Normal Hgb level
Male -14-17
Female-12-16
Reasons for elevated Hgb
Polycythemia, smoker, COPD, dehydration, prolonged tourniquets, transfusion
Reasons for decreased Hgb
Blood loss, fluid overload (hemodilution), anemia, nutritional deficiency, renal insufficiency, aplastic anemia, phlebotomy
Normal WBC level
5-10
Elevated WBC cause
Infection, inflammation, mania, acute stress, leukemia
Decreased WBC
Immunosuppression, medication induced, radiation, nutritional deficiency
Normal platelets
140-400
Decreased platelets
Bleeding, polycythemia, leukemia, inflammation, malignancy, chronic hypoxia
Elevated platelets cause
Clumping, splenomegaly, aplastic anemia, leukemia, medication induced
Normal neutrophil level
1800-8000
Reasons increase neutrophils
Acute stress, inflammation, tumors, steroids, epinephrine, lithium, bleeding, seizures, myeloproliferative disorder.
