It's hard to tell because her color is probably dulled due to her poor health. If you own any other geckos, please keep this one far away, handle it last, wash your hands well after handling it and don't plan to use anything from her enclosure with anyone else again unless you wash it in a bleach solution. I know you know that she's thin, but she's really beyond thin and her survival is dubious. I just worry that she has crypto, which is why I've made the suggestions above.
