Drug testing products

Drug testing products are tools or reagents that are used to detect the ingestion of drugs into the human body.
Common types:
Urine test kits: Determine whether drugs are used by detecting the presence of drug metabolites in urine.
Saliva test kits: Utilizes drug-related substances in saliva for detection.
Hair test: analyzes drug residues in hair to detect drug use over a longer period of time.
Detection Principle:
Immunoassay: based on the specific binding of antigen to antibody.
Chromatography: e.g. gas chromatography, liquid chromatography, etc., used to separate and identify drug components.
Characteristics and uses:
Rapid and convenient: able to provide test results in a relatively short period of time.
Aiding law enforcement: widely used in anti-drug work and judicial procedures.
Health monitoring: helps individuals or organizations to know whether there is drug abuse behavior.

Different types of drug testing products have different compositions. The following is a description of the composition of common drug testing products:
Drug test strips
Test strips: usually the core component, made of materials such as cellulose membrane, which contains the detection line, quality control line and related antibodies, antigens and other substances. For example, morphine test strips, in the detection zone is encapsulated with morphine – BSA carrier conjugate, the other end of the fixation of morphine monoclonal antibody colloidal gold paper.
Plastic housing or backing: Used to fix and support the test strip to keep it flat and stable for easy handling and observation of results.
Absorbent pad: generally located at one end of the test strip, used to absorb the sample solution, so that the sample can be uniformly diffused and reacted on the test paper.
Sample addition area: is the location of the sample drop, usually designed as a round or square area, some will also be equipped with a small funnel-like structure, easy to accurately add the sample, such as urine, saliva, etc. .
Drug Testing Kits
Detection reagent: It is the key part of the kit, which may contain biologically active substances such as antibody, antigen, enzyme, fluorescein, etc., as well as auxiliary reagents such as buffer, substrate, etc., according to the different detection principles. For example, the morphine detection kit using immunocompetitive method contains protein-labeled morphine, morphine monoclonal antibody and so on.
Test strips or test cards: similar to the test strips in the above drug test strips, but may vary in size, shape or performance to suit the overall design of the kit and the testing requirements. Some kits will also come with multiple test cards of different types for testing multiple drugs at the same time.
Sample Collection Container: Used to collect samples from the test subjects, common ones include urine cups, saliva collection tubes, etc. For urine sample collection containers, they are generally required to be clean, sterile and free of residual impurities to avoid interference with the test results.
Instruction manual: It describes in detail how to use the kit, the principle of the test, precautions, results judgment, etc. Users need to follow the instruction manual for operation and results interpretation.
Other accessories: may also include dropper, desiccant, quality control products. The dropper is used to accurately aspirate and transfer the sample; the desiccant is used to keep the environment inside the kit dry and prevent the reagents from moisture deterioration; and the quality control is used to verify the validity of the kit and the accuracy of the testing process.
