A question about creatinine

  1. Does anyone know of a source or formula that is used to correlate a patient's serum creatinine level with % glomerular or kidney function?
    Thanks for the assist!

    Table: Serum Creatinine and Kidney Function

    Serum Creatinine (mg/dL)*
    Approximate Nephron Loss

    Less than 50% of nephrons lost
    Normal Function

    Between 50% and 75% of nephrons lost

    Between 75% and 90% of nephrons lost
    Bigger Problem

    More than 90% of nephrons lost
    End Stage Renal Disease

    *: milligrams of creatinine per deciliter of serum

    Hope this is what you were looking for!
