Globulin is any of a number of simple proteins that occur widely in plant and animal tissues. Without adequate Globulin levels it can be difficult for the body to properly fight infection, clot or transport nutrients to the muscles, leading to health difficulties for the patient. Medical examinations must be done to determine if the globulin levels are where they should be, and what might be causing them to be lower or higher than normal. Medications can then be used to help return the globulin levels to the normal stage to avoid any potential dangers.
