When the Food Sensitivity test is ordered twice, the number in parenthesis is the previous result.
If there are no parenthesis (for example, duck, goose, grapevine snail, rabbit and veal in the image above), it means that analyte has only been ordered once. And no previous result is available.
This is possible because Vibrant offers multiple Food Sensitivity testing options -- Profile 1, Profile 2, Vegetarian Profile, and Complete Food Sensitivity -- and the same analytes are always measured both times.
