We used the Lil Cactus kit for my 4-year-old instead of scheduling a specialist visit, and the finger-prick was over in seconds. The report came back clear and easy to read, and it confirmed what we suspected about her egg sensitivity.

The kit itself was well designed and my son barely noticed the prick, but it took almost two weeks to get results back. Worth it for the convenience, just plan ahead if you need answers quickly.

★★★☆☆
It's a solid first screening tool and cheaper than an in-office panel, but the number of allergens tested was more limited than I expected. We ended up following up with our pediatrician anyway for a fuller picture.
