Interpretive Data

Assay Display Interpretive Data
U Amphetamines Screen The amphetamine screen detects d-amphetamine and d-methamphetamine at concentrations >300 ng/mL. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes.
U Barbiturates Screen The barbiturate screen detects barbiturates at concentrations >200 ng/mL. Note: Not all barbiturates cross-react equally with antibody used in this screen. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes.
U Benzodiazepines Screen The benzodiazepines screen detects benzodiazepines at concentrations >100 ng/mL. Not all benzodiazepines cross-react equally with antibody used in this screen. Due to the low dosage of clonazepam false negatives may be obtained due to low concentration of clonazepam metabolites. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes.
U Cannabinoid Screen The marijuana metabolites screen detects the THC metabolite (11-nor-9-carboxy-delta 9-THC) at concentrations >20 ng/mL. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes.
U Cocaine Screen The cocaine metabolites screen detects benzoylecgonine (Cocaine Metabolite) at concentrations >150 ng/mL. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes.
U Ethanol Screen This urine ethanol assay detects ethanol at concentrations >/= 100 mg/L.
U TCA Screen The tricyclics screen detects tricyclic antidepressants at concentrations ≥150 ng/mL. Not all tricyclics cross-react equally with the antibody used in this screen. A “Presumptive Positive” result indicates that the screening result was positive but has not yet been confirmed by a highly-specific method. As with any screen occasional false positive results from cross-reacting substances may occur. Not for Medico-Legal Purposes. This test has not been cleared by the US FDA. Performance characteristics of this test were determined by Dartmouth-Hitchcock Medical Center in accordance with CLIA requirements. This laboratory is qualified under CLIA to perform high-complexity testing.
