Description These test kits are a rapid chromatographic immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody. Keep test strips in sealed pouches until ready for use. Directions for use: Remove test kit from sealed pouch. Immerse test kit in urine specimen for at least 10-15 seconds. Do not pass the maximum line on the test strip when immersing. Place the test strip on a non-absorbent flat surface for 5 minutes. Two lines = negative test result. One line = positive test result.
