Allergen, Food, Flaxseed/Linseed IgE
Also known as: FLAX
Use
This test is used for the quantitative measurement of allergen-specific IgE antibodies to flaxseed/linseed in human serum. It aids in the diagnosis of allergic diseases and provides critical information for the management of patients with suspected food allergies. The results should be interpreted in conjunction with the clinical history and other diagnostic tests as allergen concentrations may not fully correlate with the degree of clinical response.
Special Instructions
Avoid multiple patient encounters for this test. Separate serum from cells as soon as possible, preferably within two hours of collection. For multiple allergen orders, refer to ARUP's Allergen Specimen Collection Instructions.
Limitations
Allergen-specific IgE concentrations may not correlate with the degree of clinical response. Negative test results do not rule out the possibility of an allergic reaction, including anaphylaxis. It is important to correlate laboratory results with clinical history and in vivo reactivity to specific allergens for an accurate diagnosis.
