgE-mediated responses in patients.
Special Instructions
Multiple patient encounters should be avoided to reduce variability. Serum should be separated from cells as soon as possible or within two hours of collection to ensure sample integrity. A minimum volume of 0.25 mL of serum is required for the test. For multiple allergen tests, refer to the detailed allergen specimen collection instructions available on the ARUP website.
Limitations
The concentrations of allergen-specific IgE detected by this test may not correlate directly with the degree of clinical response in patients. A negative result does not exclude the possibility of clinical allergy or anaphylactic reactions. It is important to correlate laboratory results with clinical history and other in vivo tests to determine the significance of the findings. A result in the range of 0.10-0.34 kU/L has undetermined clinical relevance and should be interpreted by a specialist.
