Doctors are required to study about labs, what procedures are taken at Out-Patient, Hospitals and other Facilities where blood is drawn relative to their patients’ complaints.

Below I have included a table of labs which patients might have to check for various illnesses, viruses. This is shown as an example.

Blood Components



Hematology Tests:
White Blood Cells (WBC) Fight Infection ↑Infection, acute stress
Red Blood Cells (RBC) Carry Oxygen and waste products ↑Excess red blood cells production, ↓anemia
Hemoglobin (Hgb) Carries Oxygen and removes carbon dioxide from body ↑Excess red blood cell production, ↓anemia
Hematocrit (Hct) %RBC in the blood ↑Excess red blood cell production, ↓anemia
MVC Measures size of RBC Useful in classifying anemias
MCH Measures amount of hemoglobin Useful in classifying anemias
RDW Mathematical calculation measuring the width of RBC’s
Platelet Count Involved in clotting
Differential (% and Absolute Granulocytes, Lymphocytes, Monocytes, Eosinophils, and Basophils) Different types of WBC’s Abnormal counts may mean viral infections, bacterial infections, or allergies
Erythrocyte Sedimentation Rate (ESR) Speed of settling of red blood cells ↑Inflammatory, infectious, and neoplastic diseases
Fast from 10-12 hours

May drink small amount of water (annually)

Important in assessing risk for coronary heart disease and stroke
Cholesterol Diet is major source
HDL “good cholesterol” Predictor of Cardiovascular risk; Helps prevent a buildup of cholesterol on artery walls. ↑ HDL Cholesterol = ↓risk of heart disease
Triglycerides Main storage form of lipids ↑Risk of plaque on arteries
Calculated LDL “bad cholesterol” Cholesterol deposits on artery walls ↑Risk of heart disease recommended <100
Chemistry Tests:
Basic Metabolic Profile (BMP) is a combination of the following tests:

Electrolytes-Sodium(Na), Potassium (K), Chloride(Cl)


Blood Urea Nitrogen (BUN)




Maintain osmotic pressure and fluid balance,

Maintain proper pH,

Regulation of proper function of the heart and other muscles.

Body’s the main source of energy, blood sugar.

Waste produced by the liver and excreted by the kidney.

Waste produced by the liver and excreted by the kidney.

Waste in muscles and blood A blood gas; Important to body’s acid-base balance

The Proper function of nerves, enzymes, muscles and blood clotting.

Sodium: Severe hydration, excessive salt intake, ↓congestive heart failure, kidney disease, vomiting, diarrhea, diuretics.

Potassium: ↑renal disease, uncontrolled diabetes, GI loss, diuretics.

Chloride: ↑dehydration, hyperventilation, renal disease, ↓vomiting, over-hydration, congestive failure.

Glucose:↑diabetes, ↓hypoglycemia

BUN:↑kidney disease

Creatinine:↑kidney disease

CO2: ↑hyperventilation, uncontrolled diabetes, ↓emphysema, prolonged vomiting.

Calcium:↑Hyperparathyroidism, multiple myelomas, bone disease. ↓Hypoparathyroidism, Vitamin D
