  2. Elevated transaminases - Wikipedia

    en.wikipedia.org/wiki/Elevated_transaminases

    However, very high elevations of the transaminases suggests severe liver damage, such as viral hepatitis, liver injury from lack of blood flow, or injury from drugs or toxins. Most disease processes cause ALT to rise higher than AST; AST levels double or triple that of ALT are consistent with alcoholic liver disease. [citation needed]

  3. AST/ALT ratio - Wikipedia

    en.wikipedia.org/wiki/AST/ALT_ratio

    The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.

  4. Liver function tests - Wikipedia

    en.wikipedia.org/wiki/Liver_function_tests

    Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.

  5. Alanine transaminase - Wikipedia

    en.wikipedia.org/wiki/Alanine_transaminase

    Alanine transaminase (ALT), also known as alanine aminotransferase (ALT or ALAT), formerly serum glutamate-pyruvate transaminase (GPT) or serum glutamic-pyruvic transaminase (SGPT), is a transaminase enzyme (EC 2.6.1.2) that was first characterized in the mid-1950s by Arthur Karmen and colleagues. [1]

  6. Portal hypertension - Wikipedia

    en.wikipedia.org/wiki/Portal_hypertension

    Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg. [5]

  7. Iron overload - Wikipedia

    en.wikipedia.org/wiki/Iron_overload

    Other risk factors for liver damage in hemochromatosis include alcohol use, diabetes, liver iron levels greater than 2,000 μmol/gram and increased aspartate transaminase levels. [7] The risk of death and liver fibrosis are elevated in males with HFE type hemochromatosis but not in females; this is thought to be due to a protective effect of ...

  8. FibroTest - Wikipedia

    en.wikipedia.org/wiki/FibroTest

    FibroTest has the same prognostic value as a liver biopsy. FibroSure uses quantitative results of five serum biochemical markers, α2-macroglobulin, haptoglobin, apolipoprotein A1, bilirubin, gamma glutamyl transpeptidase (GGT), with a patient’s age and gender to generate a measure of fibrosis and necroinflammatory activity in the liver.

  9. Glutamate dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Glutamate_dehydrogenase

    Elevated blood serum GLDH levels indicate liver damage and GLDH plays an important role in the differential diagnosis of liver disease, especially in combination with aminotransferases. GLDH is localised in mitochondria, therefore practically none is liberated in generalised inflammatory diseases of the liver such as viral hepatitides. Liver ...
