IgE testing, also known as allergy blood testing, including the serum ige test s important for a variety of reasons, especially when you are managing an autoimmune condition, allergies, or other medical issues related to allergen exposure. You can get a precise IgE reading by getting a blood test done to compare against normal IgE levels.
Immunoglobulin E or immunoglobulin e ige is an antibody released by the immune system in response to an infection or a potential threat, which can indicate an allergic response. By measuring the levels of IgE in the body, doctors can get a better understanding of whether you have an allergic reaction or an underlying autoimmune condition.
Your serum IgE levels are checked in an Immunoglobulin E blood test, which involves B cells, and the serum IgE test results will gauge whether there is an infection or an underlying condition that is causing an immune reaction, based on your blood test. The serum total IgE levels need to be checked if you are observing symptoms of allergic bronchopulmonary aspergillosis and experiencing symptoms of elevated IgE for extended periods. This blood test also detects the presence of any allergic disease in the body. However, proper medications generates IgE antibodies in the body.
Your total serum IgE levels can also help doctors know the total ige test result, including specific ige, and whether there is an underlying medical condition that requires intervention. Allergic asthma, allergic conjunctivitis and other allergic diseases can be checked with total IgE testing, which is why it is vital in many cases.
When you receive your total IgE levels report, you may want to know more about your test results, especially concerning certain foods and what they indicate.
Higher levels of total IgE can indicate the presence of high levels of asthma, stuffy nose, sneezing, allergic rhinitis, atopic dermatitis, and other conditions resulting from a hypersensitivity reaction. These could be causing a direct elevation in the total IgE serum test, such as asthma, chronic rhinosinusitis.
Your normal levels of IgE antibodies or total IgE indicate a normal condition when it comes to allergy-specific IgE testing. If you have experienced an allergic reaction, such as hay fever, then your IgE levels will not be normal.
Lower IgE levels can indicate the presence of chronic fatigue, autoimmune and other conditions. You should get further testing done to know the true cause.
These are the normal IgE levels by age and can often be verified at a diagnostic center. They may differ depending on multiple factors, including the patient's presentation, which is why the test will depend on your complete medical profile.
0 − 15 IU/mL)
0 − 60 IU/mL.
0 − 90 IU/mL.
In an older child, the specific IgE range can be 0 − 200 IU/mL.
0 − 100 IU/mL.
There are multiple instances wherein an IgE test should be performed for individuals for accurate diagnosis . Some of the main ones are mentioned below.
If you have immune health issues, then getting an IgE test done will be key. You can get a complete breakdown of what your levels are and what your risk factors are based on your reading from the test tube.
If you have signs of serious infection, then your IgE levels will be elevated. It is important to track the progression of the infection like hypersensitivity reaction, food allergies, or any other symptoms through the IgE levels test, especially when levels are extremely high. If any irritation like eye inflammation continues foe less than five minutes, there's nothing to worry. Otherwise, for several symptoms, you must consult a doctor.
If you have intolerances and food allergies, then getting regular IgE testing, which measures histamine responses, will be key. This will help you understand your risk profile in terms of common allergens found in the environment and avoid a life threatening allergic reaction .
If you have a prior history of an allergy asthma, allergic disease, or hyper IgE syndrome, then getting immunoglobulin IgE testing done regularly to monitor for specific allergens will be important. You should present your entire medical history, particularly regarding mast cells, prior to getting tested.
