What this test is
This test measures specific IgE antibodies produced by the immune system in response to clam proteins. It is used to help evaluate whether a person has a shellfish allergy, though results are interpreted alongside a person's history and other findings.
What it measures
- Clam-specific IgE — Reflects the level of antibodies directed against clam proteins.
- Total IgE — Sometimes measured to provide context for allergic tendencies.
- Shellfish panel components — May include other shellfish allergens to check for cross-reactivity.
What the test involves
A small blood sample is collected from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when someone reports symptoms such as hives, swelling, or difficulty breathing after eating clams or other shellfish. It can also help assess the likelihood of a shellfish allergy when the history is unclear.
Preparation
In general, no special preparation is needed for this blood test, but you should follow the specific instructions provided by the collection laboratory. This may include avoiding certain medications or fasting, depending on the lab's protocol.
