What are the different types of liver function tests?

Your liver is an incredible organ that performs several functions to keep your body running smoothly. It performs over 500 different functions. One of its most important jobs is to break down food and convert it into energy. It also regulates the chemical levels in the blood and creates bile, a substance that carries away waste products from the liver.

The liver also:

  • Helps fight off infections
  • Cleans the blood of bacteria and particles
  • Neutralises toxins
  • Regulates several hormones
  • Produces enzymes and proteins needed for blood clotting
  • Metabolises drugs

Getting regular liver function tests can help keep you informed on how your liver is doing. Liver function tests are diagnostic tests that measure the levels of proteins and enzymes in your blood. By analysing these substances, any liver damage and disease can be detected and treated.

Types of Liver Function Tests

There are several types of liver function tests, including:

  • Alanine transaminase (ALT): ALT is an enzyme found in the liver that helps with the process of turning proteins into energy for your liver cells. When the liver is diseased or damaged, more ALT is released into the bloodstream and levels increase.
  • Aspartate transaminase (AST): AST is an enzyme that helps metabolise amino acids. Like ALT, AST is usually found in lower levels within the blood. Increased AST levels may be a sign of liver damage, disease or muscle damage.

  • Albumin and total protein: Albumin is one of several proteins made by your liver. Your body needs Albumin to fight infections and to perform other important functions. If your levels of albumin are too low, you may have liver disease or liver damage.

  • Bilirubin: Bilirubin is a substance that passes through the liver before being released from the body through your stool. Elevated levels of bilirubin might indicate liver damage or disease or anaemia.

  • Prothrombin time (PT): PT is the amount of time it takes for your blood to clot. If you have elevated PT levels, you might have liver damage. Some blood-thinning drugs can also elevate PT levels.

Are you searching for a lasting solution to your facial wrinkles? then you're on the right article. Research has it that there are processes that facilitate wrinkle formation, thereby contributing to making us have a much older appearance and they include:  our everyday facial expression and loss of skin elasticity. Loss of skin elasticity happens alongside the loss of volume and it gives the long-term effect of sagging; it gives the feel of loose muscles, making them lack the firmness they normally should have.  Also, our everyday facial expressions refer to how we use our facial muscles. There are typical facial wrinkles with negative connotations and they are frown lines or furrows between the eyes which makes us look like we are intensely worried or negative. Dealing with wrinkles should not be so much of a problem because there are now medically acceptable ways to deal with it, they are called anti-wrinkle treatment.

What are the symptoms of Japanese Encephalitis?

Japanese Encephalitis is inflammation in the brain caused by a virus called Japanese encephalitis virus (JEV). South Asia is the common grounds to get this disease. The virus is spread from the bite of the infected mosquito. The virus enters the mosquitoes from pigs and birds. Fortunately is not contagious from human to human. Agricultural fields and rural areas are common places where this disease is seen. 90% of the patients are asymptomatic in the first phase. Flu and diarrhoea are seen in the first two days. Headaches, vomiting, raised tones, intracranial pressures increase and seizures are seen in phase 2.  Clinical findings are used to diagnose Japanese Encephalitis.  Lymphocytosis is seen in the blood.
