Did my husband mess up our son's skin prick allergy test? (arm, doctor)

[T2015]

My 2 year old had a skin prick test on his forrarms. He was seated on my husband's lap facing forward. Immediately after the allergen was placed on one of toddler's forearms, my husband turned that arm inward against my toddler's chest, with the allergen side now being against my toddler's shirt. My husband then held his other forearm out while the no-name badge, silent nurse continued to prick the other forearm. I was afraid the allergens had rubbed off so I unfolded my toddler's compromised arm and regretted I did not do it sooner. It was folded inwards for 30 seconds or less. That whole arm, which was folded inwards against my son's belly, was negative for allergies except for 1 spot, which was located on the farthest outer part of his forearm, and did not come in contact with my son's shirt.

Does anyone know if what my husband did (and nurse ignored) negated the results of the allergy test? It happened in clear view of the nurse but maybe she was lazy to reapply everything on that arm and start over. She did not give us any instructions at all. After the allergens were placed on the second forearm, I made sure my toddler did not touch his arms against anything. The whole thing was a horrible experience (not going there again) but that's another story. Has this happened to anyone? I know this test is not a 100 % accurate or a true diagnostic test and that there is a slight prick / scratch/ puncture to the skin when the allergen is placed. I'm just so upset over the whole experience, including with the doctor, and I can't find much online about it either. I would appreciate some feedback.
