Instructions for using the ketamine urine colloidal gold test kit, covering principle, sample collection, procedure, and result interpretation.
This manual describes a rapid, instrument‑free urine test for ketamine metabolites based on a highly specific monoclonal antibody and immunochromatography. The test strip contains a ketamine conjugate and gold‑labeled anti‑ketamine antibody; urine samples migrate by capillary action and produce colored lines indicating the presence of ketamine above the 1000 ng/ml threshold.
The document provides step‑by‑step instructions for sample collection, kit preparation, testing, result reading, quality control, storage conditions, and limitations. It also lists substances that may cause cross‑reactivity and outlines proper disposal and contact information for suppliers. This manual is written in Chinese.
| Detection threshold | 1000 ng/ml |
|---|---|
| Sample storage temperature (short term) | 2‑8 °C for up to 48 h |
| Long‑term sample storage | -20 °C |
| Kit storage temperature | 4‑30 °C |
| Shelf life | 24 months |
The recommended threshold is 1000 ng/ml.
A urine sample can be refrigerated at 2‑8 °C for up to 48 hours.
Only the control line appears; the test line is absent, indicating a concentration above the threshold.
Keep the original packaging at 4‑30 °C, in a cool, dry, light‑protected place; do not freeze.
