Urine, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
This test necessitates a 24-hour urine collection. You will need a clean, large container for collecting urine during the entire 24-hour period. Your healthcare provider will provide you with specific instructions and a container for this purpose.
Test Time:
The test takes 24 hours to complete since it collects every urine produced during that time period. After collection, the urine sample is sent to a laboratory for analysis, and results are typically available within a few days.
Test Normal Range:
The normal range for 24-hour urinary creatinine excretion can vary based on factors such as age, sex, and muscle mass. Reference values are typically provided by the laboratory.
What is the Test?
The 24-hour urine creatinine test measures the amount of creatinine excreted in your urine over a 24-hour period. Creatinine is a waste product of muscular metabolism.This test helps assess kidney function and muscle mass.
Test Procedure:
To complete the 24-hour urine creatinine test: Discard the first morning urine and note the time. Collect all urine produced over the next 24 hours in the provided container, starting and ending at the same time each day.During collection, keep the container in a cool place.Return the container to the lab or healthcare provider as instructed.
When to Take the Test:
This test is often used to assess kidney function, particularly in individuals with kidney disease or those taking medications that can affect the kidneys. It may also be used to estimate muscle mass in some cases.
Who Should Take This Test:
Individuals with known or suspected kidney disease. Those taking medications that can affect kidney function. People with conditions that may impact muscle mass. Athletes and bodybuilders who want to monitor their muscle mass.
Precautions for Exceptional Cases (Pregnancy, etc.):
