Sample Collection and Handling

 "How much blood can I get from that little critter?" 

A good rule of thumb for small animals is that total blood volume is ~ 10% of body weight in grams. It is generally considered safe to remove 10% of the total blood volume in healthy animals.

Never quite grasped the decimal system? No good at math? Spending too many hours "studying" at Cavanaugh's?

Enter the animal's weight in grams:
