At a Glance
Why Get Tested?
To detect aspirin overdose and guide hospital treatment or to monitor aspirin therapy of inflammatory disease such as rheumatoid arthritis to guard against overdosage
When to Get Tested?
When you have symptoms such as nausea, rapid breathing, ringing in the ears (tinnitus), or confusion that may be from taking too much aspirin or medications with salicylate ingredients; when it is suspected that your child may have ingested a significant quantity of a salicylate; at regular intervals when monitoring an overdose; sometimes on a regular basis if you take a salicylate on prescription for rheumatoid arthritis or another autoimmune disorder
A blood sample taken from a vein usually in an arm
Test Preparation Needed?
None, but your doctor may ask when you last took a salicylate and the amount taken. If you regularly take a prescription salicylate, your doctor may want to collect blood just prior to your next dose (trough level). Tell your doctor about any other medications you are taking.
