Also reported in: IU/mL
Your food-specific IgE is in the normal range. No IgE-mediated allergy to this food is detected.
No specific IgE antibody to this food allergen was detected (Class 0). A negative result makes an IgE-mediated (immediate-type) allergy to this specific food unlikely, though non-IgE-mediated food sensitivities are not excluded by this test.
No action needed for this allergen. A negative result does not exclude non-IgE food sensitivities (FPIES, delayed reactions, food intolerances).
Food specific IgE: Class 0 — negative; no detectable IgE to this food allergenYour specific IgE for this food is negative. This result indicates no significant IgE-mediated sensitization to this specific food allergen.
No action needed for this specific food allergen.
Food specific IgE: Class 0 — negative; no clinically significant sensitizationYour specific IgE is at a very low negative level. No clinically relevant sensitization to this food allergen is detected.
No action needed.
Food specific IgE: very low — no clinically relevant sensitizationYour food-specific IgE is in the normal range. No IgE-mediated allergy to this food is detected.
No specific action required.
Food specific IgE: Class 0 — negative; no IgE-mediated food allergy detectedYour food-specific IgE is in the optimal range with no detectable food allergen sensitization. This is the best possible result.
No action needed.
Food specific IgE: optimal negative — no food allergen sensitizationYour food-specific IgE is in Class 1 (borderline range). This equivocal result indicates low-level sensitization to this food allergen. Class 1 results do not reliably predict clinical allergic reactions and require clinical correlation with your allergy history. Many sensitized individuals tolerate the food without symptoms.
Discuss with your allergist. Oral food challenge under medical supervision may be needed to determine clinical relevance. Do not eliminate foods based on borderline IgE alone without allergy specialist guidance.
Food specific IgE: Class 1 (0.35–0.7 kU/L) — borderline; equivocal sensitization; clinical correlation essentialYour food-specific IgE is in the positive Class 2–4 range, confirming IgE-mediated sensitization to this food allergen. Positive specific IgE indicates sensitization, but clinical allergy (symptoms upon exposure) must be confirmed by your history and potentially an oral food challenge. Higher classes generally correlate with greater likelihood of clinical reaction.
Discuss with your allergist. Clinical history review and possibly supervised oral food challenge are needed to confirm clinical allergy. Your allergist will advise on elimination and emergency epinephrine auto-injector prescription if indicated.
Food specific IgE: Class 2–4 (>0.7 kU/L) — positive; IgE-mediated sensitization confirmedYour food-specific IgE is in Class 5–6, indicating very high-level sensitization with a substantially elevated probability of clinical allergic reaction including anaphylaxis upon exposure to this food. Class 5–6 results are considered consistent with clinical food allergy in the right clinical context for certain foods (peanut, tree nuts, shellfish).
Discuss urgently with your allergist. Strict avoidance of this food is likely required. An emergency epinephrine auto-injector (EpiPen) should be prescribed and you should be trained to use it. Oral immunotherapy may be an option to discuss with your specialist.
