Overview

Lab test results usually contain some type of unit of measurement. The units provide a way to report results so that they can be compared. Usually, but not always, the same test is reported in the same units no matter which lab did the test. Units of measurement that may be used for lab test results include:

• Femtolitres.
• Grams (g).
• Grams per decilitre (g/dL).
• Grams per litre (g/L).
• International units per litre (IU/L).
• International units per millilitre (IU/mL).
• Micrograms (mcg).
• Micrograms per decilitre (mcg/dL).
• Micrograms per litre (mcg/L).
• Microkatals per litre (mckat/L).
• Microlitres (mcL).
• Micromoles per litre (mcmol/L).
• Milliequivalents (mEq).
• Milliequivalents per litre (mEq/L).
• Milligrams (mg).

• Milli-international units per litre (mIU/L).
• Millilitres (mL).
• Millimetres (mm).
• Millimetres of mercury (mm Hg).
• Millimoles (mmol).
• Millimoles per litre (mmol/L).
• Milliosmoles per kilogram of water (mOsm/kg water).
• Milliunits per gram (mU/g).
