Crab

This test measures the level of specific antibodies in your blood that react to proteins found in crab. It helps show if your immune system recognizes crab as a harmful substance, which is useful for investigating symptoms like hives or swelling after eating seafood. This measurement helps distinguish a potential crab allergy from other food sensitivities or reactions to different shellfish. However, this test cannot predict the severity of a future reaction or confirm a diagnosis without a doctor reviewing your medical history.
