It's a fair question. Hank pushes back the sleeves of his shirt— thankfully, by now, he has found a change of clothes so he's no longer walking around in his pajamas— and crosses his arms.

"It's... hard to say. If I had any of my lab equipment I could at least test it for any chemical interference. But something tells me if it has been tampered with in some way, chemistry wouldn't be the way to tell."

Someone isn't all that fond of this magic-heavy place. Hank is much more a man of science.
