Electrolytes and Glucose
Electrolytes and glucose are vital for maintaining fluid balance, nerve function, and energy production. Key electrolytes include Sodium (136-145 mEq/L), Potassium (3.5-5.0 mEq/L), Calcium (9.0-10.5 mg/dL), Magnesium (1.3-2.1 mEq/L), and Glucose (70-105 mg/dL fasting), essential for assessing imbalances and metabolic conditions.
2.1 Sodium (136-145 mEq/L)
Sodium (136-145 mEq/L) regulates fluid balance and nerve/muscle function. Deviations indicate potential neurological or cardiac complications, requiring close monitoring and interventions to restore balance and prevent complications like seizures or arrhythmias.
2.2 Potassium (3.5-5.0 mEq/L)
Potassium (3.5-5.0 mEq/L) is crucial for cardiac function, muscle contraction, and nerve impulses. Imbalances can cause arrhythmias or muscle weakness, requiring prompt intervention to maintain homeostasis and prevent complications, especially in cardiac patients.
2.3 Calcium (9.0-10.5 mg/dL)
Calcium levels (9.0-10.5 mg/dL) are vital for bone health, muscle function, and nerve transmission. Abnormal levels can lead to symptoms like tetany or bone pain, necessitating careful monitoring to ensure proper physiological functions and prevent metabolic disorders.
2.4 Magnesium (1.3-2.1 mEq/L)
Magnesium levels (1.3-2.1 mEq/L) are essential for muscle and nerve function, blood glucose control, and blood pressure regulation. Deficiencies can cause muscle cramps, fatigue, and cardiac arrhythmias, while excess levels may lead to respiratory depression or cardiac arrest, requiring prompt intervention.
2.5 Glucose (70-105 mg/dL fasting)
Glucose (70-105 mg/dL fasting) is a critical indicator of metabolic health, reflecting blood sugar regulation. Monitoring fasting glucose levels helps diagnose and manage conditions like diabetes, with deviations indicating potential hypo- or hyperglycemia, affecting energy production and overall bodily functions.
Hematology
Hematology assesses blood components, including red and white blood cell counts, hemoglobin, hematocrit, and platelets. These tests help diagnose anemia, infections, and bleeding disorders, crucial for patient care.
3.1 Complete Blood Count (CBC)
A CBC measures various blood components, including red and white blood cell counts, hemoglobin, hematocrit, and platelets. Abnormal values can indicate conditions like anemia, infection, or bleeding disorders, aiding in early diagnosis and targeted treatment plans for patients.

Alanine aminotransferase (ALT) is a liver enzyme; elevated levels may indicate liver damage or disease, such as hepatitis or cirrhosis. Monitoring ALT helps assess liver health and diagnose conditions requiring timely intervention.
7.2 AST (0-35 U/L)
Aspartate aminotransferase (AST) is a liver enzyme found in various tissues, including the heart and muscles. Elevated AST levels may indicate liver damage, cardiac issues, or muscle disorders, aiding in the diagnosis of conditions like hepatitis or myocardial infarction.
7.3 ALP (30-120 U/L)
Alkaline phosphatase (ALP) measures enzyme levels in the liver, bones, and bile ducts. Elevated ALP may indicate liver conditions like cholestasis or bone disorders such as Paget’s disease. Monitoring ALP aids in diagnosing and managing these conditions effectively.
7.4 Total Bilirubin (0.3-1.0 mg/dL)
Total bilirubin measures bilirubin levels, a breakdown product of hemoglobin. Elevated levels may indicate liver dysfunction, bile duct issues, or hemolytic anemia. Monitoring bilirubin aids in diagnosing conditions like jaundice and assessing liver health, guiding timely interventions for optimal patient care.
Coagulation
Coagulation studies assess the body’s blood-clotting mechanisms, essential for diagnosing bleeding disorders and monitoring anticoagulant therapy, ensuring proper patient care and treatment plans are effectively implemented.
8.1 Prothrombin Time (PT) (10-14 seconds)
Prothrombin Time (PT) measures the time it takes for blood to clot, reflecting the integrity of the extrinsic coagulation pathway. It helps assess clotting factor deficiencies and monitor warfarin therapy. Elevated PT indicates prolonged clotting, suggesting bleeding risks or therapeutic effects.
8.2 Partial Thromboplastin Time (PTT) (25-37 seconds)
PTT evaluates the intrinsic coagulation pathway, measuring clotting time. Elevated levels suggest bleeding disorders, clotting factor deficiencies, or heparin therapy effects. Decreased PTT may indicate clotting risks or conditions like disseminated intravascular coagulation (DIC). Monitoring PTT is vital for patient care and treatment adjustments.
8.3 INR (0.9-1.1)
INR measures blood clotting, with normal range 0.9-1.1. Elevated INR indicates increased bleeding risk, often due to warfarin therapy or clotting disorders. Low INR suggests reduced anticoagulation effectiveness. Monitoring INR is crucial for managing anticoagulant therapy and preventing complications.
8.4 Fibrinogen (200-400 mg/dL)
Fibrinogen, a glycoprotein, plays a key role in blood clotting. Normal levels range from 200-400 mg/dL. Elevated levels may indicate inflammation or cancer, while low levels suggest bleeding disorders or liver disease. Monitoring fibrinogen aids in assessing coagulation status and patient care.
Blood Lipid Levels
Blood lipid levels are crucial markers for cardiovascular health. They include total cholesterol, LDL, HDL, and triglycerides, with normal ranges essential for assessing heart disease risks and managing conditions effectively.
9.1 Total Cholesterol (<200 mg/dL)
Total cholesterol measures all cholesterol in blood, including LDL and HDL. Levels below 200 mg/dL are considered optimal, reducing cardiovascular risks. Elevated levels may indicate hyperlipidemia, requiring lifestyle changes or medication to manage effectively and prevent complications.
9.2 LDL (<100 mg/dL)
LDL, or “bad” cholesterol, should ideally be below 100 mg/dL to minimize cardiovascular risks. Elevated LDL levels can lead to plaque buildup in arteries, increasing the risk of heart disease and stroke. Monitoring and managing LDL is crucial for maintaining heart health.
9.3 HDL (>40 mg/dL)
HDL, known as “good” cholesterol, should be above 40 mg/dL for adults. Higher levels help remove excess cholesterol from cells, reducing cardiovascular risks. HDL plays a key role in maintaining heart health by protecting against artery blockages and promoting overall well-being.
9.4 Triglycerides (<150 mg/dL)
Triglycerides measure fat in the blood, with normal levels below 150 mg/dL. Elevated levels are linked to cardiovascular risks and pancreatitis. Managing through diet, exercise, and weight loss is crucial for maintaining healthy levels and overall heart health.
