Tramadol EIA Kit, large test kit

The LZI Tramadol Calibrators are a human urine-based liquid and ready-to-use. The LZI Universal 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 tramadol into the negative calibrator.

*Actual concentrations of these calibrators are confirmed 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).
