Aminoaciduria

Amino acids - urine; Urine amino acids

Aminoaciduria is an abnormally high amount of amino acids in the urine. Amino acids are the building blocks for proteins in the body.

Urine sample

A clean-catch urine sample is performed by collecting the sample of urine in midstream. Men or boys should wipe clean the head of the penis. Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well. A small amount of urine should initially fall into the toilet bowl before it is collected (this clears the urethra of contaminants). Then, in a clean container, catch about 1 to 2 ounces of urine and remove the container from the urine stream. The container is then given to the health care provider.
