Thoroughly wash the area around the urethra. For males, the entire penis can be placed in the bag and the adhesive attached to the skin. For females, the bag is placed over the labia. Check your baby frequently and remove the bag after the infant has urinated into it. The urine is drained into a container for transport back to the health care provider.
Immunoelectrophoresis is a laboratory technique.
Electrical charges are used to separate and identify the various immunoglobulins. It uses a combination of protein electrophoresis and an antigen-antibody interaction. Protein electrophoresis indicates the presence of immunoglobulins as a group. Immunoelectrophoresis enhances the ability to identify the specific immunoglobulins through the use of antibodies that only react with the proteins of interest. The presence of a precipitin band indicates that the antigen is present for the monospecific antiserum used.
