UNK fentanyl test strips use a technology known as lateral flow immunoassay,
which is standard method for detecting various substances in biological samples.
This technology is based on the principle of binding between an antigen and an antibody.
UNK fentanyl test strips consist of several components: a sample pad, a conjugate pad, nitrocellulose membrane, and an absorbent pad.
The sample pad is where the biological sample, typically urine or saliva, is applied.
The conjugate pad contains antibodies that are specific to fentanyl. When the sample is applied to the conjugate pad, the antibodies bind to any fentanyl present in the sample.
The next step is the migration of the sample through the nitrocellulose membrane. This membrane contains a test line and a control line. The test line contains immobilized antibodies that are specific to fentanyl. If fentanyl is present in the sample, it will bind to the antibodies on the test line, causing a visible line to appear.
The control line contains immobilized antibodies that are not specific to fentanyl.
This line serves as a control to ensure that the test is working properly.
If the control line does not appear, the test is invalid and should be repeated.
Finally, the sample reaches the absorbent pad,
which collects any excess liquid and completes the test.
Overall, lateral flow immunoassay technology is a simple and effective way to detect the presence of fentanyl in biological samples. UNK fentanyl test strips provide a quick and reliable way for individuals to test their drugs for fentanyl, potentially saving lives and preventing overdoses.
