Step 2 compare alt and alp levels key facts about alt and alp alt is found in high concentrations within hepatocytes and enters the blood following hepatocellular injury.

Liver function test values diagnostic interpretation.

The tests measure the levels of certain enzymes and proteins in your blood. Signs of liver dysfunction examination palmar erythema spider naevi small liver bigg p spleen ascites hepatic encephalopathy imaging nodular liver edge portal real liver function tests synthetic function prothrombin time. Some of these tests measure how well the liver is performing its normal functions of producing protein and clearing bilirubin a blood waste product. Liver enzymes especially alp are not specific for primary liver disease.

Beyond the liver function tests prothrombin time provides another marker of liver synthetic function and a low platelet count suggests portal hypertension. Hence the commonly used term liver function test is inaccurate and the term liver tests is used in this chapter. The severity of liver dysfunction or biliary obstruction is reflected in the bilirubin level and the degree of liver synthetic function can also be indicated by the albumin level. Guidelines on the interpretation and evaluation of abnormal liver test results have been published.

The liver performs different kinds of biochemical synthetic and excretory functions so no single biochemical test can detect the global functions of the liver. Bilirubin in body is a careful balance between. 1 2 useful algorithms are presented that parallel the recommendations in this chapter. Diagnostic value of bilirubin levels.

Total protein should be between 63 80g l 6 3 to 8 0 g dl albumin. To evaluate their clinical significance a combination of history clinical signs physical examination diagnostic imaging and other liver function test results. It is a series of blood tests used to diagnose and monitor the condition of the liver. Liver function test normal values total protein.

It measures the levels of some enzymes and proteins present in the blood. Normal values for albumin are between 35 50 g l 3 5 to 5 0 grams per deciliter g dl bilirubin. Liver function tests are a battery of tests for the initial detection and management of liver diseases. Liver function tests are blood tests used to help diagnose and monitor liver disease or damage.
