Hepatic Function

The Albumin Test measures albumin, the main protein made by the liver that maintains fluid balance and transports hormones, vitamins, and medications. Low albumin may indicate liver disease, kidney problems, malnutrition, or chronic inflammation, while high levels may reflect dehydration. Doctors order this test to evaluate swelling, fatigue, or abnormal labs. Results provide key insight into nutritional status, liver and kidney function, and overall metabolic health.

The Alkaline Phosphatase Isoenzymes Test measures different forms of alkaline phosphatase (ALP) in the blood to determine their source, such as liver, bone, intestine, or placenta. Doctors use this test to evaluate abnormal ALP results, identify liver disease, bile duct obstruction, bone disorders like Paget’s disease, or certain cancers. It helps distinguish between conditions and guides accurate diagnosis and treatment planning.

The ALP Test measures alkaline phosphatase enzyme levels in blood to evaluate liver, bone, and bile duct health. High ALP may indicate liver disease, bile duct obstruction, bone disorders, or certain cancers, while low levels may suggest malnutrition or deficiency. Doctors order this test to investigate symptoms like fatigue, abdominal pain, or bone pain and often pair it with other liver function tests. Results provide key insight into metabolic and organ health.

The Alpha-1-Antitrypsin Quantitative Test measures levels of alpha-1-antitrypsin (AAT), a protein that protects the lungs and liver from damage. Low levels may indicate alpha-1-antitrypsin deficiency, a genetic disorder linked to emphysema, COPD, and liver disease. Doctors use this test to investigate unexplained lung or liver problems, confirm hereditary AAT deficiency, and guide treatment or monitoring strategies for long-term health management.

The Alpha-1 Antitrypsin Random Feces Test measures levels of alpha-1 antitrypsin, a protein that normally remains in the bloodstream. Elevated amounts in stool suggest protein-losing enteropathy, intestinal inflammation, or gastrointestinal conditions that impair absorption. By evaluating protein loss through the digestive tract, this test helps assess intestinal integrity and overall digestive health.

The Alpha-Fetoprotein (AFP) and AFP-L3 Test measures total AFP and the AFP-L3 fraction, which is more specific for liver cancer risk. Elevated AFP may indicate liver disease, germ cell tumors, or hepatitis, while AFP-L3 is strongly associated with hepatocellular carcinoma (HCC). Doctors order this test to assess liver function, screen high-risk patients, and monitor cancer treatment. Results provide critical insight into liver health and cancer detection.

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 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 Comprehensive Metabolic Panel (CMP) Test measures 21 markers to assess metabolic health, liver and kidney function, and electrolyte balance. It includes glucose, calcium, sodium, potassium, chloride, CO2, albumin, globulin, A/G ratio, total protein, bilirubin, ALP, AST, ALT, BUN, creatinine, BUN/creatinine ratio, and eGFR. The CMP helps detect diabetes, liver or kidney disease, and supports routine screening and chronic condition monitoring.

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.
