2 TEST PRINCIPLE
The Druglizer LE5 Drug Testing System is based on a competitive lateral flow immunoassay
technique where drug molecules that may be present in the oral fluid sample compete with
the same drug attached to the nitrocellulose wicking membrane, for limited binding sites on
tagged drug specific antibodies.
The antibodies are tagged with gold colloids to produce a conjugate with a red colour.
During testing, an oral fluid sample is absorbed onto the oral fluid collector pad. Chemicals
react with the saliva to remove sample interferences and a portion of this sample wicks
onto the conjugate pad where drugs in the sample react with tagged antibody specific for
that drug. The sample continues to wick by capillary forces along the nitrocellulose
membrane, onto which is attached the same drug of interest. If no drug is present in the
oral fluid sample the tagged antibody can bind to the drug bound to the nitrocellulose and a
red line is produced.
If drugs are present in the oral fluid sample at concentrations greater than the cut-off
concentration, the tagged antibody sites will be saturated with the drug and will not be able
to bind to the nitrocellulose bound drug, hence no result is produced. As the drug
concentration in the sample increases the colour intensity of the test line decreases. The
test strip is not intended to be viewed visually rather it is intended to be interrogated by a
meter. The instrument uses a sophisticated algorithm the determine the result.
