Where Is The Best Examination For Liver Disease? Liver Examination Procedure
Liver function test is a process through liver biochemical tests, ultrasound ... to evaluate the activity, status and function of liver cells. This examination process helps physicians identify and accurately diagnose liver diseases, thereby offering effective treatment regimens for patients.
Why must a liver examination?
A liver function test is essentially a biochemical test to diagnose pathologies or liver damage. This test measures the concentration of protein and enzymes in the blood. This enzyme is a special kind of protein, acting as a catalyst, promoting the body's reactions
In addition, the liver function test also helps you know if the liver is working well or not, screening for the risk of liver disease.
The physiological function of the liver is very complex, so tests to check liver function are also quite many, mainly testing the concentration of ALT, AST, Valley Acyl genetic Titan Enzyme or the concentration of direct birilubin, cockroach next. What tests the patient will be assigned to perform functional tests depends on the doctor's order. Based on the results of the test, the doctor will identify the status of liver damage, detect the risk and screen for other possible liver diseases and develop an effective treatment regimen for the patient.
Therefore, when patients see signs and symptoms of suspected liver disease, they should visit health facilities for timely testing, diagnosis and treatment.
When you see the signs, symptoms suspected liver disease should see a liver
What does a liver exam include?
The first thing is that patients need to seek medical facilities specialized liver and liver to get the best examination. Here, to serve the process of examination and accurate diagnosis of the disease, the patient will be appointed by the doctor to perform liver function tests, ultrasound to look at the liver image
- General abdominal ultrasound, liver ultrasound is a diagnostic imaging method used to view liver images and liver damage. The advantage of this method is fast and less expensive. Ultrasound is usually done at fasting, used to detect tumors in the liver that can be benign (noncancerous) or malignant (cancerous) but cannot distinguish these two types. During an ultrasound, the doctor will measure the tumor size. Even so, even if the ultrasound results are normal, this does not mean that the liver has no problems.
In addition to performing an ultrasound, your doctor will order tests of liver function, based on these indicators will help your doctor diagnose the disease most accurately. Tests include:
Measurement of activity of AST (GOT), ALT (GPT), GGT (Gama Glutamyl Transferase), ALP (alkaline phosphatase), LDH (Lactate Dehydrogenase)
+ AST is the enzyme found in muscles, heart, liver.
When the liver is damaged, AST is released into the bloodstream, leading to increased AST levels. Although the AST does not reflect specific liver damage, if the AST increases, you may think of liver or muscle diseases.
The normal value for AST is <37 UI / L in adults and may be higher in children or infants. AST is usually ordered in combination with ALT to form a common liver enzyme test kit. + ALT (GPT) is an enzyme found mainly in liver cells, in addition to the heart, skeletal muscle, kidney. Like AST, when the liver is damaged or has a loss of metabolic function, ALT will be released into the bloodstream causing an increase in ALT. The normal limit for this indicator is <40 UI / L. Because it is mainly in the liver, if the ALT is elevated, it will reflect liver diseases.
This index is more sensitive and specific to liver diseases than AST.
Testing of liver indices
+ GGT (Gama Glutamyl Transferase) is an enzyme not only found in liver but also in kidney, pancreas, spleen and small intestine. This is a very sensitive test to evaluate the excretion function of the liver but is not specific due to the influence of many other factors. Normal GGT is 20-40 UI / L, the male is higher than the female. This index reflects the damage of the liver related to the cause of alcohol, viral hepatitis, metastatic cancer, use of drugs that cause enzyme induction in the liver, non-alcoholic fatty liver ... or obstruction of the bile duct.
+ ALP (alkaline phosphatase) is an enzyme found in bones, bile ducts and liver. This test is often ordered along with many other tests to assess liver damage. The normal value for ALP is 120 UI / L. If the ALP value is high, you may think of hepatitis, biliary obstruction or bone-joint disease. Therefore, ALP can increase in young children and adolescents who are developing bone or women who are pregnant.
+ LDH (Lactate Dehydrogenase) This enzyme is found in all tissues in the body (heart, muscle, bone, kidney, red blood cells, platelets, lymph nodes) which is a non-specific test for the liver. An elevated LDH index is commonly found in hepatocellular necrosis, liver shock.
Especially if long-term LDH accompanied by increased ALP is often thought of malignant infiltrative lesions in the liver.
