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.
The typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types. [3]
The magnitude of leukocytopenia (white blood cell depletion) reflects severity of liver injury. Histologic features include Mallory bodies, giant mitochondria, hepatocyte necrosis, and neutrophil infiltration in the area around the veins. Mallory bodies, which are also present in other liver diseases, are condensations of cytokeratin components ...
Damaged hepatocytes release Danger associated molecular patterns (DAMPs) which are molecules that lead to further activation of the immune system's inflammatory response and further hepatocyte damage. [7] The chronic inflammation seen in alcoholic hepatitis leads to a distinctive fibrotic response, with fibrogenic cell type activation.
Simple blood tests may help to determine the magnitude of the disease by assessing the degree of liver fibrosis. [28] For example, AST-to-platelets ratio index (APRI score) and several other scores, calculated from the results of blood tests, can detect the degree of liver fibrosis and predict the future formation of liver cancer.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
The condition is strongly associated with or caused by type 2 diabetes, insulin resistance, and metabolic syndrome (defined as at least three of the five following medical conditions: abdominal obesity, high blood pressure, high blood sugar, high serum triglycerides, and low serum high-density lipoprotein).
If HBsAg is present, a second test – usually done on the same blood sample – that detects the antibody for the hepatitis B core antigen (anti-HBcAg) can differentiate between acute and chronic infection. [85] [89] People who are high-risk whose blood tests negative for HBsAg can receive the hepatitis B vaccine to prevent future infection.
