| Hematocrit (Hct) | Female: 36β46% Male: 42β52% | Low values: Anemia; monitor for fatigue, dyspnea, tachycardia, and tachypnea. |
| Hemoglobin (Hgb) | Female: 12β15 g/dl Male: 14β17 g/dl | Low values: Anemia; monitor for fatigue, dyspnea, tachycardia, and tachypnea. |
| Red blood cell (RBC) count | Female: 4β5.5 million/mm3 Male: 4.5β6.2 million/mm3 | Low values: Anemia; monitor for fatigue, dyspnea, tachycardia, and tachypnea. High values: In chronic obstructive pulmonary disease (COPD), this may indicate polycythemia, a compensation for pulmonary dysfunction that makes blood thicker, increases risk of cerebrovascular accident (CVA). |
| Total white blood cell (WBC) count | 5000β10,000/mm3 | >10,000 indicates systemic infection (more than just local colonization). |
| Platelets and thrombocytes | 200,000β500,000/mm3 | 30,000β50,000: Risk of internal hemorrhage. |
| Erythrocyte sedimentation rate (ESR) | Female: 1β25 mm/h Male: 0β17 mm/h | Bad if elevated. Used to diagnose, or follow the course of, inflammatory diseases (e.g., rheumatic conditions). |
| Creatinine | Female: 0.6β1.2 mg/dl Male: 0.5β1.1 mg/dl | Renal function measure: High values are bad. May indicate nephropathy, or end-stage renal disease. |
| Potassium (K) | 3.5β5.0 mEq/l | Results of low K: Ventricular arrhythmias. Results of high K: Ventricular arrhythmias and asystole. |
| Calcium (Ca) | 8.2β10.2 mg/dl | Results of low Ca: Osteoporosis, muscle spasms or tetany, calcium deposits in tissue, cardiac arrhythmia, and asystole. Results of high Ca: thirst, polyuria, renal stones, decreased muscle tone, tachycardia, cardiac arrhythmia, and asystole. |
| Sodium (Na) | 136β145 mEq/l | Results of low Na: postural hypotension, abdominal cramps, headache, fatigue, and weakness. Results of high Na: edema and tachycardia. |
| Fasting blood glucose (FBG) | 70 to 99 mg/dL | 100 to 125 mg/dL: Impaired fasting glucose (pre-diabetes). >126 mg/dL: Diabetes. |
| Serum c-telopeptide collagen | Adult male 18β29 Years 87β1200 pg/mL 30β39 Years 70β780 pg/mL 40β49 Years 60β700 pg/mL 50β68 Years 87β345 pg/mL Adult female 18β29 Years 60β640 pg/mL 30β39 Years 60β650 pg/mL 40β49 Years 40β465 pg/mL | High in osteoporosis, osteopenia, and primary hyperthyroidism. |
| Alkaline phosphates | 30β120 IU/L | High values: liver disease, osteoclastic activity, Paget's disease, bone cancer, and osteoporosis. |
| Prothrombin time (PT) | 1β18 sec | Measures extrinsic clotting of blood. Prolonged in liver disease, impaired vitamin K production, and surgical trauma with blood loss. |
| Partial thromboplastin time (PTT) | By laboratory control | Measures intrinsic clotting of blood and congenital clotting disorders. Prolonged in hemophilia A, B, and C. |
| International Normalized Ratio (INR) | Without anticoagulant therapy: 1 Anticoagulant therapy target range: 2β3 | Measures extrinsic clotting function. Increased with anticoagulant therapy. |
| Bleeding time (BT) | 1β6 min | Measures quality of platelets. Prolonged in thrombocytopenia. |
