Why might someone need this test?
This test is particularly useful in situations where skin allergy tests might not be suitable, such as when someone has extensive skin conditions, has recently taken antihistamines, is uncooperative, or has a medical history indicating a high risk of severe allergic reactions from skin testing.
Understanding Your Results:
A positive result means there's a sensitivity to sheep milk, but it doesn't necessarily mean you'll experience allergic symptoms when consuming sheep milk. Not all sensitivities lead to physical reactions, and a thorough evaluation by a healthcare provider is essential to confirm a food allergy. This test identifies sensitization to sheep milk, which is a step towards understanding your body's reactions but is not a standalone diagnostic tool.
What type of sample is required for this test?
0.3 mL serum.
