Thats standard procedure with our lads to know there medical history! What is interesting is what you say that some so called allergies and not what they seem-i'm not a doctor so i don't know about humans! In animal terms personally i've never met an animal with a latex alleregy but it would be hard to spot if it did exist-i will continue to uise latex at work but we use nitrile for suspected animal poisons like rat poison as nitrile gloves will nbot disintegrate if you come in contact with it-quite unlike Latex!
