Quick answer
The silkworm silk allergy test is a blood test that measures immunoglobulin E antibodies against proteins found in silk produced by the silkworm. Silk from the Bombyx mori moth is used in textiles, and exposure to silk dust or fibers can trigger respiratory, nasal, or skin symptoms in some people. The test helps assess sensitization in those with occupational or household exposure. A healthcare provider interprets the result with the history.
What this test measures
Silk is produced by the larvae of the silkworm moth, Bombyx mori, and proteins from the cocoon can act as allergens. People involved in sericulture, textile manufacturing, or handling silk products may inhale silk dust or come into contact with fibers. Reported symptoms include sneezing, a runny nose, itchy eyes, cough, and asthma-like breathing changes. Reactions are more likely with ongoing exposure.
The test measures allergen-specific IgE in a serum sample and reports a level or reactivity class for silk proteins. Silk allergens can overlap with those of other insects and mites, so results are often reviewed alongside related tests when a broader evaluation is done.
A positive result shows sensitization, which may or may not produce symptoms. Occupational allergy assessment usually combines the blood test with a detailed work history and symptom pattern. A qualified healthcare provider, sometimes with input from occupational health specialists, interprets the findings and discusses options.
- Silkworm silk-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for silkworm silk
- Silkworm larva and cocoon allergens when included
- Cross-reactive insect and mite allergens when available
Why people order this test
- Investigate respiratory symptoms in textile or sericulture work
- Assess occupational exposure to silk dust
- Evaluate nasal or skin symptoms after handling silk products
- Support a work-related allergy evaluation
- Provide objective data before discussing workplace measures with a provider
How to prepare
No fasting is required for this blood test. A sample is collected from a vein, typically at the arm. Follow any instructions provided by the laboratory.
Understanding your results
Results are generally reported within one to three business days. The report shows the silk-specific IgE level or class. An elevated value suggests sensitization, and a healthcare provider interprets it with the individual's exposure and symptoms.

Frequently Asked Questions
What is silkworm silk?
It is a natural fiber produced by the larvae of the silkworm moth, Bombyx mori. Proteins in the silk can act as allergens for some people.
Who is at risk of silk allergy?
People who work in sericulture, textile production, or other settings with frequent silk exposure may be more likely to develop sensitization.
How is the test performed?
A small blood sample is drawn from a vein and analyzed for IgE antibodies that react to silk proteins.
Do I need to fast?
No fasting is required for this test unless it is bundled with other tests that require it.
Can silk allergy be related to other insect allergies?
Yes. Silk allergens can share features with other insect and mite allergens, so results are sometimes reviewed with related tests.
