There are two ways for a 24-hour urine specimen to be collected.
- Ambulatory patients can use a plastic container called a "hat" in the toilet to collect urine when the person uses the bathroom. *Only urine is needed. The urine is poured into a special collection jug. In 24 hours, the jug is delivered to the doctor's office or lab, as directed.
- Non-ambulatory patients are typically catheterized. Urine is held in the catheter bag until regularly emptied, when it is added to the jug instead of being dumped. In 24 hours, the jug is transported to the hospital lab.
* In both, collection continues for a full 24 hour period. The patient does not change their diet, fluid intake, or activity level, just collects what they would normally urinate into the toilet.

How do you collect a 24 hour urine specimen?
To collect a 24-hour urine specimen, start by discarding the first morning urine and then collect all urine over the next 24 hours in a clean container kept on ice or in a refrigerator. Make sure to record the start and end times of the collection period and store the specimen properly to maintain its integrity for testing.
What are the types of urine specimen?
The types of urine specimens commonly used for testing include random urine, first-morning urine, clean-catch midstream urine, and 24-hour urine collection. Each type provides different information based on the timing and collection method.
When a quantitative tests are needed for different substances what urine specimen is usually requested?
random,fasting timed, 24 hour, catheterized
How is the calculation of 24 hour urine creatinine done?
To calculate the 24-hour urine creatinine, the amount of creatinine excreted in the urine over a 24-hour period is determined by collecting all urine passed during this time. The creatinine concentration in this pooled urine sample is then measured. Finally, the creatinine concentration is multiplied by the volume of the urine collected to obtain the total amount of creatinine excreted in a 24-hour period.
What happen when a urine specimen is allowed to sit for an hour?
When a urine specimen is allowed to sit for an hour, bacterial growth may increase due to the warm and moist environment, potentially leading to inaccurate test results. Additionally, the pH and chemical composition of the urine may change, which can affect the accuracy of certain tests such as urine culture or urinalysis. It is always best to process urine specimens promptly to ensure accurate results.
What are Nine types of urine specimens that can be collected?

How do you collect specimen for benze-jones protein test?
To collect a specimen for a Bence Jones protein test, a 24-hour urine collection is usually required. You will be provided with a container to collect all urine passed during a 24-hour period, starting with an empty bladder and ending with a final collection at the same time the following day. The urine specimen is then sent to a lab for analysis to measure the presence of Bence Jones proteins.
Why must the examination of urine be done on a 24 hour specimen?
The examination of urine using a 24-hour specimen is essential to accurately assess kidney function, metabolic disorders, and the excretion of substances that may vary significantly throughout the day. This approach captures all urine output within a 24-hour period, providing a comprehensive picture of renal function and allowing for more reliable measurement of substances like electrolytes, proteins, and hormones. It minimizes the variability and fluctuations that can occur with random urine samples, ensuring more precise diagnostic results.

A Urine sample collected after a meal is called?
2-hour postprandial specimen
What is the best specimen for a Bence Jones protein test?
The best specimen for a Bence Jones protein test is a 24-hour urine sample. This allows for the most accurate measurement of protein excretion over a full day, which is important for detecting and monitoring conditions such as multiple myeloma.
When a quantitative tests are needed for different substances what urine specimen is usually requested?
random,fasting timed, 24 hour, catheterized
How is the calculation of potassium from a 24 hour urine collection done?
To calculate the amount of potassium excreted in a 24-hour urine collection, you multiply the potassium concentration in the urine sample by the total volume of urine collected over the 24-hour period. This will give you the total amount of potassium excreted in that time frame.
