Calcium Creatinine Ratio Calculator

The calcium-to-creatinine ratio is calculated by dividing the concentration of calcium in urine by the concentration of creatinine in urine. It’s used to assess how efficiently the kidneys handle calcium. A ratio of 55 indicates a higher-than-normal excretion of calcium relative to creatinine, suggesting potential issues with calcium metabolism or kidney function. Further evaluation is needed to determine the cause and appropriate management.

FAQs

• How do you calculate calcium creatinine ratio? The calcium-to-creatinine ratio (Ca/Cr ratio) is calculated by dividing the concentration of calcium in urine by the concentration of creatinine in urine. The formula is: Ca/Cr ratio = Urine calcium concentration (mg/dL) / Urine creatinine concentration (mg/dL).
• What is a normal CA CR clearance ratio? A normal calcium creatinine clearance ratio is typically less than 0.2, indicating that the majority of filtered calcium is reabsorbed by the kidneys.
• What does urine calcium to creatinine ratio mean? The urine calcium-to-creatinine ratio is a measure of the amount of calcium excreted in the urine relative to the amount of creatinine excreted. It helps assess how efficiently the kidneys are handling calcium.
• What is considered a high level of calcium in urine? A high level of calcium in urine is typically considered to be a urine calcium concentration greater than 300 mg/day or a calcium-to-creatinine ratio greater than 0.2.
• How do you calculate creatinine to BUN ratio? The creatinine-to-BUN ratio is calculated by dividing the concentration of creatinine in blood (usually in mg/dL) by the concentration of blood urea nitrogen (BUN) in blood (also in mg/dL). The formula is: Creatinine/BUN ratio = Blood creatinine concentration (mg/dL) / Blood BUN concentration (mg/dL).
