This calculator helps determine THC creatinine ratio to estimate THC concentration in urine, commonly used in drug testing scenarios.
Learn how to use the THC Creatinine Ratio Calculator and its working principles for drug testing interpretation.
The THC Creatinine Ratio is calculated by dividing the concentration of THC in urine (ng/mL) by the concentration of creatinine (mg/dL). This ratio helps normalize THC concentrations across different urine samples, accounting for individual differences in muscle mass and creatinine production.
While laboratory cutoffs for THC vary, general guidelines suggest:
This calculator provides general guidance only. Individual factors such as hydration status, kidney function, and metabolism can affect results. Always consult with a healthcare professional or toxicologist for definitive interpretation of drug test results.
