A number of pitfalls can be encountered in the interpretation of common blood liver function tests. When liver cells are damaged, AST leaks out into the bloodstream and the level of AST in the blood becomes elevated. However, the fact that ferritin is an acute phase protein, affected not only by the iron status of the body, but also by acute or chronic inflammation, malignancies and liver disease, makes the interpretation of that test challenging. The superiority of ferritin over other measurements in the diagnosis of ID has been proven by several studies. Interpretation of the House-Tree-Person (HTP) Psychology Test.

Results of HBV serologic markers can be reported qualitatively or quantitatively as international units (IU) or signal per cutoff (s/c) value. AST, or aspartate aminotransferase, is one of the two liver enzymes. Explanation of test results: A normal INR is 1.0. People who drink alcoholic beverages a lot. 8. name and discuss at least 2 serological lab tests and Guidelines on the interpretation and evaluation of abnormal liver test results have been published. These tests can be used to assess liver functions or liver injury. Multiple serum chemistries can be used to assess hepatic function and/or injury. A calculated ratio of albumin to globulin (A/G ratio) may also be reported. These tests can be normal in patients with … We call this hypothyroidism. Liver Function Test 1. Hepatitis B virus (HBV) testing plays an important role in detection, classification, and management of HBV disease. In addition, interpretation of liver biopsy results may vary.

Elevated levels of AST and ALT may signify the level of liver damage in a person. The CPK-MB test is a cardiac marker used to assist diagnoses of an acute myocardial infarction.It measures the blood level of CK-MB (creatine kinase myocardial band), the bound combination of two variants (isoenzymes CKM and CKB) of the enzyme phosphocreatine kinase.. An albumin blood test is a type of liver function test. The levels of particular enzymes or proteins in the blood are measured using this test.

Functions: Liver is the largest Organ of the body weighing about 1.5kg. The main tests in the liver function tests are prothrombin time, APTT, albumin, bilirubin.. A liver function test is recommended for the following reasons: The test is quick and easy. 2. Patterns of abnormalities suggest the category of disease. Often clinicians are faced with reports that do not tally with the clinical condition of the patient and they face difficulty in interpreting the LFT. Liver Tests. LIVER FUNCTION TESTS (LFT) M.PRASAD NAIDU Msc Medical Biochemistry, Ph.D Research scholar. The House-Tree-Person (HTP) test in clinical psychology is part of the series of a group of projective tests which help in the assessment of personality traits. An albumin test may also be part of a comprehensive metabolic panel, a test that measures several substances in your blood. 2. A kidney function panel is a group of tests that may be performed together to evaluate kidney (renal) function. Personal Health Status (NOC 2006) 1. If your T4 levels are too high, and TSH is low, everything runs at a faster rate and you may experience heat intolerance or weight loss. Alanine amino transferase (ALT, SGPT) - enzyme found mostly in the cells of the liver and kidney; a useful test for detecting liver damage 6. name and discuss at least 5 components of the liver function lab test and the nursing implications. 3, mARch 2011 A. ... Liver function tests. cerebrospinal fluid analysis lab test and the nursing implications. AST is a protein made by liver cells. It determines the health of the liver by evaluating the level of liver enzymes, proteins or bilirubin in the blood. History. Clinical Examination A comprehensive collection of clinical examination OSCE guides that include step-by-step images of key steps, video demonstrations and PDF mark schemes. Extremely overweight or obese individuals. Alkaline phosphatase (ALP) - enzyme found in bone, the liver, and other tissues; elevated levels of ALP in the blood are most commonly caused by liver disease or bone disorders. Tests done in clinical laboratories do not measure any functional capacity of the liver. ALP and GGT elevations can indicate a problem with bile flow through the liver. Thus, development of a rational and cost-effective approach to these patients is important. Test interpretation. Interpretation of abnormalities in liver function tests is a common problem faced by clinicians. Hence, the commonly used term liver function test is inaccurate, and the term liver tests is used in this chapter. It is a group of tests that gives a statement on the health of a patient’s liver. LIVER FUNCTION TESTS (LFT) M.PRASAD NAIDU Msc Medical Biochemistry, Ph.D Research scholar. Initial screening tests for liver disease include a CBC, biochemistry panel, and urinalysis. Liver diseases are generally classified as hepatocellu-lar, cholestatic, and infiltrative. Liver function tests are blood tests that measure different enzymes and proteins in the liver, including albumin. Interpretation of your test results can involve consideration of multiple factors: The degree of elevation: Very high levels are often seen with blockages of the bile ducts, but high levels alone cannot distinguish between liver problems and other conditions. Thankfully it is often possible to return abnormal liver function tests to normal with our dietary program. Liver is called kitchen of our body. INR is related to the prothrombin time (PT). Gall bladder contraction with feeding releases bile acids into the intestine. Liver biopsy results are limited by sampling error, as abnormal findings may be missed if only normal tissue is retrieved. Each increase of 0.1 means the blood is slightly thinner (it takes longer to clot). The HTP test is also administered to identify mental disorders like schizophrenia. Liver function tests (LFTs) are a panel of blood markers (Table 1) used to assess and monitor several diseases. A liver function test is also ordered in people with: A family history of liver disease Severely alcoholic Exposed to hepatitis virus Taking drugs that may cause liver-related damage; Who should submit for a liver function test? 1,2 Useful algorithms are presented that parallel the recommendations in this chapter. If there is serious liver disease and cirrhosis, the liver may not produce the proper amount of proteins and then the blood is not able to clot as it should. An initial step in detecting liver damage is a simple blood test to determine the level of certain liver enzymes (proteins) in the blood. Interpreting the liver function/disease test results requires taking into account the whole clinical picture, as a healthy person who trains hard can have elevations in some labs to the same degree that is seen in patients with liver disease.
