Schematic reliability of diagnostic means. In clinical practice, a blood test is more reliable than liver pathology since the blood test is based on an algorithm that was calculated with expert pathologist as reference (black arrow with red background). There is little procedure variability for blood tests due to excellent interlaboratory reproducibility, contrary to the large inter-observer disagreement for liver pathology and, to a lesser degree, for elastometry. The size of observers is proportional to published observer variability.
