Troubleshooting Imprecision
Imprecision on the Cannabinoids assay can be the result of:
• Crimped tubing, especially at the cuvette wash station
• Incomplete cuvette wash
Certain types of plastics adsorb cannabinoids (THC) from
solutions, decreasing the concentration. Observe the following
guidelines to prevent adsorption.
• AEROSET sample cups should be filled with 600 µL of
calibrator, control, or specimen to minimize the
surface-to-volume ratio.
• Do not use disposable polyethylene transfer pipettes to
dispense calibrators, controls, or specimens.
• Do not redispense solutions from a pipette back into a
calibrator, control, or specimen container (includes
redispensing after wetting a pipette tip).
• Immerse the pipette tips below the surface of the liquid
only far enough to aspirate the needed volume; this
minimizes contact of the pipette tip with calibrator,
control, or specimen.
