2C-B
A 2C-B urine test is a qualitative screening that detects the presence of 2C-B (4-bromo-2,5-dimethoxyphenethylamine) or its metabolites in urine. 2C-B is a synthetic psychedelic phenethylamine with stimulant and hallucinogenic properties.
What It Measures
This test detects the presence of 2C-B and its metabolites in urine. 2C-B is a synthetic phenethylamine compound that is not detected by standard drug screening panels. The test provides a qualitative result indicating whether 2C-B metabolites are present above the assay cut-off level.
Because 2C-B is structurally distinct from other commonly screened substances, a targeted assay is required for reliable detection.
Because 2C-B is structurally distinct from other commonly screened substances, a targeted assay is required for reliable detection.
Why It Matters
Detection of 2C-B may be relevant for clinical assessment, forensic investigations, and extended drug screening programmes. The substance is not included in standard workplace drug panels, making targeted testing important when its use is suspected.
Accurate identification supports appropriate clinical decision-making and helps distinguish 2C-B from other phenethylamine derivatives.

When to Test
Testing may be relevant when 2C-B use is suspected, as part of extended drug screening panels, or during forensic evaluations. Standard immunoassay panels do not detect 2C-B.

Frequently Asked Questions
How long can 2C-B be detected in urine?
2C-B may be detectable in urine for approximately 1 to 3 days after use. The detection window can vary depending on dosage, individual metabolism, and hydration levels. Consult a healthcare professional for more details.
Is 2C-B detected on standard drug screening panels?
No, 2C-B is not included in standard workplace drug screening panels such as the 5-panel or 10-panel tests. A specific, targeted assay using techniques such as mass spectrometry is required for detection.
What should I expect from a 2C-B urine test?
The test involves providing a urine sample, which is analysed for the presence of 2C-B metabolites. Results are qualitative, indicating whether the substance is detected above the assay threshold. Confirmatory testing may be performed if the initial screening is positive.
