The purpose of a Complete Blood Count (CBC) is to evaluate overall health, screen for diseases, and investigate symptoms like fatigue, fever, or bruising. It measures the types and numbers of cells in your blood, specifically red blood cells (for oxygen), white blood cells (for immunity), and platelets (for clotting)
Red Blood Cells (RBCs) & Hemoglobin: These carry oxygen throughout your body. Abnormal counts can indicate anemia or other blood disorders.
White Blood Cells (WBCs): These fight infections. High levels usually indicate an infection or inflammation, while low levels can suggest bone marrow issues or immune disorders.
Platelets: These help your blood to clot to prevent excessive bleeding. Counts outside the standard range can indicate bleeding or clotting disorders.
The primary purpose of a liver function test (LFT) is to evaluate overall liver health, detect inflammation, and locate potential damage or disease. It achieves this by measuring blood levels of specific proteins, liver enzymes, and waste products (like bilirubin) that the liver produces or processes.
- Liver Enzymes (ALT, AST, ALP, GGT): Elevated levels usually indicate inflammation or damage to liver cells.
- Proteins (Albumin and Total Protein): Measures the liver’s ability to produce essential proteins required for bodily functions.
- Bilirubin: Measures a waste product created by the breakdown of red blood cells. High levels often point to impaired liver or bile duct function.
The purpose of a kidney function test (or renal panel) is to assess how effectively your kidneys are cleaning your blood, balancing bodily fluids, and maintaining essential mineral levels. These evaluations are primarily used to detect early signs of kidney disease, monitor existing conditions, and evaluate the effects of medications.
