The five main blood tests commonly performed in healthcare settings include: 1. Complete Blood Count (CBC): Assesses red and white blood cells, hemoglobin levels, platelets, and other parameters. 2. Basic Metabolic Panel (BMP): Measures electrolytes, glucose, kidney function, and liver enzymes. 3. Lipid Panel: Evaluates cholesterol and triglyceride levels, important for assessing cardiovascular health. 4. Liver Function Test (LFT): Checks liver enzymes, bilirubin, and proteins to assess liver health. 5. Hemoglobin A1c (HbA1c): Monitors long-term blood sugar control in individuals with diabetes. These tests provide valuable information about overall health, organ function, and potential underlying conditions. However, specific tests may vary depending on individual needs and healthcare provider recommendations.
