See http://www.phadia.com/Products/Allergy-testing-products/ImmunoCAP-Allergen-Information/Food-of-Plant-Origin/Seeds–Nuts/Sugar-beet-seed-/. Is the W210 allergen still available? The w210 page appears to point to f227. Are these different or has phadia merged the two and are now the same? Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
