Regarding allergy testing issues?

Dr.
Jiang: Hello! I would like to ask you about my long-standing allergy issues (approximately 20 years), which have been fluctuating in severity.
I have been relying on medication, but recently the symptoms have worsened.
Previously, a doctor diagnosed me with urticaria, but we have not been able to identify the allergens.
I would like to know if blood tests for allergens are divided into first and second phases, and whether these tests are covered by health insurance or if I need to pay out of pocket.
Additionally, does the size of the hospital or clinic affect the coverage or co-payment amounts? Thank you!

Hello: In response to your question, the cause of urticaria is related to allergic constitution, and routine allergy blood tests may not identify the specific allergens.
Urticaria can be triggered by medications (such as aspirin, sulfonamides, penicillin, etc.), as well as by consuming certain foods like fish, nuts, additives, and dyes.
Additionally, some individuals may experience allergic reactions from exposure to water, cold, heat, physical pressure, sunlight, or vibrations.
Standard allergy blood tests do not cover all potential allergens, and certain tests may not be reimbursed by health insurance.

More Info

Understanding allergy testing is crucial for individuals who have been suffering from allergic reactions, such as urticaria (hives), for an extended period. In your case, where you have experienced symptoms for about 20 years without identifying the specific allergens, it is understandable that you are seeking more definitive answers through testing.

Allergy testing can be broadly categorized into two main types: skin tests and blood tests. Skin tests are often the first line of investigation and can provide immediate results. However, blood tests, such as the ImmunoCAP test, can also be used to measure specific IgE antibodies to various allergens. These tests can help identify potential triggers for your allergic reactions.

Regarding your inquiry about the phases of blood testing, it is important to clarify that the distinction between "first stage" and "second stage" may refer to the different types of tests available or the process of testing for multiple allergens. Typically, an initial panel may test for common allergens, and if those results are inconclusive, further testing may be warranted.
As for the coverage of these tests by health insurance (健保), it can vary based on several factors, including the specific health insurance plan you have, the type of test being conducted, and the healthcare facility where the test is performed. In many cases, basic allergy testing may be covered, but more specialized tests could require out-of-pocket expenses. It is advisable to check with your insurance provider for detailed information regarding coverage and any potential co-pays.

The size and type of the healthcare facility can also influence coverage and costs. Larger hospitals may have different agreements with insurance companies compared to smaller clinics, which can affect the amount you might need to pay out-of-pocket. Therefore, it is beneficial to inquire directly with the facility where you plan to have the tests done to understand their billing practices and whether they accept your insurance.

If you are considering allergy testing, it is essential to consult with an allergist or a healthcare provider who specializes in allergies. They can guide you through the testing process, help interpret the results, and develop a management plan tailored to your specific needs. This may include avoidance strategies for identified allergens, medication management, or even immunotherapy if appropriate.

In summary, allergy testing can provide valuable insights into your condition, and understanding the coverage and procedures involved is crucial for making informed decisions about your healthcare. Be proactive in discussing your concerns with your healthcare provider and insurance company to ensure you receive the best possible care.
