Limitations

If acute acetaminophen toxicity is suspected, correlation of levels with hours after ingestion is required for interpretation (using the Rumack-Matthew nomogram). In general, a value of 200 ug/ml within 4 hours of ingestion or >50 ug/ml at 12 hours predicts severe liver damage, and treatment with acetylcysteine is suggested.

Reference Range

Negative
Abnormal: Small, Moderate, Large

Clinical Significance

The presence of acetone may indicate exposure to acetone; it is also a metabolite of isopropanol and may be detected during ketoacidosis.
