Diltiazem

Diltiazem

Therapeutic use of diltiazem is typically associated with concentrations between 0.05 to 0.4 mg/L. Toxicity is generally associated with concentrations > 0.8 mg/L.  (Clarke's Analysis of Drugs & Poisons, Third Edition).

Diphenhydramine

Diphenhydramine

High dose therapeutic use of diphenhydramine associated with concentrations of up to 0.3 mg/L. Toxicity associated with concentrations > 1 mg/L.  (Schulz et al. Critical Care 2012, 16:R136).

Direct Anti-Globulin Test (DAT)

Dosulepin (Dothiepin)

Dosulepin (Dothiepin)

High dose therapeutic use of Dosulepin (Dothiepin) associated with concentrations of up to 0.4 mg/L. Toxicity associated with concentrations > 0.8 mg/L.  (Schulz et al. Critical Care 2012, 16:R136)

Drugs of Abuse Screening (DOAS)

Drugs of Abuse Screening (DOAS)

Positive results represent concentrations of drugs above the European Workplace Testing Thresholds with the exception of benzodiazepines.  We have lowered the cut off for this class of drug to 10ug/L to increase the detection of benzodiazepines.

Bromazolam, Etizolam, Flualprazolam, Flubromazolam, THC-COOH glucuronide, Buprenorphine glucuronide and Norbuprenorphine glucuronide will be qualitative only.

Drugs without a cut-off have been assigned one based on chemically similar compounds.

ds DNA Antibody

ds DNA Antibody

Negative = <10 U/mL

Weak positive = 10-15 U/mL

Positive = >15 U/mL

Normal result would be negative.
