Below is a plain-language prep guide for the swordfish allergy test in Highland Acres, DE, including sample type and timing basics. The Swordfish Allergy Test is a blood test that checks whether your immune system reacts to swordfish, a commonly eaten fish.
What this test looks at
The test measures the level of IgE antibodies in your blood that are specific to swordfish. The reported value reflects how strongly your immune system recognizes swordfish proteins. Your clinician interprets that number alongside your symptoms and history.
- Swordfish-specific IgE
- IgE antibody response
- Allergen reactivity
How to prepare for the Swordfish Allergy Test
Expect little to no preparation for this test. Confirm timing or fasting details with the collection site when you schedule your appointment.
- Confirm with the collection site whether any fasting is required for your visit.
- Drink water beforehand to make the blood draw easier.
- Take your regular medications unless the lab or your clinician tells you otherwise.
- Tell the collector about any antihistamines, steroids, or allergy medications you take.
- Bring your test order and photo identification to the appointment.
- Avoid applying lotion or cream to the arm area before the draw if possible.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is generally not required for this test, but some collection sites or clinicians may request it depending on other tests ordered at the same visit, so confirm with your lab.
Best time to collect
This test can usually be collected at any time of day. If your clinician ordered other tests alongside it, follow the timing instructions given for the full panel.
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 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.
The collection visit, step by step
A phlebotomist cleans the skin, typically on the inside of your elbow, and inserts a small needle into a vein. Blood is collected into a tube or tubes, the needle is removed, and a bandage is applied.
Details worth confirming with the collection lab before your visit:
- Does this test require fasting?
- Should I pause any allergy medications before the draw?
- When and how will I receive my results?
When this test is useful
A clinician orders this test when a person reports symptoms such as hives, swelling, or digestive upset after eating swordfish. It helps clarify whether swordfish is a likely trigger and guides further allergy evaluation.
Reading your results responsibly
Results are typically available within one to three business days. Reference ranges and reporting units vary by laboratory, so your result should be interpreted using the range printed on your own report.

Highland Acres has multiple collection options, and the preparation steps above stay the same wherever you go. Confirm the site's hours, ID requirements, and payment policy first.

Do I need to fast for a swordfish allergy test?
Fasting is usually not necessary, but requirements can vary if other tests are ordered at the same time. Confirm with your collection lab before your appointment.
Can I take my allergy medication before the test?
Some medications can influence allergy testing, so ask your clinician or the lab whether anything should be paused and for how long.
