Plum (f255)0855
Plum is a stone fruit tree from the genus Prunus of the Rosaceae family. Plums are widely used as dessert fruits, eaten fresh, added to baked goods and preserves. Dried fruit – prunes – are especially popular, known for their laxative properties.
The main allergenic components of plum are identified: Pru d1 (Bet v1 homolog), Pru d2 (thaumatin-like protein), Pru d3 (9 kDa lipid transfer protein), Pru d4 (profilin). The lipid transfer protein Pru d3, concentrated in the fruit skin, is particularly important as it causes cross-reactivity with other fruits of the Rosaceae family (peach, apricot, cherry, apple). Cross-reactivity may not be accompanied by clinical allergy, so it is important to avoid unnecessary dietary restrictions. Plum allergy may also be associated with birch pollen and latex allergy.
- Diagnosis of allergic reactions to plum.
- Assessment of sensitization level and risk of allergy development.
- Monitoring therapy effectiveness.
- Evaluation of sensitization level after allergen avoidance.
- Assessment of immune system status.
FEIA (Fluorescence Enzyme Immunoassay, ImmunoCAP (Solid-phase Immunofluorescence)) – quantitative determination.
