This is correct. A specialist told me that there may be no correlation whatsoever between the test results and what the test subject will or won't react to in the real world. I've had food allergy/sensitivity tests done for both Saoirse and my civvie, Lúnasa. I got the tests done (IIRC by IDEXX, not Nutriscan) because both of my girls had significant GI issues (chronic pancreatitis/suspected IBD in Saoirse's case, and Lúnasa had undiagnosed hyperthyroidism at the time the test was performed).
I know from the litter box that Lúnasa's intolerant of beef and when I got the test results back for her they did show she had a marked sensitivity to beef. I know she's also sensitive to duck but the test did not flag this as a problem.
Saoirse's results were: Egg (IGE 3) Duck, Lamb, Beef (IGE 1) Soya Bean (IGE 1) Cow's Milk (IGG 2). Saoirse was definitely intolerant of duck, beef and soy (worsened her pancreatitis symptoms and/or caused loose stools).
While they're not definitive, I'm glad I got the tests done - if only to find out about potential triggers.
