16-Panel Surface Swab Drug Test for Powders and Residues

16-Panel Surface Swab Drug Test is designed to identify suspicious substances quickly and reliably. This surface swab drug test allows screening of powders, crushed tablets, drinks and surface residues when there is a need to clarify whether a material may contain narcotic substances.

Unlike urine-based drug tests, this surface swab drug test analyzes the substance itself rather than metabolites in the body. It is intended for identifying drug residues in materials, surfaces and liquids — not for testing personal drug use.

What can be tested?

The surface swab drug test is suitable for:

• Powders: Identify substances present in suspicious loose materials.
• Pills and tablets: Crushed tablets can be dissolved and screened.
• Drinks: Suspected beverages can be diluted and tested.
• Surface residues: Drug traces on tables, floors or other surfaces can be collected using the swab method.
• Plant material: Tobacco or plant fibers can be analyzed as solid samples.

The test provides a clear indication within approximately 5 minutes, making it suitable for situations where rapid clarification is important.

How the surface swab method works

For surface testing, the test strips are swabbed across the suspected area and then placed in clean water. For powders or crushed tablets, a small amount is mixed with water before inserting the test strips. Liquid samples such as drinks are diluted prior to testing. Results are read after approximately 5 minutes.

The surface swab drug test is designed for ease of use and does not require laboratory equipment.

Result interpretation

• Two lines (C and T): Negative result
• Control line (C) only: Positive screening result
• No control line: Invalid test – repeat with a new device

This is a screening test. Positive results can be confirmed by laboratory analysis if required.
