Complete Blood Count (CBC) : Hemoglobin and Hematocrit (H&H)
Hemoglobin 12-14, crematoria 40-54.
Common Cause for Decreased H&H
Protein malnutrition, acute/chronic blood loss, drug toxicities, anemia, leukemia, renal failure.
Common Cause for Increased H&H
High altitudes, dehydration, late stage emphysema, polycythemia vera.
Complete Blood Count (CBC) : Red Blood Cell Count (RBC)
Common Causes for Decreased RBC
Leukemia, excessive intravascular fluid, chronic renal failure, chemotherapy, radiation, and anemia.
Common Causes for Increased RBC
polycythemia vera, dehydration high altitude, cardiovascular diseases.
MCV = size, MCH = weight of hemoglobin, MCHC indicates the hemoglobin concentration per unit volume of RBC. These values used to differentiate various anemias.
Immature red blood cells
Complete Blood Count (CBC) : Platelets
150,000-400,000. Critical values <50,000 or >1,000,000. Provides info about clotting.
Complete Blood Count (CBC) : White Blood Cell (WBC) Count
4,500-10,000. Body's defense system that responds immediately to foreign invaders.
Common Causes of Decreased WBC Count
Certain anemias, viral infections, drug influences.
Common Causes of Increased WBC Count (Leukocytosis)
acute inflammation/infection, tissue necrosis, leukemia, collagen diseases.
Complete Blood Count (CBC) : White Blood Cell (WBC) Differential
Identifies numbers of specific WBC's, neutrophils, eosinophils, basophils.
White Blood Cell (WBC) Differential : Neutropils
First line of defense against acute infections (Segments are mature and Bands are immature.)
White Blood Cell (WBC) Differential : Eosinophils
Increase during allergic or parasitic conditions, increased steroid levels produced by medication or stress can cause decrease.
White Blood Cell (WBC) Differential : Basophils
Increase during healing.
White Blood Cell (WBC) Differential : Monocytes
Second line of defense against bacterial infections/foreign substances - respond late during acute phase of infection or inflammation.
White Blood Cell (WBC) Differential : Lymphocytes
Occur in chronic and viral infections - often seen in chronic lymphoctyic leukemia. May be decreased during excessive adrenocortical hormone secretion or steroid therapy.
Basic Metabolic Profile (BMP) (Chemistry 7) : Glucose Level
Basic Metabolic Profile (BMP) (Chemistry 7) : BUN and Creatinine
BUN 5-25, creatinine 0.5-1.5. Most often elevated with dehydration or renal damage/disorder. Creatine more sensitive to kidney disease.
Basic Metabolic Profile (BMP) (Chemistry 7) : Glomerular Filtration Rate (GFR)
40-60 decreased renal reserve; 20-40 renal insufficiency; 10-20 renal failure; <10 end stage renal disease (ESRD.) 75% loss results in elevated sodium and water retention.
Basic Metabolic Profile (BMP) (Chemistry 7) : Elecrtolytes
Sodium 135-145; potassium 3.5-5, elevated causes irritability, metabolic acidosis, cardiac arrhythmias; chloride 95-105.
Platelets, prothrombin time (PT), international normed ratio (INR), partial thromboplastin time (PTT.) Look for elevations in patients on anticoaglants, liver disease.
Liver Function Studies : Total Bilirubin
0.1-1.0. Elevations in autoimmune or hemolytic induced reactions, liver damage, CHF. May cause jaundice.
Liver Function Studies : AST/SGOT
8-38. Enzyme normally found in heart/liver muscles. Increase with acute MI, liver damage.
Liver Function Studies : ALT/SGPT
10-35. Enzyme primarily in liver cells; used to diagnose liver disorders. Differentiates jaundice caused by liver disease and hemolytic disorders.
Liver Function Studies : Alkaline Phosphatase
Nonspecific indicator of liver or bone disease.
Pancreatic Studies : Amylase
60-160. Enzyme changes starch to sugar. Rises with damage to pancreas. Causes severe inflammation and pain. Also with surgery involving gallbladder and stomach
Pancreatic Studies : Lipase
20-80. Enzyme secreted by pancreas aids in digesting fats. Increase in blood when damage to pancreas.
18-24.5 healthy BMI. Labs are pre-albumin, albumin, transferrin, liver legels may be low with inflammatory metabolic response.
