The chymopapain (Chymodiactin) allergy test is a blood test that checks for antibodies your immune system may make against chymopapain, an enzyme once used in a back procedure called chemonucleolysis. It is ordered before possible exposure to chymopapain to help identify people at risk of an allergic reaction.
What it measures
- Chymopapain-specific IgE antibody — An antibody type linked to immediate allergic reactions.
- Total IgE — A general measure of allergic antibody levels in the blood.
- Antibody binding signal — How strongly your sample reacts to chymopapain in the lab.
- Control comparisons — Lab checks that help confirm the test worked correctly.
Who it is for
A clinician may order this test before a procedure that uses chymopapain, or when evaluating a past reaction to it. It is not a routine screening test for most people.
Preparation
No fasting is usually required. Tell your clinician about all medicines, especially antihistamines, because some can affect allergy test results.
Results and what they mean
Results are reported as a level or as negative, equivocal, or positive, depending on the lab. A clinician interprets the result alongside your history and other findings; a positive result does not always mean a reaction will occur. This is general information, not medical advice.
