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.
