The principle of the assay is :LDH converts Lactate to pyruvate, generating NADH from NAD. The NADH interacts with the probe to generate color at 450nm. The amount of colored product formed is directly proportional to the LDH activity in the sample.

The First Check Home Drug Test uses Lateral Flow Chromatographic Immunoassay technology, a process that takes place on each of the test strips on the Test Lid. The process works by exposing the urine sample to special chemical reagents within the test strip in a specific order and at a specific speed.
