Preparing for a Sheep Allergy Test starts with three questions: whether you need to fast, when to collect, and what to bring. The Sheep Allergy Test is a blood test that checks for an allergic response to sheep epithelium, the tissue material found in sheep wool, dander, and related exposures.
What the results reflect
It measures the level of IgE antibodies directed against sheep epithelium in your blood. Results are generally reported as a numeric value or class that reflects the likelihood and degree of sensitization. Higher results may suggest a greater chance that sheep exposure triggers your symptoms, but they are interpreted alongside your history.
- Sheep epithelium specific IgE
- IgE antibody level
- Sensitization status
Getting ready for the Sheep Allergy Test
Standard preparation is usually all that is needed for this blood test. Confirm any timing or fasting instructions with the collection lab before your visit.
- Confirm with the lab whether fasting is required for this test.
- Stay hydrated by drinking water before your blood draw unless told otherwise.
- Tell the collector about any medications, especially antihistamines, that might affect allergy testing.
- Avoid applying lotions or creams to the arm area if possible.
- Bring a list of your current medications and known allergies to the appointment.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is generally not required for this allergy blood test, but some labs may have their own instructions. Confirm with your lab whether you need to fast.
Best time to collect
This test can usually be collected at any time of day that is convenient. If your clinician wants to compare results with symptom timing, follow their guidance on when to schedule the draw.
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.

The collection visit, step by step
A healthcare professional collects a small blood sample from a vein in your arm using a needle. The sample is then sent to a laboratory for analysis, and the draw itself usually takes only a few minutes.
Details worth confirming with the collection lab before your visit:
- Does this test require fasting or any timing restrictions?
- Which medications should I avoid before the blood draw?
- When and how will I receive my results?
Why a clinician may order this test
A clinician may order this test when you report symptoms such as sneezing, nasal congestion, itchy or watery eyes, or breathing changes after contact with sheep or sheep products. It helps determine whether an allergy to sheep epithelium could be responsible for your symptoms.
Reading your results responsibly
Reference ranges and reporting formats vary by laboratory, so your results should be interpreted using the range provided by the lab that performed the test. A clinician reviews your results together with your symptoms and exposure history to guide next steps.
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.
Common questions
Frequently asked questions
Do I need to fast for the Sheep Allergy Test?
Fasting is usually not required for this blood test, but lab policies can differ. Confirm with your collection lab before the appointment.
How long does it take to get results?
Results are commonly available within one to three business days, though timing can vary by laboratory. Ask your lab for their expected turnaround.
Can medications affect the results?
Some medications, particularly antihistamines, may influence allergy testing. Tell your clinician and the lab about all medications you take before testing.
What does a positive result mean?
A positive result suggests your immune system has produced IgE antibodies to sheep epithelium. Your clinician will interpret this alongside your symptoms and exposure history.
