Thistle, Russian
Also known as: Russian Thistle
Use
The Thistle, Russian test is used to measure the levels of specific IgE antibodies to Russian Thistle allergens in the patient's serum. This test helps in diagnosing allergic conditions related to Russian Thistle exposure and determining the patient's sensitivity to this specific allergen. High levels of specific IgE antibodies indicate an allergic sensitization to Russian Thistle.
Special Instructions
Ensure the serum sample is collected in a red-top or gel-barrier tube and stored appropriately as per the stability requirements to maintain the integrity of the specimen. Testing schedules may vary, and additional time may be required for confirmatory or reflex tests.
Limitations
This test is specific to IgE antibodies against Russian Thistle allergens and may not detect all possible allergens affecting the patient. False negatives can occur, and results should be interpreted in the context of clinical symptoms and history. Cross-reactivity with other allergens may also occur. It is important to allow for potential discrepancies due to sampling, handling, and processing.
