LKM antibodies
The Lemon IgG test is a laboratory examination that measures IgG antibodies specific to lemon in a patient's serum. IgG antibodies are proteins produced by the immune system in response to foreign substances. The presence of these antibodies indicates sensitization to lemon but does not confirm a food allergy. The test is primarily used in clinical situations where patients have food-related complaints, aiding in dietary elimination and challenge evaluations. Blood is drawn into a red-top or serum gel tube, centrifuged, and 0.5 mL of serum is analyzed using an enzyme immunoassay (FEIA). Results are reported in micrograms per milliliter, with a turnaround time of approximately three business days. While the test provides insights into immunologic sensitization, it should be interpreted cautiously and alongside other diagnostic methods, such as skin prick tests or oral food challenges, to confirm a food allergy diagnosis.

The Lemon IgG test measures IgG antibodies specific to lemon in serum, indicating sensitization but not confirming a food allergy. Its clinical utility is limited, primarily aiding in dietary evaluations. The procedure involves:
- Collecting blood in a red-top or serum gel tube
- Centrifuging and aliquoting 0.5 mL serum
- Using enzyme immunoassay (FEIA) for analysis
Results are reported in mcg/mL, with:
- Negative: No detectable IgG
- Positive: Indicates sensitization
Interpret cautiously, alongside other diagnostic methods, for accurate allergy assessment.
The Liver-Kidney Microsome (LKM) antibody test is essential for diagnosing liver diseases of unknown origin, especially autoimmune hepatitis type 2 (AIH-2). It is particularly useful for:
- Children and Young Adults: Predominantly affects females under 18.
- Suspected Autoimmune Hepatitis: Helps differentiate AIH-2 from other liver diseases.
- Chronic Liver Disease: Evaluates unexplained liver dysfunction.
The test uses IFA or ELISA methods to detect LKM antibodies, with positive results suggesting AIH-2. However, results should be interpreted alongside other clinical findings due to potential false positives in chronic hepatitis C cases.
Understanding test results is crucial for interpreting the Lemon IgG test. This test measures IgG antibodies specific to lemon, indicating sensitization but not confirming a food allergy. Key points include:
- Negative Result: No detectable IgG antibodies.
- Positive Result: Presence of IgG antibodies suggests sensitization.
- Interpretation: IgG presence indicates potential sensitization, not a confirmed allergy.
The test aids in dietary evaluations and immunotherapy preparation but should be used alongside other diagnostic methods for accurate allergy diagnosis.
