Interpretive Data

Assay Display Interpretive Data
Acetone Lvl Acetone concentrations greater than or equal to 50 mg/L may indicate toxicity. Acetone concentrations of up to 750 mg/L may be seen in diabetic ketoacidosis. Acetone is also a metabolite of isopropanol. This test was developed and its performance characteristics determined by Dartmouth-Hitchcock Med Ctr. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
Ethanol Lvl-GC Ethanol concentrations of greater than or equal to 800 mg/L meet the legal definition of intoxication while driving in both NH and VT. In some states that legal definition of DUI is >500 mg/L. Some degree of impaired speech and driving performance can be seen at concentrations as low as 200 mg/L. Concentrations greater than 4 000 mg/L can be fatal. This test was developed and its performance characteristics determined by Dartmouth-Hitchcock Med Ctr. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
Isopropanol Lvl Isopropanol concentrations of greater than or equal to 50 mg/L may indicate toxicity. Isopropanol may also be detected a low concentrations during diabetic ketoacidosis due to the spontaneous reduction of acetone to isopropanol. This test was developed and its performance characteristics determined by Dartmouth-Hitchcock Med Ctr. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
Methanol Lvl Methanol concentrations of greater than or equal to 50 mg/L may indicate toxicity. Concentrations greater than 500 mg/L are usually an indication for urgent hemodialysis. This test was developed and its performance characteristics determined by Dartmouth-Hitchcock Med Ctr. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
