 if you accidentally lose urine on the outside walls of the container wash and dry
 container labeled with patient name, date and time of harvest and will be sent immediately to the laboratory accompanied by the form of the analysis
 delay in sending the sample to the laboratory can alter the final results of the sample
 wash flasks / urinary graduated beaker is removed from the patient’s bedside
