- Stay hydrated and drink water before your blood draw unless told otherwise.

Fasting, timing, sample type, and what to bring
Fasting
Fasting is generally not required for this test, but some labs may have specific instructions. Confirm with your lab.
Best time to collect
The sample can usually be collected at any time of day. If you take antihistamines, ask the lab whether timing around your dose matters.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- 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
- Your order confirmation email, in case the collection site asks to see it
- A written list of the medications and supplements you currently take
- 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)
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.
At the collection site
A healthcare professional collects a small blood sample from a vein in your arm using a needle. The sample is sent to a laboratory for analysis, and the draw usually takes only a few minutes.
Details worth confirming with the collection lab before your visit:
- Do I need to fast before this test?
- Should I pause any antihistamines or medications before the draw?
- When can I expect my results?
When this test is useful
A clinician may order this test when you have allergy symptoms that could be related to hackberry tree pollen, such as sneezing, congestion, or itchy eyes. It helps confirm sensitization and guide avoidance or treatment discussions.
Reading your results responsibly
