Description

What are CCDs?

CCDs, or Cross-reactive Carbohydrate Determinants, are sugar molecules on many proteins that can cause false positives in allergy tests by reacting with IgE antibodies, even in the absence of a true allergy.

How do CCDs affect allergy testing?

CCDs can lead to misleading allergy test results, showing sensitivities where none may exist. Recognizing and accounting for CCD reactions is essential for accurate allergy diagnosis.

Acknowledging CCDs helps avoid unnecessary dietary restrictions and anxiety by clarifying which test results indicate real allergies and which are due to these carbohydrate determinants.

Can you avoid false positives caused by CCDs in tests?

Yes, by using specific diagnostic approaches that distinguish between true allergens and CCDs, healthcare providers can minimize false positives, providing a clearer understanding of a patient’s allergies.

Are CCD reactions the same as allergic reactions?

No, reactions to CCDs are not true allergic reactions to specific proteins but rather to the carbohydrate structures, not causing typical allergy symptoms.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the USA. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
