What This Test Measures
Your urine sample is analyzed for a range of substances, including electrolytes like sodium, potassium, and calcium; organic acids such as lactate, pyruvate, and ketones; and other metabolites that may indicate metabolic disorders or kidney function. Some tests may also check for specific markers related to conditions like diabetes, kidney disease, or inherited metabolic disorders.
Why It’s Done
A 24-hour urine screen is often used when doctors suspect conditions like metabolic acidosis, kidney problems, or certain genetic disorders. It helps track how well your body processes certain substances over time.
Sample Collection
You’ll collect all urine for a full 24-hour period, starting from one point in the morning and ending the next morning. Your healthcare provider will guide you on proper timing and storage to ensure accurate results.
Common Conditions Monitored
This test may help diagnose or monitor conditions such as kidney disease, metabolic disorders (like those affecting amino acids or organic acids), or conditions affecting electrolyte balance.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: This test provides critical insights into how your body processes essential substances. Elevated or low levels of certain metabolites can signal metabolic disorders, kidney dysfunction, or other systemic health issues. Early detection may allow for timely medical intervention.
