What Does a 12 Panel Drug Test Detects?

Standard 12 panel drug test cups typically detect the following 12 substances:

Some 12-panel cups also test additional analytes like adulterants or alcohol metabolites, depending on the version.

How Does a 12 Panel Drug Test Work?

1. Sample Collection

   • Typically, a urine sample is collected in a specialized cup.

   • Many cups feature a tamper-evident screw-top lid and a built-in temperature strip to help validate the sample.

2. Detection Mechanism

   • The inside of the cup has immunoassay test strips that react when specific metabolites are present.

   • After a few minutes (usually around 5), the test lines develop, showing results.

3. Reading the Results

   • Most cups use a control (C) line and test (T) lines:

     • Two lines = Negative

     • One line (only C) = Positive or possible tampering

   • Always follow the manufacturer’s time window for reading. Results read too early or too late may be invalid.

4. Confirmation

   • For legal, clinical, or high-stakes testing, positive results should ideally be confirmed with lab-based testing (e.g., GC-MS) for added accuracy.

Typical Detection Windows

Note: Detection times vary widely based on individual metabolism, hydration, usage history, and other factors.
