Blood investigation, or blood testing, refers to the analysis of a blood sample to assess overall health and detect a wide range of disorders, such as infections, anemia, immune system disorders, and other diseases.
Purpose: Evaluates overall health and detects a variety of disorders, such as anemia, infection, and many other diseases. Components: Red Blood Cell Count (RBC): Measures the number of red blood cells in the blood. Hemoglobin (Hb): The protein in red blood cells that carries oxygen. Hematocrit (Hct): The proportion of blood that consists of red blood cells. White Blood Cell Count (WBC):Measures the number of white blood cells, which fight infection. Platelet Count: Measures the number of platelets, which help with blood clotting.
Purpose: Measures various chemicals in the blood to provide information about the body's metabolism, including kidney function, blood sugar levels, and electrolyte and fluid balance. Components: Glucose: Blood sugar level. Calcium: Essential for bone health and muscle function. Electrolytes: Including sodium, potassium, carbon dioxide (bicarbonate), and chloride. Kidney Function: Blood urea nitrogen (BUN) and creatinine levels.
Purpose:Assesses the risk of cardiovascular diseases by measuring cholesterol and triglycerides in the blood. Components: Total Cholesterol:Overall cholesterol level in the blood. Low-Density Lipoprotein (LDL) Cholesterol: "Bad" cholesterol, which can build up in arteries. High-Density Lipoprotein (HDL) Cholesterol: "Good" cholesterol, which helps remove LDL from the bloodstream. Triglycerides: A type of fat in the blood.
Purpose: Evaluates the health of the liver by measuring the levels of enzymes and proteins in the blood. Components: Alanine Aminotransferase (ALT):An enzyme found in the liver. Aspartate Aminotransferase (AST): An enzyme found in the liver and other tissues. Alkaline Phosphatase (ALP): An enzyme related to the bile ducts. Bilirubin: A byproduct of red blood cell breakdown. Albumin and Total Protein: Essential proteins produced by the liver.
Purpose: Assesses how well the kidneys are working by measuring levels of substances in the blood. Components: Blood Urea Nitrogen (BUN): A waste product filtered out of the blood by the kidneys. Creatinine: A waste product produced by muscle metabolism and filtered out by the kidneys. Estimated Glomerular Filtration Rate (eGFR): Estimates the rate of blood flow through the kidneys.
Purpose: Measures the amount of glucose (sugar) in the blood to diagnose and monitor diabetes. Components: Fasting Blood Glucose: Measures blood sugar after an overnight fast. HbA1c (Hemoglobin A1c):Reflects average blood glucose levels over the past 2-3 months.
Purpose: Measures specific enzymes in the blood to diagnose conditions such as heart attack, liver disease, and muscle damage. Components: Troponin: Released into the blood during a heart attack. Creatine Kinase (CK): Enzyme released from damaged muscle. Lactate Dehydrogenase (LDH): Enzyme involved in energy production.
Purpose: Measures the level of CRP, a protein produced by the liver in response to inflammation. Indications: Helps diagnose and monitor conditions such as infections, chronic inflammatory diseases, and cardiovascular diseases.
Purpose: Measures how quickly red blood cells settle at the bottom of a test tube; a faster rate may indicate inflammation. Indications: Helps diagnose conditions such as infections, autoimmune diseases, and cancers.
