Delivery of oxygen by red blood cells to all cells of the body. Dysfunction in this process causes lack of energy, fatigue, weakness, shortness of breath, dizziness, headaches, pounding or “whooshing” in ears, cold hands or feet, fast or irregular heartbeat. chest pain, pale or yellow skin.
Immune System-Related Markers
White Blood Cells (WBC) [total]
Neutrophils (Absolute and %)
Lymphocytes (Absolute and %)
Monocytes (Absolute and %)
Eosinophils (Absolute and %)
Basophils (Absolute and %)
Total WBCs and the 5 different types. Adding %s = 100%. Adding absolute cells = total WBCs. Fight infection, use phagocytosis to defend the body against invasion by foreign organisms. Produce, transport, and distribute antibodies in the immune response. Can indicate bacterial or viral infections. environmental or food allergies, inflammation.
Coagulation-Related Markers
Platelets
Mean Platelet Volume (MPV)
Vital to coagulation of blood to prevent excessive bleeding. Involved in plaque formation.
Fasting glucose level in the blood after an evening and morning of fasting. Represents glucose from the last 24 hours of food and drink intake.
Kidney-Related Markers
Blood Urea Nitrogen (BUN)
Creatinine
Estimated Glomerular Filtration Rate (eGFR)
BUN/Creatinine Ratio
Estimate of kidney filtration. Elevated BUN and creatinine along with low eGFR may indicate kidney dysfunction.
Electrolyte-Related Markers
Sodium (Na)
Potassium (K)
Chloride (Cl)
Carbon Dioxide (CO2)
Estimate of electrolyte levels. May indicate acidity or alkalinity, adrenal dysfunction.
Calcium (Ca)
Calcium in the blood bound to proteins, mainly albumin. Before supplementing with calcium, rule out calcium absorption and utilization dysfunction by assessing magnesium, phosphorous, vitamin A, and others.
Protein-Related Markers
Total Protein
Albumin
Globulin
Albumin/Globulin (A/G) Ratio
Measurement of two major proteins. Albumin + Globulin = Total Protein. May indicate protein digestion and absorption dysfunction, protein malnutrition, liver dysfunction.
Total cholesterol = HDL + LDL + VLDL. May indicate cardiovascular risk, hypothyroidism, oxidative stress, inflammation, liver dysfunction, insulin resistance.
Fatty Acid Molecules
Triglycerides (3 fatty acids attached to a glycerol backbone)
Diets high in carbohydrates and hydrogenated fats are a main cause of elevated triglycerides.

Markers Related to Iron Level in Blood
Iron
Total Iron Binding Capacity (TIBC)
Iron Saturation
Iron must be in its proper form to attach to transferrin to be transported in the blood. Copper is required for that process. Never supplement with iron until copper levels are tested. TIBC is an estimate of transferrin.
