β-Lactoglobulin
Use
The β-Lactoglobulin test is used to detect specific IgE antibodies to β-Lactoglobulin, which can indicate an allergic response to proteins found in cow's milk. It is an important diagnostic tool for individuals suspected of having a milk allergy. Understanding IgE levels can help guide dietary management and therapeutic decisions for patients with suspected or known allergies to dairy products.
Special Instructions
The test requires serum collected in a red-top tube or gel-barrier tube. The stability of the sample is optimized when stored at room temperature and should be handled with care to avoid any loss of sample integrity. Testing schedules may vary, and it is advised to contact Labcorp for specific scheduling or additional confirmatory testing requirements.
Limitations
This test specifically measures IgE antibodies against β-Lactoglobulin and may not encompass all allergenic proteins present in cow's milk. Negative results do not rule out dairy allergy due to potential allergenic proteins not covered by this test. The test should be part of a comprehensive assessment that includes clinical history and other diagnostic procedures. False positives or negatives may occur.
