Lab ranges
15 entries
Albumin — lab reference
Inflammation, hydration, liver synthesis, renal loss, and nutrition affect result.
Albumin/globulin ratio — lab reference
Calculated; interpret component values.
Alkaline phosphatase (ALP) — lab reference
Age, bone turnover, liver source, pregnancy, and isoenzymes affect interpretation.
ALT — lab reference
The test method matters. Healthy-population upper limits may be lower than many commercial ranges.
Amylase — lab reference
Not pancreas-specific; interpret with lipase and clinical presentation.
AST — lab reference
Muscle, liver, hemolysis, alcohol, exercise, and medication context matter.
Bilirubin, direct — lab reference
Ask your clinician to review direct and indirect fractions together.
Bilirubin, total — lab reference
Fasting, Gilbert syndrome, hemolysis, and liver disease may alter result.
Creatine kinase (CK) — lab reference
Exercise, muscle mass, sex, race, trauma, injections, and statins affect values.
Gamma-glutamyl transferase (GGT) — lab reference
Alcohol, medications, metabolic disease, and cholestasis may elevate.
Globulin — lab reference
Often calculated. Ask your clinician to consider SPEP/IFE for unexplained abnormalities.
LDH — lab reference
Broad tissue marker; hemolysis can cause false elevation.
Lipase — lab reference
Assay-specific; diagnostic thresholds for pancreatitis are separate.
Prealbumin — lab reference
Negative acute-phase reactant; not a stand-alone nutrition marker.
Total protein — lab reference
Ask your clinician to review albumin, globulin, and electrophoresis when indicated.
About these ranges
These are Dr. Purser’s adult reference ranges. Units, symptoms and health history matter when you discuss a result with your clinician.
