The liver span is a measurement performed during physical examination ... Normal liver span is 6–12 cm (2.4–4.7 in), but varies with age, height, and weight ...
Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span. [citation needed] On abdominal ultrasonography, the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in ...
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.
About 20,000 protein coding genes are expressed in human cells and 60% of these genes are expressed in a normal, adult liver. [ 34 ] [ 35 ] Over 400 genes are more specifically expressed in the liver, with some 150 genes highly specific for liver tissue.
Despite being commonly taught to medical trainees, the liver scratch test's value as part of the abdominal physical exam has been controversial as it has historically performed poorly. While it has been proposed to abandon the test altogether, [ 5 ] [ 6 ] some studies have suggested that the scratch test is at least as accurate as percussion ...
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 volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] ... The average life span of the ... a normal feature of 30-40% of hepatocytes in the adult human liver ...
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [ 1 ] [ 2 ] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [ 3 ]
