**Semantic type:** Quantitative Concept

**Definition:** A formula that estimates liver pathology through the assessment of a six-parameter blood test, taking into account subject age. Fibrometer regression function = -0.007 platelets (Giga/L) - 0.049 prothrombin index (%) + 0.012 aspartate aminotransferase (UI/L) + 0.005 alpha2-macroglobulin (mg/dL) + 0.021 hyaluronate (g/L) - 0.270 urea (mmol/L) + 0.027 age (years) + 3.718.
