TermDefinition
Glucose 70-110
Glucose Diabetes, Stress, Corticosteroids Critical high > 400 critical low < 50
Hemoglobin A1C 2.5 – 5.9% Best control
Hemoglobin A1C Indicates Blood Sugar control or past 2- 3 month period Fair control - 6-8% Poor control - > 8
Blood Urea Nitrogen (BUN) 10-20
Blood Urea Nitrogen (BUN) ↑ in renal or liver disease & dehydration Critical high > 100
Sodium 136-145
Sodium Balances intravascular fluids: ↑ in dehydration; ↓ in hypervolemia Critical high > 160; Critical low < 120
Potassium 3.5 – 5.3
Potassium Narrow range in blood: too high or too low → cardiac dysrhythmias & arrest Critical high > 6.5 Critical low < 2.5
Chloride 98 - 106
Chloride ↑ with excess IV NS; ↓ with NA & K losses
CO2 23 - 30
CO2 Another determinant of metabolic acid base state: ↑ = alkalosis, ↓ = acidosis
Creatinine 0.5 - 1.2
Creatinine Increased in kidney impairment Critical high > 4
Total Bilirubin < 1 Critical value > 12
Total Bilirubin If abn → test direct & indirect ↑ liver diseases → jaundice; ↓ Fe deficient anemia
Calcium 8.8 - 10.8
Calcium Narrow range in blood ; elevated with diuretic use &hyperparathyroidism. ↑ excess demineralization of bone; ↓ → tetany
Total Protein 6.3 – 8.4
Total Protein ↑ in dehydration, V&D; ↓ in malnutrition, liver & kidney disease
Albumin 3.5 - 5
Albumin ↑ in dehydration, V&D; ↓ in malnutrition, liver & kidney disease →3rd spacing & ascites
Cholesterol < 200
Cholesterol ↑ Atherosclerosis, uncontrolled DM, & AMI ↓ Hyperthyroidism, Cushing’s, malabsorption
HDL > 40 men > 50 women
HDL ↑ indicates a decreased cardiac risk
LDL < 100
LDL ↑ indicates an increased cardiac risk
Triglycerides < 150
Triglycerides < 100 low risk of CVD; > 200 high risk of CVD
CPK 30 - 135 55 - 170
CPK Enzyme in heart & skeletal muscle ↑ Muscle damage or disease, AMI, & CVA
LDH 60 – 180 mg/dl
LDH Used to diagnose AMI: ↑ 12 – 24 hrs post MI peaks in 2-5 days and remains ↑ for 6-12 days
Troponin <0.01 ng/mL
Troponin Used to diagnose AMI with rising levels. Decreasing values indicate recent cardiac injury.
BNP < 100 is desired
BNP Used to diagnose CHF; Severe CHF > 400
AST/SGOT 0 - 35
AST/SGOT Specific for liver damage: AST/ALT ratio distinguishes if heart or muscle
ALT/ SGPT 4 - 36
ALT/ SGPT Specific for liver damage; but also heart and muscle damage
ALP 30 - 120 IU/L
ALP Alkaline Phosphatase; high levels in hepatobiliary & bone diseases
Lipase 20-180
Lipase Enzyme secreted by Pancreas: ↑ acute pancreatic disorders ↓ late cancer of pancreas, hepatitis
Amylase 60 - 160
Amylase Enzyme secreted by Pancreas:↑ acute pancreatic disorders ↓ advanced chronic pancreatitis
Ammonia 15 – 45 Hesi
Ammonia Correlates with hepatic failure 10-80 mg/dl Hurst
TSH 0.3 – 3.0
TSH Thyroid stimulating Hormone High TSH is hypothyroid and Low TSH is hyperthyroid.
