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 third gene array shows a deuteranopia genotype; the fourth shows a normal color vision genotype. When unequal recombination happens with breaks between the genes (depicted by blue lines), a gene can be essentially deleted from one of the chromosomes. This gene deletion leads to protanopia or deuteranopia (congenital red–green dichromacy).
Treatments for heart failure include medications, an intra-aortic balloon pump, a ventricular assist device, heart valve replacements, extracorporeal membrane oxygenation (if the heart failure worsens suddenly and especially if an infection was the cause), an artificial heart, or a heart transplant (from a deceased human donor, or from a pig ...
Liver diseases, including conditions such as non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ALD), and viral hepatitis, are significant public health concerns worldwide. In the United States, NAFLD is the most common chronic liver condition, affecting approximately 24% of the population, with the prevalence rising due ...
Liver diseases may be diagnosed by liver function tests–blood tests that can identify various markers. For example, acute-phase reactants are produced by the liver in response to injury or inflammation. The most common chronic liver disease is nonalcoholic fatty liver disease, which affects an estimated one-third of the world population. [59]
The Ishihara color test is the test most often used to detect red–green deficiencies and most often recognized by the public. [1] Some tests are clinical in nature, designed to be fast, simple, and effective at identifying broad categories of color blindness. Others focus on precision and are generally available only in academic settings. [56]
Liver biopsy is often required for the diagnosis of a liver problem (jaundice, abnormal blood tests) where blood tests, such as hepatitis A serology, have not been able to identify a cause. It is also required if hepatitis is possibly the result of medication , but the exact nature of the reaction is unclear.
The diagnosis can be suspected by imaging, with typical characteristics centering around appearance of the liver, typically with CT, ultrasound or MRI.Traits that raise suspicion for the infection include intra- and extra- hepatic dilatation and strictures with intraductal pigmented stones, usually in the absence of gallstones and with regions of segmental liver atrophy, particularly the ...
