Fasting, timing, sample type, and what to bring
Fasting
Fasting is usually not needed for this IgE test; confirm with your lab.
Best time to collect
The draw can be done any time, though tree pollen tests are often done around your spring symptom season for a clearer picture.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What happens during the collection visit
A small blood sample is drawn from a vein in your arm in about a minute. The lab then measures IgE against white ash pollen.
Details worth confirming with the collection lab before your visit:
- Ask whether fasting applies.
- Ask when results are ready.
- Ask if medicines affect the result.
Why a clinician may order this test
It is ordered when tree pollen season brings on sneezing, itchy eyes, or congestion. It may be part of a tree or seasonal allergy panel.
Your results and next steps
Results come back as an antibody level with ranges that vary by lab. Your clinician reads it with your symptom timing, since a positive test alone does not confirm a clinical allergy.
