Allergy testing in Chantilly is $249 — a single blood draw that screens for IgE antibodies to common food and environmental allergens, with no needle-stick skin pricks and no antihistamine washout required. Food Sensitivity Testing is also $249. Both are flat cash prices with results in 24–72 hours; which one is right for you depends on whether you are investigating a true allergy or a delayed food reaction.
There are two different tests here, and they measure different things. A blood allergy panel measures IgE antibodies — the immune pathway behind classic allergic reactions (hives, swelling, itching, anaphylaxis). A food sensitivity panel measures IgG antibodies, which reflect food exposure and may help some people identify foods to trial-eliminate.

Allergy testing vs food sensitivity testing
| Allergy Testing (IgE) | Food Sensitivity (IgG) | |
|---|---|---|
| Price | $249 | $249 |
| Antibody measured | IgE | IgG |
| What it screens for | Food & environmental allergens | Delayed food reactions / exposure |
| Collection | Single blood draw | Single blood draw |
| Results | 24–72 hours | 24–72 hours |
An honest caveat on IgG food-sensitivity testing: major allergy organizations note that IgG antibodies often indicate exposure or tolerance rather than a clinically meaningful sensitivity, so the test is not a validated diagnosis of food intolerance. Many people still find it a useful starting point for a guided elimination diet — but the results should be interpreted with a clinician, not treated as a verdict.
The blood-test format has real advantages over skin-prick testing. There are no needle-stick pricks across your arm or back, and — because the test measures antibodies in a blood sample — you do not need to stop antihistamines beforehand the way skin testing requires. A blood allergy panel screens for sensitization; it is not a diagnosis on its own, and a positive result should be confirmed against your real-world symptoms with a provider.
