Kidney stone risk profile
What is being analysed?
A kidney stone risk profile is a comprehensive examination aimed at identifying factors that increase the likelihood of developing kidney stones. This profile assesses various parameters such as urine composition, blood chemistry, and other relevant markers to determine an individual's susceptibility to kidney stone formation.
What does the result mean?
The results of a kidney stone risk profile provide valuable insights into an individual's risk of developing kidney stones. It helps in understanding the underlying causes and contributors to stone formation, allowing for targeted preventive measures and treatment strategies.
Why perform the analysis?
Performing a kidney stone risk profile is crucial for individuals who have a history of kidney stones or exhibit symptoms suggestive of stone formation. It aids in early detection, risk stratification, and formulation of personalized interventions to prevent the recurrence of kidney stones.
What sample is required?
A urine sample is typically required for the kidney stone risk profile. This sample is collected either as a random specimen or as a 24-hour urine collection, depending on the specific parameters being analysed.
Is any prior preparation necessary?
Prior preparation may be necessary depending on the specific instructions provided by the healthcare provider or laboratory conducting the analysis. This may include dietary restrictions, temporary cessation of medications, or specific instructions for urine collection.
How is it used?
The kidney stone risk profile is used to assess various parameters including urinary pH, calcium, oxalate, citrate, uric acid, and other constituents. These values are interpreted collectively to determine the risk of kidney stone formation and guide interventions such as dietary modifications, hydration strategies, and medication therapy.
What are the normal values?
Parameter |
Normal range |
---|---|
Urinary pH |
5.0 - 7.0 |
Calcium |
< 250 mg/day |
Oxalate |
< 40 mg/day |
Citrate |
320 - 640 mg/day |
Uric acid |
< 750 mg/day |
What does having altered values mean?
Altered values in the kidney stone risk profile may indicate an increased risk of kidney stone formation. For example, high levels of calcium or oxalate in the urine, along with low urinary citrate levels, may predispose individuals to stone formation. Interpretation of these values should be done in conjunction with clinical assessment to develop an appropriate management plan.
In summary, the kidney stone risk profile is a valuable tool for evaluating an individual's susceptibility to kidney stones and guiding preventive measures. Understanding the significance of the results and timely intervention can help reduce the burden of kidney stone disease and improve overall renal health.
