Hello: To briefly answer your questions:
1.
Can urticaria be cured? Urticaria can be classified into "acute" urticaria, which typically resolves within a few days to one or two weeks.
If it lasts longer than six weeks, it is referred to as "chronic" urticaria.
"Acute" urticaria can be triggered by (1) foods such as seafood, peanuts, eggs, milk, mangoes, etc.; (2) medications, especially antibiotics, analgesics, gout medications, vitamins, etc.; (3) infections, including chronic dental issues, periodontal disease, sinusitis, urinary tract infections, candidiasis, hepatitis B and C, viral upper respiratory infections, intestinal parasitic infections, scabies, and even Helicobacter pylori infections commonly associated with gastric ulcers; (4) environmental allergens such as pollen, spores, dust, chemical solvents, grass, or trees.
The causes of "chronic" urticaria are more extensive and may include endocrine disorders (thyroid abnormalities), autoimmune diseases, and physical factors such as sunlight, temperature and humidity changes, emotional instability, excessive stress, exercise, and poor water quality.
If the cause is identified and treated accordingly, it can be cured; however, many people's allergens stem from environmental and climatic factors that are difficult to eliminate, requiring long-term medication for management.
2.
Is it possible to test for allergens? If you are certain that you have a food allergy, you can have a blood test to check for elevated levels of Immunoglobulin E (IgE).
If abnormalities are found, further specific antibody allergy testing (MAST allergy test) can be conducted.
However, do not have high expectations, as only 33 common allergens are screened.
It is also common to encounter cases where IgE levels are high, but MAST results are normal.
Paying attention to your exposure history before an outbreak is often more useful.
3.
What are the costs and testing items? The IgE test can be performed in an outpatient setting (blood draw) and is covered by health insurance codes.
It is more accurate to test when symptoms are present; if you have a history of allergies but are not experiencing symptoms during the visit, the test may not be useful, so there is no need to waste your valuable blood.
Many patients visit clinics, but clinic doctors generally do not conduct these tests, likely due to the ease of insurance coverage reductions.
If you have concurrent asthma, angioedema, allergic rhinitis, or conjunctivitis, it is best to test during an outbreak to at least identify allergens and prevent future occurrences.
As for the specific antibody allergy test (MAST allergy test), if elevated IgE levels are found, the doctor can assist with this test.
If IgE levels are normal, requesting a MAST test will not be covered by insurance, so medical facilities will require you to pay out of pocket, with costs ranging from approximately $180 to $200.
To hope for a quick resolution to your urticaria troubles, it is still best to consult your physician for proper treatment.

More Info
Urticaria, commonly known as hives, is a skin condition characterized by itchy, raised welts or bumps on the skin. The question of whether urticaria can be cured is complex and depends on the underlying cause of the condition. In many cases, urticaria is acute and can resolve on its own within a few days to weeks, especially if it is triggered by a specific allergen or irritant. However, chronic urticaria, which lasts for six weeks or longer, can be more challenging to manage and may not have a definitive cure.
The management of urticaria typically involves identifying and avoiding triggers, which can include certain foods, medications, insect stings, or environmental factors. Allergy testing can be a valuable tool in this process. Skin prick tests or blood tests can help identify specific allergens that may be causing the hives. If a specific allergen is identified, avoiding that allergen can significantly reduce or eliminate symptoms.
In terms of costs, allergy testing can vary widely depending on the type of test performed and the healthcare provider. Skin prick tests are generally less expensive than blood tests, but the total cost can also depend on the number of allergens being tested. In the United States, the cost of allergy testing can range from $100 to $1,000, depending on the complexity of the tests and whether or not insurance covers them. It’s essential to check with your insurance provider to understand what is covered under your plan.
As for the testing process, it typically involves a consultation with an allergist or dermatologist who will review your medical history, perform a physical examination, and recommend appropriate tests based on your symptoms. Common tests for urticaria may include:
1. Skin Prick Test: Small amounts of potential allergens are applied to the skin, and the skin is pricked to see if a reaction occurs.
2. Blood Tests: These tests measure specific IgE antibodies in response to allergens.
3. Patch Testing: This is used to identify delayed allergic reactions and involves applying patches with allergens to the skin for a specific period.
4. Provocation Tests: In some cases, controlled exposure to suspected allergens may be conducted under medical supervision.
It’s important to note that while allergy testing can help identify triggers, not all cases of urticaria are related to allergies. Other factors, such as stress, infections, or autoimmune conditions, can also play a role. Therefore, a comprehensive evaluation by a healthcare professional is crucial for effective management.
In conclusion, while urticaria can often be managed effectively, especially when triggers are identified and avoided, the potential for a complete cure may depend on the individual case. If you are experiencing persistent or severe symptoms, it is advisable to consult with a healthcare provider who can guide you through the testing process and develop a tailored treatment plan. Remember, managing urticaria often requires a multifaceted approach, including lifestyle modifications, medication, and possibly allergy testing to achieve the best outcomes.
