What is the Perennial Allergy Testing Year Round?
The Perennial Allergy Testing Year Round is an allergen-specific IgE blood test that measures whether your immune system has produced antibodies targeting perennial.
This IgE allergy test panel checks for 19 of the most common perennial allergens that can affect individuals year-round. Popular allergy tests: Cat, dog, molds,.
How the Perennial Allergy Testing Year Round works
A small blood sample is analyzed with an immunoassay that measures allergen-specific IgE antibodies — the immune proteins your body produces in response to substances it has become sensitized to. Unlike skin-prick testing, a single blood draw covers many allergens at once, with no needles in the skin and no antihistamine restrictions beforehand.

Why healthcare providers order it
Healthcare providers order the Perennial Allergy Testing Year Round providers order allergen-specific IgE testing when someone experiences allergy-type symptoms — sneezing, congestion, itchy/watery eyes, hives, eczema flares, digestive upset after foods, or wheezing — and wants to identify which specific triggers are involved. Results help target avoidance strategies and inform whether allergy referral or treatment is warranted.
Interpreting your results
Understanding allergen-specific IgE results
Results are reported as a concentration of allergen-specific IgE antibodies and assigned a class:
- Class 0 — Negative: no detectable specific IgE. Sensitivity to this allergen is unlikely, though rare non-IgE reactions exist.
- Class I — Low/Equivocal: borderline sensitization. May be clinically meaningful if symptoms clearly track with exposure.
- Classes II–III — Moderate: convincing sensitization; correlation with your symptom history is strong.
- Classes IV–VI — High to Very High: strong sensitization, generally consistent with clinical allergy when symptoms align.
Key caveat: a positive IgE result shows sensitization, not guaranteed clinical allergy. Some sensitized people never react on exposure. Diagnosis rests on matching lab results to your actual symptom history — ideally with a board-certified allergist. A negative result makes IgE-mediated allergy unlikely but does not explain away symptoms on its own.
What your allergy result means
Reference intervals vary by laboratory, instrument, age, sex, and — for hormones — collection time. Always compare your value against the range printed on your own report, and review results with a qualified healthcare professional who knows your history. This guide is educational and does not diagnose.
Understanding your lab report
- Find the reference interval printed beside your value on the report — that pairing defines 'normal' for this lab run.
- Preparation affected this sample: Follow the lab's instructions. — mention deviations from instructions when reviewing results.
- Note the units. mmol/L vs mg/dL, ng/mL vs µg/L — numbers mean nothing across unit systems.
- Look at flags (H/L) but read the degree: barely-outside values behave differently than multiples of the limit.
- Trends outrank snapshots. A series of results tells your provider far more than any single draw.

Frequently asked questions
What does the Perennial Allergy Testing Year Round measure?
It measures allergen-specific IgE antibodies — immune proteins produced in response to perennial included in this panel.
Do I need to prepare for the Perennial Allergy Testing Year Round?
Follow the lab's instructions. When in doubt, ask the drawing laboratory — preparation errors are a leading avoidable cause of unusable results.
How soon do Perennial Allergy Testing Year Round results come back?
This test's typical turnaround is 1-3 business days, counted from the laboratory's receipt of your sample. Complex or send-out assays can take longer.
Can an abnormal Perennial Allergy Testing Year Round result mean something serious?
A positive result shows sensitization, not a guaranteed reaction — severity comes from your symptom history, not the number alone. A negative result makes IgE-mediated allergy unlikely.
Does a positive Perennial Allergy Testing Year Round mean I will definitely react?
No — positivity shows sensitization (IgE present). Clinical allergy requires symptoms on actual exposure. Allergists weigh both together, and sometimes recommend supervised oral challenges before imposing lifelong avoidance.
