Allergen, Food, Mackerel
Also known as: MACKEREL
Use
This test is used to quantitatively measure the level of IgE antibodies to mackerel in the serum of patients. The presence of these antibodies is used to assess potential allergic responses to mackerel consumption. It aids in the diagnosis of food allergies specifically related to mackerel by detecting allergen-specific IgE concentrations which may correlate with hypersensitivity reactions.
Special Instructions
Not provided.
Limitations
This test may not fully correlate with clinical response or skin testing results. Concentrations of allergen-specific IgE detected in this test may not directly correlate with the severity of allergic reactions. A negative result does not rule out the possibility of an allergenic or anaphylactic response. Allergen results in the 0.10-0.34 kU/L range have undetermined clinical relevance and should be evaluated by a specialist in conjunction with the patient’s clinical history and in vivo reactivity.
