Liver Test Interpretation - Approach to the Patient with Liver Disease: A Guide to Commonly Used Liver Tests The pattern of liver test abnormality is hepatocellular. The AST is typically in the 100 to 200 IU/L range, even in severe disease, and the ALT level may be normal, even in severe cases. The AST level is higher than the ALT level, and the ratio is greater than 2:1 in 70% of patients.

Using Liver Enzymes AST and ALT to Diagnose Liver Damage and Disease What Are Normal AST and ALT Levels? The normal levels of AST and ALT vary from person to person and depend on your ​body mass index (BMI), or the ratio of your height and weight. A small amount of AST and ALT is normally in your blood, so it's really a large increase over your normal level that indicates a problem.

Blood tests for liver function The normal range of AST is 0 to 45 U/L. ALT (alanine aminotransferase), which was previously called SGPT, is more specific for liver damage. The normal range of ALT is 0 to 45 U/L. ALP (alkaline phosphatase) is elevated in many types of liver disease, but also in non-liver related diseases.

Elevated transaminases In medicine, the presence of elevated transaminases, commonly the transaminases alanine transaminase and aspartate transaminase, may be an indicator of liver damage. Other terms employed include transaminasemia and transaminitis, although some sources consider the latter pathologically meaningless. Normal ranges for both ALT and AST are 8-40 U/L with mild transaminesemia noted to the upward numerical limit of 250 U/L. Drug-induced increases such as that found with the use of anti-tuberculosis ag

- This is particularly important if your TSH test results are normal, but you have symptoms. There are several controversies about the TSH test and what it means. Among endocrinologists, there is a controversy as to what the TSH reference range should be. Typically, it runs from around .4/.5 to 4.5 or so.

- Reference values for aPTT vary among laboratories, but generally range between 25 and 38 seconds. The aPTT of a newborn will usually be prolonged and may be up to 55 seconds at birth.It decreases to the adult range by 6 months of age. (Note: each lab has its own reference values based upon the equipment and reagents used.). The aPTT is the most commonly used test to monitor heparin therapy.The therapeutic goal for a patient being anticoagulated with heparin, is an aPTT approximately 1.5 to 2.5 times the mean normal value.Note: each lab has its own reference values based upon the equipment and reagents used.).

- If AST and ALT levels are normal (< 50 IU/L) and the acetaminophen level is < 10 μg/mL, significant hepatotoxicity is very unlikely. If AST and ALT levels are normal but the acetaminophen level is ≥ 10 μg/mL, significant hepatotoxicity is possible; AST and ALT levels are remeasured after 24 h.

Liver Tests AST – (aspartate aminotransferase), which was previously called SGOT. This enzyme can also be elevated in heart and muscular diseases and is not liver specific. Normal range of AST is 5-45 U/L. ALT – (alanine aminotransferase), which was previously called SGPT and is more specific for liver damage. Normal range of ALT is 5-45 U/L.

Understanding the TSH Test and Its Controversies The TSH Reference Range. As of 2017, at most laboratories in the U.S. the official reference range for the TSH test runs from approximately 0.5 to 4.5 or 5.0 (mIU/L). A patient whose TSH level is within the reference range is referred to as euthyroid, and is considered to have normal thyroid function. The reference range—also sometimes called the normal range—is an important part of your overall thyroid diagnosis and treatment program, because the conventional endocrinology world considers it to be key to diagnosis and management of thyroid function.

What Is the Normal Range for Liver Enzymes? What is the normal range for ALT and AST liver tests? Normal ranges for ALT liver tests are 7 to 55 units per liter and 8 to 48 units per liter for AST, states Mayo Clinic. These ranges are established for adult men and may differ with women and children.

What is considered a normal range for PSA test? The PSA test measures the level of prostate specific antigen in your blood. PSA is an enzyme that is produced by a man's prostate gland. The normal range for the PSA test is less than 4.0 nanograms per milliliter (ng/mL) in most men.If you are over 40 years old and have a family history of prostate disease or if you are an African-American man over 40 years old, some doctors suggest that a level higher than 2.5 ng/mL should be checked with more tests.est Answer: The normal value for total PSA has been set at less than 4.0 ng/ml (nanograms per milliliter of blood). There are some that feel that this level should be lowered to 2.5 ng/ml in order to detect more cases of prostate cancer.

Liver Blood Tests Normal levels of AST and ALT may slightly vary depending on the individual laboratory's reference values. Typically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter. Mild elevations are generally considered to be 2-3 times higher than the normal range.ypically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter.

- As of late 2016, at most laboratories in the U.S., the official reference range for the Thyroid Stimulating Hormone (TSH) blood test runs from approximately 0.5 to 4.5/5.0. The reference range -- also sometimes called the normal range -- is an important part of the complete picture of thyroid diagnosis and treatment. In fact,the entire TSH test as diagnostic and management tool depends on this validity. That is because the reference range is what determines -- for the majority of physicians -- whether or not a thyroid disease or condition is even diagnosed at all, much less treated, and when diagnosed, how it is treated.

Reference Range Information Normal range was determined by testing 271 male and female adult healthy blood donors at UCSF. Pediatric patients will use adult range due to comparable ranges between UCSF's normal study and Soldin, Steven J.
