Creatinine - Spot Urine Test

It is a test that measures the amount of creatinine in a single urine sample to help evaluate kidney function.

The test is performed to assess how well the kidneys are filtering wastes from the blood, to monitor kidney function in patients with known kidney conditions, or as a part of routine health screening.

A single urine sample is collected at any time of the day in a sterile container provided by the laboratory. It is important to follow the collection instructions closely.

The normal range for creatinine in a spot urine sample can vary depending on age, gender, and muscle mass. Higher levels of creatinine may indicate decreased kidney function, while lower levels can be normal, especially in individuals with lower muscle mass.

Factors that can affect the results include muscle mass, age, gender, diet, medications, hydration status, and kidney function.

No specific preparation is needed. Just follow the instructions provided by the laboratory for urine collection.
