Differential Diagnosis
When a pathological process interferes with the normal functioning of the metabolism and excretion of bilirubin just described, jaundice may be the result. Jaundice is classified into three categories, depending on which part of the physiological mechanism the pathology affects. The three categories are:
| Category | Definition |
|---|---|
| Pre-hepatic/ hemolytic | The pathology is occurring prior to the liver. |
| Hepatic/ hepatocellular | The pathology is located within the liver. |
| Post-Hepatic/ cholestatic | The pathology is located after the conjugation of bilirubin in the liver. |

Famous quotes containing the word differential:
“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)
