Normal Lab Values Cheat Sheet for NCLEX: Lab Values from A to Z As a nurse, it is important to know the normal lab values for the different tests that patients undergo. Normal lab values are used as a guide to interpret the results of laboratory tests. These values help us to determine if a patient’s test results are normal or if they have an abnormality that requires further investigation. Here is a comprehensive cheat sheet that lists the normal lab values for commonly ordered tests. These values are important to know for the NCLEX exam and for clinical practice. Complete Blood Count (CBC) - Hemoglobin (Hgb): 12-16 g/dL - Hematocrit (Hct): 36%-48% - Red Blood Cells (RBC): 4.5 - 5.5 million/mm3 - White Blood Cells (WBC): 4,500 - 11,000/mm3 - Platelets (Plt): 150,000 - 400,000/mm3 Basic Metabolic Panel (BMP) - Sodium (Na): 135 - 145 mmol/L - Potassium (K): 3.5 - 5.1 mmol/L - Calcium (Ca): 8.5 - 10.2 mg/dL - Chloride (Cl): 96 - 106 mmol/L - Bicarbonate (HCO3): 22 - 28 mmol/L - Blood Urea Nitrogen (BUN): 7 - 20 mg/dL - Creatinine (Cr): 0.6 - 1.2 mg/dL - Glucose (fasting): 70 - 99 mg/dL Comprehensive Metabolic Panel (CMP) - Albumin: 3.5 - 5.0 g/dL - Alkaline Phosphatase (ALP): 44 - 147 U/L - Alanine Aminotransferase (ALT): 0 - 35 U/L - Aspartate Aminotransferase (AST): 0 - 35 U/L - Total Bilirubin (Tbili): 0.1 - 1.0 mg/dL - Calcium (Ca): 8.5 - 10.2 mg/dL - Chloride (Cl): 96 - 106 mmol/L - Creatinine (Cr): 0.6 - 1.2 mg/dL - Sodium (Na): 135 - 145 mmol/L - Potassium (K): 3.5 - 5.1 mmol/L - Glucose (fasting): 70 - 99 mg/dL Liver Function Tests (LFTs) - Albumin: 3.5 - 5.0 g/dL - Alkaline Phosphatase (ALP): 44 - 147 U/L - Alanine Aminotransferase (ALT): 0 - 35 U/L - Aspartate Aminotransferase (AST): 0 - 35 U/L - Total Bilirubin (Tbili): 0.1 - 1.0 mg/dL Renal Function Tests - Creatinine (Cr): 0.6 - 1.2 mg/dL - Urea Nitrogen (BUN): 7 - 20 mg/dL - BUN/Creatinine Ratio: 10:1 - 20:1 - Urine Specific Gravity (USG): 1.010 - 1.030 Cardiac Enzymes - Troponin:
