Complete Blood Count (CBC): A blood test measuring red blood cells, hemoglobin, hematocrit, white blood cells, and platelets to evaluate overall health and detect disorders like anemia, infection, or bleeding issues.
Blood Glucose: The amount of sugar in the blood; normal fasting range is 70–99 mg/dL. Elevated levels indicate hyperglycemia, often associated with diabetes mellitus.
Electrolytes (Sodium, Potassium, Chloride, Bicarbonate): Minerals vital for nerve function, fluid balance, and acid-base regulation. Imbalances can cause serious cardiac and neurological issues.
Coagulation Tests (PT, INR, aPTT): Assess blood clotting ability. PT/INR monitor warfarin therapy; aPTT monitors heparin therapy. Abnormalities may indicate bleeding risk or clotting disorders.
Liver Function Tests (ALT, AST, ALP, Bilirubin): Measure liver enzymes and bilirubin to detect liver inflammation, damage, or cholestasis.
Thyroid Function Tests (TSH, Free T4, T3): Evaluate thyroid gland activity. Abnormal levels indicate hypo- or hyperthyroidism.
