chemistry
| Term | Definition |
|---|---|
| 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. |
