Immunoglobulin G (IgG) against bovine serum albumin (BSA) antibody, mass concentration (serum/plasma)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have suspected allergies to cow products, are undergoing allergy testing, or if your immune system’s response to bovine proteins needs evaluation. It could also be part of research or diagnostic studies involving bovine exposure.

What to Expect Before the Test

No special preparation is typically needed. You may provide a blood sample (serum or plasma) during a routine clinic visit. If you’re undergoing allergy testing, your provider may guide you on avoiding bovine products before the test.

What the Test Results Mean

Higher-than-normal levels may indicate an immune response to bovine serum albumin, such as an allergy or autoimmune reaction. Lower-than-normal levels suggest minimal or no antibody presence. Results are interpreted by your healthcare provider in the context of your medical history.

Common Reasons for Testing

This test is less commonly performed in routine clinical practice but may be used in specialized allergy evaluations, research studies, or cases where bovine protein exposure is suspected.
