All Liver Tests

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-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 ANA Screen IFA with Reflex to Titer and Pattern Test detects antinuclear antibodies in blood to evaluate autoimmune activity. If positive, further testing identifies antibody concentration (titer) and fluorescence pattern, helping diagnose conditions like lupus, rheumatoid arthritis, or Sjögren’s syndrome. Doctors order this test to investigate symptoms such as joint pain, fatigue, rash, or swelling and to guide treatment for autoimmune and connective tissue disorders.

The ANA IFA Panel Comprehensive screens for autoimmune disorders by detecting antinuclear antibodies and specific markers including dsDNA, Sm, Sm/RNP, Scl-70, and Sjögren’s SS-A/SS-B. Doctors order this panel for patients with joint pain, rash, fatigue, or suspected lupus, scleroderma, or Sjögren’s syndrome. Results provide critical insight into autoimmune activity, helping confirm diagnosis, monitor disease progression, and guide treatment decisions.

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 B-Type Natriuretic Peptide (BNP) Test measures BNP levels in blood to help diagnose and monitor heart failure and other cardiac conditions. High levels suggest the heart is under stress, often from congestive heart failure, hypertension, or heart disease. Doctors order this test for patients with shortness of breath, fatigue, or swelling. Results provide critical insight into heart function, guiding treatment and monitoring response to therapy.

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 BUN Creatinine Ratio Test compares blood urea nitrogen (BUN) to creatinine levels to assess kidney function and hydration status. A high ratio may indicate dehydration, gastrointestinal bleeding, or high protein intake, while a low ratio can suggest liver disease or malnutrition. Doctors order this test with kidney panels to evaluate fatigue, swelling, or abnormal lab results. Results help diagnose renal issues and guide treatment planning.

The C-Reactive Protein (CRP) Test measures CRP levels in blood to detect inflammation in the body. Elevated CRP may indicate infections, autoimmune disorders, or chronic diseases such as arthritis, cardiovascular disease, or inflammatory bowel disease. Doctors use this test to assess acute illness, monitor treatment response, and evaluate risk for heart disease. The CRP test provides key insight into inflammation, immune health, and overall wellness.

The CA 19-9 Test measures levels of carbohydrate antigen 19-9 in blood, a tumor marker often elevated in pancreatic cancer and sometimes in bile duct, colorectal, or liver cancers. While not used alone for diagnosis, it helps monitor treatment, track disease progression, and detect recurrence. Elevated CA 19-9 may also occur in noncancerous conditions. Doctors use this test to support cancer management and guide therapy decisions.

The Cardio IQ™ Fibrinogen Antigen Test evaluates fibrinogen concentration, a key protein that influences clotting and cardiovascular disease risk. It provides insight into vascular inflammation, atherosclerosis, and thrombotic events. This test helps identify factors that contribute to stroke, coronary artery disease, and systemic vascular complications, offering valuable information for assessing overall cardiovascular health.

The Cardio IQ™ Triglycerides Test measures triglyceride levels in the blood, an important marker of lipid metabolism and cardiovascular health. Elevated triglycerides are linked to increased risk of heart disease, pancreatitis, and metabolic syndrome. Physicians use this test to assess risk factors, monitor therapy response, and guide lifestyle or treatment decisions, often as part of a broader lipid or heart health evaluation.

The Cardio IQ Vitamin D test, also known as a 25-hydroxy vitamin D test, measures the levels of total vitamin D in the blood, including both vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). It provides information about an individual's overall vitamin D status.

The Catecholamines Fractionated Plasma Test measures plasma levels of dopamine, epinephrine, and norepinephrine, hormones that regulate stress response, blood pressure, and heart rate. Elevated levels may indicate pheochromocytoma, paraganglioma, or other adrenal and nervous system disorders. Doctors use this test to investigate symptoms like hypertension, headaches, sweating, or palpitations, and to monitor treatment of adrenal tumors.

The CEA Test measures carcinoembryonic antigen levels in blood, a protein that may be elevated in certain cancers, especially colorectal, pancreatic, lung, breast, or ovarian cancer. It is not used alone for diagnosis but helps monitor cancer treatment, detect recurrence, and track disease progression. Elevated CEA can also occur in noncancerous conditions. Doctors use this test to support therapy decisions and provide insight into cancer management.

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.
