What occurs if a urine specimen is allowed to stand for more than 1 hour at room temperature?
If a urine specimen is left standing for more than 1 hour at room temperature, it may undergo bacterial proliferation, leading to potential contamination. Additionally, there can be changes in the chemical composition of the urine, such as breakdown of certain components like glucose and ketones. This can result in inaccurate test results and difficulty in interpreting the findings.
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.
How soon must a urine specimen reach the laboratory?
How soon a specimen of something must reach the laboratory depends partly on the reason for which it is being sent to the laboratory, environmental conditions during storage and transit, and the stability of the substances the specimen consists of. A urine specimen must be refrigerated during storage and transit and arrive in the lab within an hour or two. It cannot sit out because warmth will allow bacteria, if present, to begin to grow in numbers.
What is a 24 hour urine specimen?
A 24-hour urine specimen is a collection of all urine produced over a 24-hour period. It is often used to measure various substances in the urine that can provide important diagnostic information about kidney function, hormone levels, or certain metabolic disorders. The collection must be properly stored and returned to the lab for analysis.
What are Nine types of urine specimens that can be collected?
Random urine sample First morning urine sample Midstream clean-catch urine sample 24-hour urine collection Timed urine sample Postprandial urine sample Suprapubic aspiration specimen Catheterized urine specimen Pediatric urine bag specimen

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.

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.
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.
