24 hour urine collection process
- Urine is collected in a special container either white or brown in colour. The urine is collected in a special pan that either fits a toilet or the urinal. The collected urine is transferred from the pan to the small collection container and stored in a cool place.
- The 24 hour is accounted for from the time you collect the urine but as a general practice, it is usually recommended to collect it as soon as you wake up in the morning and clear the bladder.
- Flush the first time urination and do not store it. Note the time as the 24-hour time is calculated from here. All urine post the first flush is collected and refrigerate it either on ice or in a refrigerator. Try urinating at the same time post the 24-hour start time you initially noted to complete the process.
- You need to take it to the pathology lab near you as soon as possible after the process is over. If you are doing the process at home, your healthcare professional will give you specific instructions on how and where you should be taking it to.
- You might be asked to repeat the process depending on your health condition
