At SkinDC, we offer the NAC-80 North American 80 Comprehensive Series. The series consists of 80 of the top allergens that may cause an individual to develop contact dermatitis.
Contact Dermatitis – Direct Contact with an Allergen
These are so-called cell-mediated immunity, also called Type 4 allergies (delayed hypersensitivity). The hapten (allergen) that trigger symptoms are often simple chemicals. The most common disease caused by contact allergy is contact allergic dermatitis.
Other common causes of allergic contact dermatitis are substances in:
Certain drugs for topical use
Contact allergy cannot be cured but is something you will have to learn to live with.
A number of patch tests with different substances will be taped on your back (the number depends on the physician’s choice). Each patch test accommodates 10 potential allergic substances.
A base line series with the most common allergy-causing substances is usually always tested. Additional substances can be added depending on what you and your doctor has come up with before.
For how long do I have these patch tests on me?
The patch tests will be removed after about 2 days, and a first reading can be made 20-30 minutes after removal, if test patches are removed at the clinic.
If you get a very strong reaction with strong itching and redness in any of the test patches, contact your doctor, who may then decide whether you should stop and remove the patch test. Your doctor will inform you if further readings are required within the next 5 to 7 days.
What should I consider during test time?
Keep the test area on the back dry during this time period and avoid heavy and physical exercises that can cause excessive sweating as this may lead to the patch tests coming off.
Cortisone creams and antihistamines should not be used during the entire test period.
Avoid sunbathing on the test area.
The recommendation is also that you should wear loose clothing and sleep in a t-shirt as this helps to prevent the patch tests from rubing or peeling off the skin.
The patch test is getting loose, what should I do?
Have someone press on the test patches. If necessary, you can also reinforce them with additional tape on the edges of the test units.
What should I do if I itch during the patch test?
Try not to scratch at the test site, because the itching is usually a sign of a positive reaction and the itching can alter the test results.
What are the benefits of knowing what I’m allergic to?
Your doctor will tell you what you are allergic to, including where and in what types of products the substance can be found, and how you do to avoid the substance in the future. You will also get you an information sheet.
It turned out that I was not allergic to any of the tested substances, what do I do now?
Negative results are very common. If the test is negative, this is also important information, you will not need to avoid the topics you now tested.
However, there are many more substances that can cause your symptoms. Some patients need to do further testing to determine if they are allergic to these substances.
Your doctor can also determine whether your symptoms are due to an irritation reaction, and then tell you about how to better take care of your skin and avoid irritating substances. If your doctor determines that your skin reaction is due to anything other than a contact allergy, you may be referred to a specialist for further tests and treatment.
Quick check in (especially as a new patient). Office ran on time, and appointment timing was on schedule. I was in/out in a timely manner, but I did not feel rushed by the doctor or the nursing staff. I was pleased with my initial visit.
