New skin patch can predict anaphylaxis before it occurs
A team at KAUST has developed AllergE, a tiny skin patch that can spot early signs of a severe allergic reaction—anaphylaxis—before you even feel it.
Using painless microneedles, the patch checks for IgE antibodies, which are elevated in response to common food allergens like eggs, nuts, milk, and seafood.
How does the AllergE patch work?
AllergE's microneedles are shorter than a millimeter and thinner than a hair. They gently reach just under your skin to sample fluid where allergy signals show up first.
Special sensors in the patch detect even tiny amounts of IgE and send real-time readings to help you stay ahead of any reaction.
Why is this a big deal?
Right now, testing for allergies usually means blood draws or pricking your skin—and waiting days for results.
The AllergE patch is way more sensitive and gives instant feedback while you go about your day.
The AllergE patch is unique in offering wearable, real-time tracking designed to help prevent anaphylaxis before it starts.
