Calcium/Creatinine Ratio (Spot sample)

This test measures the ratio of calcium to creatinine in a spot urine sample, which is a single urine specimen collected at any time during the day.

The Calcium/Creatinine Ratio, Spot Urine test serves several clinical purposes, including:

• It helps determine how efficiently the kidneys are excreting calcium, which is crucial for maintaining overall calcium balance in the body.
• Abnormal calcium excretion can be indicative of kidney dysfunction, and this test aids in the assessment of renal health.
• It is used to diagnose conditions like hypercalciuria (excessive calcium in the urine), which can lead to kidney stones and other health issues.
• Patients with calcium-related disorders may undergo this test to monitor the effectiveness of treatment and adjust therapeutic interventions.

The Calcium/Creatinine Ratio, Spot Urine test may be recommended in the following scenarios:

• Individuals with a history of kidney stones or those at risk of developing them may undergo this test to assess their risk factors.
• It is valuable in the evaluation of kidney diseases or conditions affecting kidney function, where abnormal calcium excretion may be a concern.
• Patients with symptoms like frequent kidney stones, urinary tract issues, or unexplained bone pain may need the test to identify hypercalciuria as a potential cause.
• If you are receiving treatment for calcium-related disorders or kidney issues, your healthcare provider may use this test to monitor your progress.

Abnormal results in the Calcium/Creatinine Ratio, Spot Urine test may suggest various underlying conditions.

• Elevated Calcium/Creatinine Ratio: This may indicate hypercalciuria, which could be due to a variety of factors, including kidney diseases or metabolic disorders.
• Low Calcium/Creatinine Ratio: A decreased ratio may be related to hypocalciuria or other kidney issues.

You will provide a spot urine sample at any time during the day. No fasting or special preparation is typically required. Generally, there are no specific dietary or medication restrictions before this test. The urine sample will be collected in a sterile container and sent to the laboratory for analysis.

Additional tests that may be ordered in conjunction with the Calcium/Creatinine Ratio, Spot Urine test include:

• Blood Calcium Levels: To measure the concentration of calcium in the bloodstream, helping to assess overall calcium balance.
• Kidney Function Tests: Such as serum creatinine, glomerular filtration rate (GFR), and other markers of kidney function to comprehensively evaluate renal health.
