One Step Caffeine Test is a rapid one step test for the qualitative detection of Caffeine and its principal metabolites in human urine at specified cut-off level.
For in vitro diagnostic use only. For professional use only.
INTENDED USE
The One Step Caffeine Test is a lateral flow chromatographic immunoassay for the detection of Caffeine in human urine at the cut-off concentration of 1000ng/ml. This assay provides only a qualitative, preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
PERFORMANCE CHARACTERISTICS
A. Sensitivity
One Step Caffeine Test has set the screen cut-off for positive specimens at 1000 ng/mL for Caffeine as a calibrator. The test device has been proved to detect above 1000 ng/mL of Caffeine in urine at 5 minutes.
B. Specificity and cross reactivity
To test the specificity of the test, the test device was used to test Caffeine, drug metabolites and other components of the same class that are likely to be present in urine, All the components were added to drug-free normal human urine. These concentrations below also represent the limits of detection for the specified drugs or metabolites.
Component Concentration (ng/ml)
Caffeine 1000
C. Interfering substances
Considering the complexity of clinical urine specimens and the possibility that various urine specimens contain potentially interfering substances, for example Acetoacetic Aci, Acetone, Albumin etc., we simulated above situations by adding the potentially interfering substances to a certain concentration as specimen. The following components show no cross-reactivity when tested with One Step Caffeine Test at a concentration of 100 mg/ml.
SUMMARY
Caffeine is a kind of plant alkaloids, that can be found in many plants. It is a central nervous system stimulant, being able to drive away the drowsiness and restore energy for a moment, clinically for the treatment of neurasthenia and coma recovery. The coffee, tea, soft drinks and energy drinks with caffeine are very popular. Therefore, caffeine is the most widely used for psychotropic drugs in the world.
