About the allergen in Japanese cedar
The allergen in Japanese cedar is usually a protein called Cry j 1. It is one of several proteins found in Japanese cedar pollen and is a common cause of allergic reactions in people who are allergic to pollen.
When a person allergic to Cry j 1 is exposed to Japanese cedar pollen, the immune system responds by producing antibodies against the protein. This can lead to allergic symptoms such as sneezing, runny nose, itchy eyes, and asthmatic symptoms.
How can I find out if I am allergic to Japanese cedar?
A blood test can be used to investigate an allergy to Japanese cedar by measuring the levels of specific antibodies in the blood that are associated with allergic reactions to Japanese cedar. The test is called a specific IgE test.
The results of the test will show whether or not you have an allergic reaction to Japanese cedar. If the levels of specific IgE antibodies are high, it may indicate that you are allergic to Japanese cedar.
It is important to note that the result of an IgE test does not always correlate completely with symptoms of allergy, and that the test is only part of the investigation process.
If you take a Japanese cedar allergy test and your IgE antibodies are found to be elevated, you can show your result to a doctor or allergy specialist who can help you with a full assessment and possible treatment.
