Methadone Metabolite Level 1 Control (75 ng/mL)

Methadone Metabolite (EDDP) (100) Calibrators are for use as calibrators in the qualitative and semi-quantitative calibration of the Methadone Metabolite (EDDP) Enzyme Immunoassay at the cutoff value of 100 ng/mL on automated.

The LZI Methadone Metabolite (EDDP) (100) Calibrators are human urine-based liquids, and ready to use. The LZI Negative Calibrator is a processed drug-free human urine matrix containing buffers, stabilizers, and less than 0.1 % of sodium azide. The calibrators are prepared by spiking known concentrations of 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) into the LZI Negative Calibrator. Calibrators are made from NIST traceable standards.  *Actual concentrations of these calibrators are within ±10 % of the target value as determined by GC/MS or LC/MS. Values are provided only as guidelines and laboratories should determine the ranges based on their own test system and tolerance (2). 

Storage Temp: 2-8°C

Precautions and Warning 

• • The LZI Methadone Metabolite (EDDP) (100) Calibrators are for in vitro diagnostic use only. Harmful if swallowed.

• • The calibrators contain sodium azide, which may react with lead or copper plumbing to form potentially explosive metal azide.  When disposing such liquids always flush with a large volume of water to prevent azide build-up (3).

• • The calibrators are prepared from non-sterile human urine. They are not tested by licensed reagents for the presence of antibodies to human immunodeficiency viruses, the hepatitis antigens, and/or anti- hepatitis antibodies. They should be handled as potentially infectious. Always use good laboratory practice to avoid any skin contact or ingestion.

• • Do not use the calibrators beyond their expiration dates.
