"WebPrecision levels vary depending on the analyte and the method. Generally, electrolytes and creatinine have very low CV% indicating very good precision. Enzymes and immunoassays typically have higher CV%. One other rule of thumb is that a method's CV or SD should be <1/8th of the reference range width. " - Ray's rule of precision
