Complete Blood Count (CBC)
WBC: White Blood Cell Count
- Normal Range: 4,500-11,000 cells/mcL
- What it Means: WBCs fight infection, so an elevated count may indicate an infection or inflammation.
RBC: Red Blood Cell Count
- Normal Range: 4.5-5.9 million cells/mcL (men), 4.1-5.1 million cells/mcL (women)
- What it Means: RBCs carry oxygen throughout the body. A low count may indicate anemia, while a high count may suggest dehydration or a blood disorder.
HGB: Hemoglobin
- Normal Range: 12-16 g/dL (men), 11-15 g/dL (women)
- What it Means: Hemoglobin carries oxygen within RBCs. Low levels may indicate anemia, while high levels may suggest dehydration or a blood disorder.
HCT: Hematocrit
- Normal Range: 40-54% (men), 36-48% (women)
- What it Means: Hematocrit measures the percentage of RBCs in your blood. A low hematocrit may indicate anemia, while a high hematocrit may suggest dehydration or a blood disorder.
MCV: Mean Corpuscular Volume
- Normal Range: 80-96 fL
- What it Means: MCV measures the average size of RBCs. A low MCV may indicate iron deficiency anemia, while a high MCV may suggest vitamin B12 or folate deficiency.
MCH: Mean Corpuscular Hemoglobin
- Normal Range: 27-31 pg
- What it Means: MCH measures the average amount of hemoglobin in each RBC. A low MCH may indicate iron deficiency anemia, while a high MCH may suggest a blood disorder.
MCHC: Mean Corpuscular Hemoglobin Concentration
- Normal Range: 32-36 g/dL
- What it Means: MCHC measures the concentration of hemoglobin in each RBC. A low MCHC may indicate anemia, while a high MCHC may suggest a blood disorder.
Comprehensive Metabolic Panel (CMP)
BUN: Blood Urea Nitrogen
- Normal Range: 7-20 mg/dL
- What it Means: BUN measures the amount of nitrogen in your blood, which is a waste product of protein metabolism. Elevated BUN levels may indicate kidney problems or dehydration.
CRE: Creatinine
- Normal Range: 0.6-1.2 mg/dL (men), 0.5-1.1 mg/dL (women)
- What it Means: Creatinine is a waste product of muscle metabolism. Elevated creatinine levels may indicate kidney problems.
GLU: Glucose
- Normal Range: 70-99 mg/dL
- What it Means: Glucose is a type of sugar that serves as the body's main source of energy. Elevated glucose levels may indicate diabetes or impaired glucose tolerance, while low glucose levels may suggest hypoglycemia.
AST: Aspartate Aminotransferase
- Normal Range: 10-40 U/L
- What it Means: AST is an enzyme found in the liver, heart, and skeletal muscle. Elevated AST levels may indicate liver damage or heart attack.
ALT: Alanine Aminotransferase
- Normal Range: 7-56 U/L
- What it Means: ALT is an enzyme found in the liver. Elevated ALT levels may indicate liver damage.
ALP: Alkaline Phosphatase
- Normal Range: 30-120 U/L
- What it Means: ALP is an enzyme found in the liver, bones, and kidneys. Elevated ALP levels may indicate liver or bone problems.
Lipid Panel
TC: Total Cholesterol
- Normal Range: Less than 200 mg/dL
- What it Means: Total cholesterol includes LDL (bad) and HDL (good) cholesterol. High levels of total cholesterol may increase your risk of heart disease.
LDL: Low-Density Lipoprotein (Bad Cholesterol)
- Normal Range: Less than 100 mg/dL
- What it Means: LDL cholesterol can build up in your arteries, increasing your risk of heart disease and stroke.
HDL: High-Density Lipoprotein (Good Cholesterol)
- Normal Range: 40 mg/dL or higher (men), 50 mg/dL or higher (women)
- What it Means: HDL cholesterol helps remove LDL cholesterol from your arteries, reducing your risk of heart disease.
Thyroid Panel
TSH: Thyroid-Stimulating Hormone
- Normal Range: 0.4-4.0 mIU/L
- What it Means: TSH stimulates the thyroid gland to produce thyroid hormones. Elevated TSH levels may indicate an underactive thyroid, while low TSH levels may suggest an overactive thyroid.

Vitamin D Test
25(OH)D: 25-Hydroxyvitamin D
- Normal Range: 30-100 ng/mL
- What it Means: 25(OH)D is a form of vitamin D that is produced in the skin when exposed to sunlight. Low levels of vitamin D may increase your risk of osteoporosis and other health problems.
