Need to Know Laboratory Values
Serum Electrolytes
A. Sodium (Na) 136 to 145 mEq/L B. Potassium (K) 3 to 5 mEq/L C. Calcium total (Ca) 9 to 10 mg/dl D. Magnesium (Mg) 1 to 2 mEq/L E. Phosphorous (PO) 3 to 4. mg/dL F. Chloride (Cl) 98 to 106mE/L
Arterial Blood Gases
(ABG’s)
A. pH: 7 to 7. B. PaCo2: 35 to 45 mm Hg C. PaO2: 80 to 100 mm Hg D. HCO3 (bicarbonate): 21 to 28 mEq/L
CBC’s
A. RBCs :male 4 to 6 million/uL female 4 to 5 million/uL
B. Hgb males: 14 to 18 females: 12 to 16 g/dL
C. Hct males: 42% to 52% females 37% to 47%
D. WBCs : 5,000 to 10, 000 mm
E. Erythrocyte sedimentation rate (ESR): less than 20 mm/hr
Blood Lipid Levels
A. Total serum cholesterol : desirable less than 200 mg/dl: risk for cardiac or stroke event with levels greater than 150 mg/dL is the target range for therapy and has been shown to be the cut point to decrease cerebrovascular or
Renal Function
A. Serum creatinine: Males: 0 to 1 mg/dL Females: 0 to 1 mg/dL B. BUN : 10 to 20 mg/dL C. Creatinine clearance test: males 90 to 139 mL/min Females: 80 to 125 mL/min
Urinalysis
A. Specific gravity: 1 to 1. B. Protein: 0/dL C. Glucose: less than 0/day D. Ketones: none E. pH: 4 to 8 F. WBC: Males: 0 to 3 per high power field
arterial incidences. B. LD L(low-density lipids): desirable less than 130mg/dl C. HD L (high-density lipids): males 35 to 65 mg/dL; females 35 to 80 mg/dL D. Triglycerides : desirable less than 150 mg/dL; males 40 to 160 mg/dL; females 35 to 135 mg/dL
This is a calculation of glomerular filtration rate (GFR) and is the best indicator of overall renal function.
Females: 0 to 5 per high power field
Anticoagulant Therapy
Coagulation Time
a. Therapeutic INR : 2 to 3. b. PT : 11 to 12 seconds. Therapeutic range for anticoagulant therapy is 1 to 2 times the normal or control value c. Partial thromboplastin time (aPTT): 30 to 40 seconds. Therapeutic range for anticoagulant therapy is 1 to 2 times the normal or control value. d. INR 1. Normal INR is 0 to 1. 2. The INR is a corrected ratio of a client’s prothrombin time to normal 3. Universal test is not affected by variation in laboratory norms 4. If the client requires
Therapeutic Medication
Monitoring
A. Digoxin levels: 0 to 2. ng/mL B. Lithium level: 0 to 1. mEq/L C. Phenobarbital: 10 to 40 mcg/mL D. Theophylline: 10 to 20 mcg/mL E. Dilantin: 10 to 20 mcg/mL
Blood glucose levels
A. Glucose (fasting): 70 to 105 mg/dL B. Glycosylated hemoglobin (HbA1c): 4% to 6% is within the expected reference range. Greater than 8% indicates poor diabetes mellitus control.
