What are cross reactive carbohydrate determinants?
What are cross reactive carbohydrate determinants?
Cross-reactive carbohydrate determinants (CCDs) play a role in the context of allergy diagnosis. The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects.
What is Indicatorband?
An indicator band on each strip verifies correct performance of the test. Results are evaluated and archived automatically using the EUROLineScan software and issued in standardised EAST classes.
What does indicator mean in allergy test?
A POSITIVE indicator result means that IgG antibodies have been detected against one or more of the foods, indicating that this may be causing your symptoms. If you have a POSITIVE result, you can choose to ”upgrade” from the Indicator test to a 40 , 60 , 120 or 200, vegetarian or vegan food intolerance test.
What is IgE level?
The total IgE test measures the overall quantity of immunoglobulin E in the blood, not the amount of a specific type. It can be used to detect an allergic response in the body rather than a specific allergy. This test may compliment the information provided by allergy tests that detect allergen-specific IgE.
What level is considered an allergy?
Reference range:
Class | kU/L | Levels of Specific IgE |
---|---|---|
0 | < 0.10 | Absent or Undetectable Individual/Component Allergen(s) |
0 | 0.10 – 0.34 | Very Low for Individual/Component Allergen(s) |
I | 0.35 – 0.69 | Low for Individual/Component Allergen(s) |
II | 0.70 – 3.49 | Moderate for Individual/Component Allergen(s) |
What is a Class 5 allergy?
Class 5: Very high level of allergy (50.00 KUA/L – 99.9 KUA/L) indicative of very high level sensitization. Class 6: Very high level of allergy (≥ 100.0 KUA/L) indicative of very high level sensitization.
What is a class three allergy?
Class 3: High level of allergen specific IgE. Class 4: Very high level of allergen specific IgE. Clinical diagnosis of allergies depends on the amount of allergen-specific IgE found and physical symptoms when exposed to that specific allergen.
What is a Class 1 allergy?
Traditional or class 1 food allergens, such as egg, are heat-, enzyme-, and low pH-resistant water-soluble glycoproteins ranging in size from 10 to 70 kD. Class 1 food allergens induce allergic sensitization via the gastrointestinal tract and are responsible for systemic reactions (traditional or class 1 FA)13).
What do you mean by cross reactive carbohydrate?

How are cross-reactive carbohydrate determinants play a role in the diagnosis of Allergy?
] Cross-reactive carbohydrate determinants ( CCDs) play a role in the context of allergy diagnosis. The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects.
Which is a protein-linked carbohydrate determinant?
The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects. In serum-based allergy diagnosis, antibodies of the IgE class directed against CCDs therefore give the impression of polysensitization.
