Hepatic Function

The ALT Test measures alanine aminotransferase, an enzyme mainly found in the liver. Elevated ALT may indicate liver damage from hepatitis, fatty liver disease, cirrhosis, alcohol use, or medication effects. Doctors order this test to evaluate symptoms such as fatigue, abdominal pain, or jaundice and often pair it with AST for accurate liver assessment. Results provide essential insight into liver health, enzyme activity, and overall metabolic function.

The Ammonia Plasma Test measures ammonia levels in blood to evaluate liver function and metabolic health. Elevated ammonia may result from liver disease, cirrhosis, Reye’s syndrome, or urea cycle disorders, causing confusion or altered mental status. Doctors order this test for patients with unexplained behavioral changes, lethargy, or suspected hepatic encephalopathy. Results provide key insight into liver function, metabolic disorders, and treatment monitoring.

The ANCA Screen with Reflex to ANCA Titer detects antineutrophil cytoplasmic antibodies, often linked to autoimmune vasculitis such as granulomatosis with polyangiitis and microscopic polyangiitis. If the screen is positive, a titer is performed to measure antibody levels for greater diagnostic accuracy. Doctors use this test to evaluate unexplained inflammation, kidney or lung issues, and guide treatment decisions in autoimmune and systemic vasculitis care.

The AST Test measures aspartate aminotransferase, an enzyme found in the liver, heart, muscles, and other tissues. Elevated AST may indicate liver disease, heart attack, muscle injury, or other organ damage. Doctors order this test to evaluate symptoms such as fatigue, weakness, or jaundice and often pair it with ALT for accurate liver assessment. Results provide key insight into liver function, muscle health, and overall metabolic balance.

The Bile Acids Fractionated and Total Test measures both individual bile acid fractions and total bile acid concentration to evaluate liver function, bile flow, and metabolic integrity. This analysis helps detect cholestasis, hepatocellular injury, or impaired bile acid metabolism, supporting assessment of liver disorders, intrahepatic cholestasis of pregnancy, and other hepatobiliary conditions.

The Bilirubin Direct Test measures conjugated bilirubin in the blood to assess liver function and bile duct health. Elevated levels may indicate hepatitis, cirrhosis, gallstones, or bile duct obstruction, while low levels are generally normal. Doctors order this test for patients with jaundice, fatigue, or suspected liver disease. Results help diagnose and monitor liver disorders, guide treatment decisions, and evaluate overall hepatic and biliary health.

The Fractionated Bilirubin Test separates total bilirubin into direct and indirect forms to assess liver and blood health. Elevated direct bilirubin may point to hepatitis, cirrhosis, or bile duct obstruction, while elevated indirect levels can signal hemolytic anemia or inherited disorders. Doctors order this test for jaundice, anemia, or suspected liver conditions. Results help guide diagnosis, treatment, and monitoring of liver and blood disorders.

The Bilirubin Total Test measures the overall level of bilirubin in blood to assess liver function, red blood cell breakdown, and bile duct health. Elevated bilirubin may cause jaundice and indicate hepatitis, cirrhosis, gallstones, or hemolytic anemia. Doctors order this test for patients with yellowing skin, fatigue, or abnormal liver results. Results provide essential insight into liver disease, blood disorders, and bile flow problems, guiding diagnosis and treatment.

The Neonatal Bilirubin Total Test evaluates the concentration of bilirubin in newborn blood, an important marker of liver processing and red blood cell breakdown. High bilirubin may cause neonatal jaundice and, in severe cases, lead to neurological complications. This test supports early detection, monitoring of bilirubin trends, and assessment of infant health during the newborn period.

The Ceruloplasmin Test measures levels of ceruloplasmin, a copper-carrying protein made in the liver, to evaluate copper metabolism and related disorders. Low levels may indicate Wilson’s disease, Menkes disease, or severe liver disease, while high levels may suggest inflammation or pregnancy. Doctors order this test for patients with liver problems, neurological symptoms, or abnormal copper levels. Results help diagnose metabolic disorders and guide treatment.

The Complete Blood Count with Differential and Platelets Test is a comprehensive blood test that checks red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. The differential analyzes types of white blood cells to detect infections, anemia, clotting abnormalities, immune conditions, and certain cancers. This essential test is often ordered for routine health exams, diagnosis, and monitoring treatment progress.

The Copper Micronutrient Plasma Test measures copper levels in the blood to evaluate nutritional status and detect deficiencies or excess. Copper is essential for red blood cell formation, connective tissue health, energy production, and nervous and immune system function. This test helps identify imbalances from poor diet, malabsorption, or toxicity, supporting diagnosis and management of overall health.

Patient must be 18 years of age or older.

The Copper Test measures copper levels in blood to evaluate nutritional status, liver function, and metabolic health. Abnormal levels may indicate Wilson’s disease, Menkes disease, liver disorders, or malnutrition. Both deficiency and excess copper can affect nervous system, immune function, and energy metabolism. Doctors use this test to investigate unexplained symptoms, monitor treatment, or assess copper-related disorders, providing key insight into overall health.

The DCP Test detects des-gamma-carboxy prothrombin, an abnormal form of prothrombin linked to hepatocellular carcinoma and other liver disorders. Elevated levels may reflect tumor activity, chronic liver disease, or cirrhosis. This test provides valuable information for assessing liver function, monitoring cancer progression, and evaluating systemic health in patients with hepatic disease.

The Ferritin Test measures ferritin, a protein that stores iron in the body, to evaluate iron levels and detect deficiency or overload. It helps diagnose anemia, iron deficiency, hemochromatosis, and chronic disease-related inflammation. Doctors often order the ferritin test to investigate fatigue, weakness, or unexplained symptoms. It is also used to monitor iron supplementation, treatment effectiveness, and overall iron metabolism health.

The GGT Test measures gamma-glutamyl transferase, an enzyme found in the liver and bile ducts, to evaluate liver health. Elevated GGT may indicate liver disease, bile duct obstruction, alcohol use, or medication side effects. Doctors order this test to investigate symptoms like fatigue, jaundice, dark urine, or abdominal pain and to monitor liver damage. It is often performed with other liver tests to provide a complete picture of liver and bile duct function.

The Hepatitis A Antibody Total Test is a qualitative test that detects antibodies to hepatitis A virus (HAV) and reports results as Reactive or Non-Reactive. It does not distinguish between IgM and IgG antibodies. A reactive result may indicate past infection or immunity from vaccination, while a non-reactive result suggests no prior exposure. Doctors use this test to assess immune status, guide vaccination decisions, and evaluate risk of hepatitis A infection.

The Hepatitis B Core IgM Antibody Test is a qualitative test that detects IgM antibodies to the hepatitis B core antigen (anti-HBc IgM) and reports results as Reactive or Non-Reactive. A reactive result indicates a recent or acute hepatitis B infection, while a non-reactive result suggests no active infection. Doctors order this test to confirm acute hepatitis B in patients with symptoms such as jaundice, fatigue, fever, or abdominal pain and to guide treatment and monitoring.

The Hepatitis B Surface Antigen (HBsAg) Test with Reflex to Confirmation screens for hepatitis B surface antigen in blood and, if reactive, automatically performs confirmatory testing. A reactive confirmed result indicates an active hepatitis B infection, while a non-reactive result shows no infection. Doctors use this test to diagnose acute or chronic hepatitis B, investigate abnormal liver tests, and guide treatment, monitoring, and infection control decisions.

The Hepatitis C Antibody with HCV RNA Quantitative PCR test is a comprehensive diagnostic test used to detect and confirm the presence of the Hepatitis C virus (HCV) in the blood. It combines the initial screening for HCV antibodies with a quantitative polymerase chain reaction (PCR) test to measure the viral load.

 The Hepatitis C Antibody & Liver Function Panel is a comprehensive diagnostic tool used to detect the presence of hepatitis C virus (HCV) antibodies and assess liver function. This panel includes the Hepatitis C Antibody with Reflex to Quantitative HCV RNA PCR test, along with a series of liver function tests: Albumin, Albumin/Globulin Ratio, Alkaline Phosphatase, Alanine Transaminase (ALT), Aspartate Aminotransferase (AST), Bilirubin Direct, Bilirubin Indirect, Bilirubin Total, Globulin, and Protein Total. This panel is crucial for diagnosing HCV infection and evaluating the liver's health and functionality.

The Hepatitis C Viral RNA Quantitative Test measures the amount of hepatitis C virus (HCV) RNA in blood to determine viral load. This test confirms active infection, evaluates disease severity, and monitors response to antiviral therapy. High viral load indicates significant viral replication, while lower or undetectable levels suggest effective treatment or controlled infection. Doctors use this test to guide therapy, track progress, and manage long-term liver health.

The General Hepatitis Panel Test screens for multiple hepatitis infections in one order. It includes Hepatitis A Antibody Total, Hepatitis B Surface Antibody Qualitative, Hepatitis B Surface Antigen with Reflex to Confirmation, Hepatitis B Core Antibody Total, and Hepatitis C Antibody with Reflex to RNA PCR. Doctors use this panel to detect past exposure, confirm active or chronic infection, guide treatment, and support liver health monitoring.

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.
