Understanding Lab Tests for Fig Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A fig allergy occurs when the immune system mistakenly identifies proteins in figs as harmful substances, triggering an allergic reaction. Symptoms can range from mild skin reactions to severe anaphylaxis. Accurate diagnosis through blood testing is essential for proper management and avoidance strategies.
Recommended Test
Fig (Ficus carica) (f328) IgE
This test measures the level of IgE antibodies specifically produced against fig proteins in your blood. Elevated levels indicate that your immune system has identified fig proteins as allergens and produces antibodies against them. This immune response can trigger allergic symptoms ranging from mild reactions like itching, swelling, and hives to severe complications including difficulty breathing and anaphylaxis.

Diagnosing Fig Allergy
While symptoms may suggest a fig allergy, definitive diagnosis requires specific testing to measure the immune system's response to fig proteins. This testing helps distinguish a true allergy from food intolerance or other conditions with similar symptoms.
Understanding Your Results
A positive result indicates the presence of fig-specific IgE antibodies, confirming an allergic sensitivity to figs. Higher levels typically correlate with increased likelihood of experiencing allergic reactions upon fig consumption. Your healthcare provider will interpret these results alongside your clinical symptoms to develop an appropriate management plan.
