Clinical Info
For specimen validity interpretations, the following rules are applied: Diluted: Creatinine is greater than or equal to 2mg/dL but less than 20mg/dL and Specific Gravity is less than 1.003. Substituted: Creatinine is less than 2mg/dL and the Specific Gravity is less than 1.003 or greater than or equal to 1.020. Adulterated: pH is less than 4 or greater than or equal to 11; Nitrite is greater than or equal to 500mg/L; Oxidant is greater than or equal to 200mg/L.
