What is a ‘spot urine’ test?

A 'spot urine' test refers to a urine sample collected at a random time, rather than during a specific collection period or under controlled conditions. This method provides a snapshot of the urinary composition at that moment, making it convenient and straightforward for various analyses, including screening for certain conditions or substances.

Spot urine tests are often used for quick evaluations, such as checking for protein levels, glucose, or specific medications in the urine. The randomness of the collection allows for easy sampling in routine clinical practice, as it does not require the patient to adhere to strict timing or fasting protocols.

In contrast, urine samples taken during specific times, such as after fasting or collected over a 24-hour period, are designed for other types of analyses that require more controlled conditions or a comprehensive view of the urinary output over time.
