Detection of xylazine

If your tap water is “hard” it contains a lot of calcium and magnesium ions, which can interfere with lateral-flow strip chemistry. You may get better results by using DI (deionized) water.
Detected (no test line) Inconclusive (faint test line, 1–3 out of 10) Missed (clear test line, 4–10 out of 10)
