A Codfish Allergy Test in Riverview, SC is usually quick, and most of the work is in the preparation: timing, fasting, and a short checklist. The Codfish Allergy Test is a blood test that checks for an allergic sensitization to codfish.
What the results reflect
It looks for codfish-specific IgE in the blood. The result helps a clinician decide whether cod may be behind your symptoms.
- Codfish-specific IgE
- IgE antibody level
- Sensitization status

Fasting, timing, sample type, and what to bring
Fasting
Fasting is not normally required for this IgE test; confirm with your lab.
Best time to collect
The draw can happen at any hour. An early appointment can help the lab return results sooner.
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.
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 collector draws a small blood sample from your arm, and the process takes only a couple of minutes. The sample is shipped to a lab for cod-specific IgE testing.
Details worth confirming with the collection lab before your visit:
- Ask if fasting is needed.
- Ask how soon results return.
- Ask whether your medications matter.
Why a clinician may order this test
It is ordered when eating cod or other fish brings on hives, swelling, or digestive upset. It can also be included in a fish allergy panel.
Understanding your results
Results are given as an antibody level with reference ranges that differ by lab. Your clinician pairs the number with your history, since a positive test does not always mean a clinical allergy.
