This page explains how to prepare for a Dill Allergy Test, what the test measures, and what to confirm with the collection lab. The Dill Allergy Test is a blood test that checks for an allergic response to dill, a common culinary herb.
What the Dill Allergy Test measures
The test measures the level of dill-specific IgE antibodies in your blood. Elevated levels can suggest sensitization to dill, which your clinician interprets together with your symptoms and exposure history.
- Dill-specific IgE
- Total IgE (if included)
- Sensitization status
How to prepare for the Dill Allergy Test
In most cases no special preparation is needed for this test. Ask the testing location about any timing or fasting instructions before your visit.
- Confirm with the lab whether fasting is required for your visit.
- Stay hydrated by drinking water before your appointment unless told otherwise.
- Tell the collector about any medications, supplements, or recent allergic reactions.
- Wear a short-sleeved or loose-fitting shirt to allow easy access to your arm.
- Arrive with time to spare so the collection is not rushed.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is usually not required for this allergy blood test, but some locations may have their own rules, so confirm with your lab.
Best time to collect
This test can generally be collected at any time of day. If you are also having other tests done at the same visit, follow the timing instructions given for those tests.
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
- 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
- A short-sleeved or loose-sleeved shirt for an easy blood draw
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.

What the collection involves
A trained collector draws a small sample of blood from a vein in your arm, usually in less than a few minutes. The sample is then sent to a laboratory for analysis, and you can typically resume normal activities right away.
Details worth confirming with the collection lab before your visit:
- Does this test require fasting or any timing restrictions?
- When should I expect the results to be available?
- Should I stop any medications or supplements before the draw?
When this test is useful
A clinician may order this test when you report symptoms such as hives, itching, swelling, or digestive upset after eating dill or foods containing it. It helps clarify whether dill is a likely trigger and guides decisions about avoidance and further evaluation.
What results mean
Reference ranges and reporting formats vary between laboratories, so results should always be interpreted using the range provided by the testing lab. Your clinician will combine the result with your symptom history to decide what it means for you.
General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov), and is reviewed for clarity. Preparation and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. Preparation instructions, timing, and pricing vary by collection lab — always confirm them with the lab that will perform your draw.
