Complete Blood Count (CBC)
A CBC measures cells circulating in blood, including red cells, white cells, and platelets.
Comprehensive Metabolic Panel (CMP)
A CMP groups markers related to electrolytes, kidney function, liver enzymes, and glucose.
Lipid Panel
Lipid panels report cholesterol fractions and triglycerides from a blood sample.
Hemoglobin A1c
A1c reflects average blood glucose over roughly the prior two to three months.
Glucose
Blood glucose measures the amount of sugar circulating at the time of the draw.
Kidney Markers
Kidney-related labs often include creatinine and estimated GFR (eGFR).
Liver Enzymes
ALT and AST are enzymes commonly included on metabolic panels.
Thyroid Markers
TSH is a common first-line thyroid marker reported by laboratories.
Iron Stores (Ferritin)
Ferritin is a common marker related to iron storage.
Vitamin D
25-hydroxyvitamin D is the usual laboratory marker for vitamin D status.
Vitamin B12
Vitamin B12 (cobalamin) is measured in blood to assess B12 status.
Testosterone
Total testosterone is a common hormone marker reported from blood draws.
Hemoglobin
Hemoglobin is the oxygen-carrying protein measured as part of a CBC.
Creatinine
Creatinine is a kidney filtration marker commonly included on metabolic panels.
eGFR
Estimated GFR summarizes kidney filtration using laboratory equations.
ALT
ALT is a liver enzyme commonly reported on metabolic panels.
AST
AST is an enzyme associated with liver and other tissues.
TSH
TSH is a common thyroid marker.
Ferritin
Ferritin reflects iron storage and may rise with inflammation.
LDL Cholesterol
LDL cholesterol is a lipid fraction commonly listed on lipid panels.
HDL Cholesterol
HDL cholesterol is a lipid fraction on standard lipid panels.
Triglycerides
Triglycerides are fats measured as part of a lipid panel.
Total Cholesterol
Total cholesterol sums major cholesterol fractions on a lipid panel.
