Bean Lima (Phaseolus limensis) IgE
Use
The Bean Lima IgE test is used to measure the levels of IgE antibodies specific to the lima bean allergen in a patient's serum. This test aids in the diagnosis of allergic reactions to lima beans, which is helpful for individuals suspected to have food allergies related to this specific legume. Elevated levels of IgE specific to lima beans can confirm sensitization, which may corroborate clinical observations of allergic response upon consumption.
Special Instructions
Ensure the specimen is drawn and handled as per the collection instructions to avoid compromising the test results. It's important to refrigerate the serum sample in a plastic vial after collection to maintain stability and ensure accurate results. The use of serum gel tubes is acceptable if necessary.
Limitations
The Bean Lima IgE test specifically detects IgE antibodies that react to the lima bean proteins. It cannot assess non-IgE-mediated allergic reactions. Additionally, IgE levels can fluctuate over time and may not directly correlate with the severity of allergic reactions. Cross-reactivity with proteins from related legumes may occur, potentially affecting the specificity of the results. It is important to interpret results in the context of clinical evaluation and consider them as part of a comprehensive allergy assessment.
