A D-dimer test measures the amount of D-dimer, a protein fragment formed when blood clots break down, in the blood. This test is primarily used to help rule out blood clots in conditions like deep vein thrombosis (DVT) and pulmonary embolism (PE). An elevated D-dimer level suggests the possibility of a blood clot, but further testing is usually required to confirm the diagnosis.

C-Reactive Protein (CRP) is a blood test that measures the level of CRP, a protein produced by the liver in response to inflammation. It's a nonspecific marker of inflammation, meaning it can be elevated in various conditions, including infections, autoimmune diseases, and heart disease. While CRP doesn't diagnose a specific condition, it can help monitor disease activity, assess the risk of heart attack or stroke, and guide treatment decisions.

LDH is an enzyme found in various tissues throughout the body, including the heart, liver, skeletal muscle, kidneys, and red blood cells. It is involved in the breakdown of glucose for energy production. When tissues are damaged or diseased, LDH levels in the blood can increase. Elevated LDH levels can be a sign of conditions such as heart attacks, liver disease, hemolytic anemia, muscle damage, and certain cancers. However, it is important to note that elevated LDH levels alone may not be enough to diagnose a specific condition, and further testing may be necessary to determine the underlying cause.

Liver function tests are a group of blood tests that evaluate the health and function of your liver. They measure levels of various enzymes, proteins, and substances produced by the liver. Abnormal results can indicate liver damage, inflammation, or disease. Common liver function tests include ALT, AST, alkaline phosphatase, bilirubin, and albumin. These tests help diagnose conditions like hepatitis, cirrhosis, and fatty liver disease, as well as monitor liver health in people with chronic conditions.

Kidney Function Tests (KFTs) evaluate how well your kidneys are filtering waste products from your blood. These tests typically include measurements of creatinine, blood urea nitrogen (BUN), and electrolytes. By assessing these values, healthcare providers can identify potential kidney problems, monitor kidney disease progression, and evaluate the effectiveness of treatment. KFTs are crucial for individuals with diabetes, high blood pressure, or a family history of kidney disease.
