Herring F205

The Herring F205 test is a specialized test used to diagnose an allergy to herring, a fish rich in vitamin D, long-chain polyunsaturated fatty acids, and calcium. The test is conducted at IntroLab in Belgrade, where a blood sample is taken for analysis.

Why is the Herring F205 test important?

Herring is commonly consumed in various forms—salted, pickled, smoked, or canned. Fish allergies, including those to herring, are more prevalent in countries with a well-developed fishing industry.

Symptoms of a herring allergy

Symptoms can range from mild to severe and may include:

• Respiratory issues such as asthma and frequent sneezing
• Skin reactions like allergic contact dermatitis
• In some cases, anaphylactic shock, which requires immediate medical attention

How is the test performed?

A blood sample, typically drawn from a vein, is collected to extract serum for analysis.

What does the Herring F205 test show?

The main allergen in herring is Beta-parvalbumin (Clu h 1), a protein found in the fish’s muscles. This test identifies antibodies to this allergen and may also reveal cross-reactivity with other fish species, such as sardines.

Risk and prevention

Individuals allergic to herring should avoid consuming this fish. Additionally, those taking antacids (medications to neutralize stomach acid) may be at a higher risk of experiencing more severe allergy symptoms.

The Herring F205 test is a reliable way to diagnose a herring allergy. If you suspect an allergy, this test can provide important information to help you manage your symptoms and prevent potentially serious reactions.
