What will my Red Cross Disaster Volunteer health screening involve?

[expatriot]

I am an able-bodied 28 year old (although on the scrawny, pencil-necked, pencil armed) male who will have no problem lifting the 50 1b. load criteria in the paper repeated throughout the day but I have Crohn's Disease that is almost entirely in remission. I am going to get a Remicaid infusion on the 9th, the day before my training starts and it lasts for 2 months and my "tour" is going to be 3 weeks. I don't have any problems like I used to before I got on the Remicaid infusions but I do get mild to moderate cramping every ONCE in a while that can be fairly easily relieved but this usually only happens in the evenings and even so I can work through it no problem. I am just worried that if they get my medical records they'll think I am an unacceptable risk, especially since dysentery, cholera and typhoid attacks the gastro-intestinal tract.

I don't want a medical deferment on this one! I want to serve!
