What this test is

The Silkworm Silk Allergy Test measures specific IgE antibodies in the blood that react to proteins found in silkworm silk, typically from the Bombyx mori species. It helps identify sensitization to silk allergens, which may be relevant for people with occupational exposure.

What it measures

What the test involves

Why it is often ordered
