SI UNITS (recommended)


* The SI unit is the recommended method of reporting clinical laboratory results

Salicylic Acid, Acetylsalicylic Acid, Aspirin
Units of measurement
mmol/L, mg/L, mg/dL, mg/100mL, mg%, µg/mL

Salicylate measurements are used in the diagnosis and treatment of salicylate overdose and in monitoring salicylate levels to ensure appropriate therapy.

Salicylates are a class of analgesic, antipyretic and anti‑inflammatory drugs that includes aspirin.

Expected values

Therapeutic range: < 30 mg/dL (< 2.2 mmol/L)

Toxic range: > 35 mg/dL (> 2.5 mmol/L)

Persons not on salicylate therapy have no salicylate in their serum. The expected values are expressed in terms of therapeutic range, which serves only as a guide for interpretation along with other clinical signs and symptoms.

Units description
Millimole per liter mmol/L = mM/L = millimol/L
Milligram per liter mg/L = millig/L = milligram/L = mg/liter
Milligram per deciliter mg/dL = millig/dL = milligram/dL
Milligram per 100 milliliters mg/100mL = millig/100mL = milligram/100mL
Milligram percent mg% = millig% = milligram%
Microgram per milliliter µg/mL = mcg/mL = ug/mL= microg/mL = microgram/mL
