Thromboelastography (TEG) Test: Clot Strength, Bleeding Risk, Clotting Function, and Results
Thromboelastography, often shortened to TEG, is a blood clotting test that shows how a clot forms, how strong it becomes, and whether it breaks...
von Willebrand Disease Panel: vWF Antigen, vWF Activity, Factor VIII, Bleeding Risk, and Results
A von Willebrand disease panel checks whether your blood has enough working von Willebrand factor, the clotting protein that helps platelets stick to damaged...
von Willebrand Factor (vWF) Activity Test: Low vWF Activity, Bleeding Risk, Normal Range, and Results
The von Willebrand factor activity test measures how well von Willebrand factor helps platelets stick to an injured blood vessel and start a clot....
von Willebrand Factor (vWF) Antigen Test Normal Range: Reference Values and Meaning

Aldolase and CK: Interpreting Muscle Enzyme Results
Aldolase and creatine kinase, usually called CK, are blood enzymes that can rise when muscle cells are irritated, inflamed, injured, or breaking down. CK...
Aldolase Blood Test: High Aldolase, Muscle Disease, Normal Range, and Results
The aldolase blood test measures an enzyme found mainly in skeletal muscle, liver, and other tissues. In everyday practice, doctors use it most often...
Aspartate Aminotransferase (AST) Test: High AST, Muscle Injury, Heart Injury, and Results

BNP and NT-proBNP: Interpreting Heart Failure Markers Without Overdoing It
BNP and NT-proBNP are blood tests that help show whether the heart is under pressure from excess stretch, fluid overload, or heart failure. They...
BNP vs NT-proBNP: What Is the Difference?
BNP and NT-proBNP are blood tests that help show whether the heart is under strain, especially when heart failure is suspected. They are closely...
B-Type Natriuretic Peptide (BNP) Test: High BNP, Heart Failure, Normal Range, and Results
The BNP test measures a hormone released by the heart when its chambers stretch from extra pressure or fluid. It is most often used...

CK, AST, and LDH: Interpreting Muscle vs Liver Injury Patterns
Creatine kinase (CK), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) can rise after muscle damage, liver injury, blood cell breakdown, intense exercise, infection, trauma,...
CK-MB and Troponin: Interpreting Cardiac Enzyme Patterns
CK-MB and troponin are blood markers released when heart muscle cells are injured, but they do not carry the same diagnostic weight. Troponin I...
CK-MB Blood Test: High CK-MB, Heart Muscle Injury, Normal Range, and Results
The CK-MB blood test measures a specific form of creatine kinase, an enzyme released when muscle cells are injured. CK-MB was once one of...
CK-MB Relative Index Test: Heart Injury, Skeletal Muscle Damage, CK-MB Ratio, and Results
The CK-MB relative index is a calculated result that compares CK-MB, a form of creatine kinase found in heart muscle and smaller amounts of...
Copeptin Blood Test: Heart Attack Rule-Out Marker, Stress Response, and Results
