Urine based screen tests for multiple drugs of abuse range from simple immunoassay tests to complex analytical procedures. The speed and sensitivity of immunoassays have made them the most widely accepted method to screen urine for multiple drugs of abuse. The One Step Drug Screen Test Card (Urine) is a lateral flow chromatographic immunoassay for the qualitative detection of following drugs without the need of instruments.1
Multi-Drug One Step 5 Urine Drug Screen Test Panel (MET/COC/MOP/AMP/THC)
(1)The One Step Drug Screen Test Panel (Urine) is an immunoassay based on the principle of competitive binding.Drugs which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody.
(2)During testing,a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody coated on the particles. The antibody coated particles will then be captured by the immobilized drug conjugate and a visible colored line will show up in the test line region of the specific drug strip. The colored line will not form in the test line region if the drug level is above its cut-off concentration because it will saturate all the binding sites of the antibody coated on the particles.
2.Storage and Stability
(1)Store as packaged in the sealed pouch either at room temperature or refrigerated (2-30°C). The test panel is stable through the expiration date printed on the sealed pouch. The test panel must remain in the sealed pouch until use. DO NOT FREEZE. Do not use beyond the expiration date.
3.Directions for Use
Allow the test panel,urine specimen,and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
(1)Bring the pouch to room temperature before opening it.Remove the test panel from the sealed pouch and use it as soon as possible.
(2)Take off the cap outside of the test end. With arrows pointing toward the urine specimen,immerse the test panel vertically into the urine specimen for at least 10-15 seconds. Immerse the test panel to at least the level of the wavy lines on the strip(s),do not pass the arrows on the test panel when immersing the panel.See the illustration below.
(3)Place the test panel on a non-absorbent flat surface,start the timer and wait for the colored line(s) to appear.Read results at 5 minutes.Do not interpret results after 10 minutes.
