amount of urine sample needed for urinalysis
No plastic tubes please. Collect at least 10 ml of urine. We try and standardize the volume of urine used for urinalysis. This is impossible to do if samples ranging from 0.5 ml (way too little to do anything useful with) to 100 ml are collected. In addition, we need a minimum of 10 ml of urine for electrophoresis. The urine protein concentration is very low and we need a minimum amount of protein to perform the electrophoresis.
