Product Description

 

Intended Use

Cotinine (COT) Rapid Test is an immuno-chromatographic assay for the qualitative determination of the presence of Cotinine (COT) listed in the table below.
 

Drug(Identifier)	Calibrator	Cut-off level
Cotinine (COT)	Cotinine	200 ng/mL

 

This assay provides only a preliminary analytical test result. Gas Chromatography/Mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to Cotinine (COT) of abuse test result, particularly when preliminary positive results are indicated.

 

Introduction

Cotinine is the first-stage metabolite of nicotine, a toxic alkaloid that produces stimulation of the autonomic ganglia and central nervous system when in humans. Nicotine is a drug to which virtually every member of a tobacco-smoking society is exposed whether through direct contact or second-hand inhalation. In addition to tobacco, nicotine is also commercially available as the active ingredient in smoking replacement therapies such as nicotine gum, transdermal patches and nasal sprays. In a 24-hour urine, approximately 5% of a nicotine dose is excreted as unchanged drug with 10% as cotinine and 35% as hydroxycotinine; the concentrations of other metabolites are believed to account for less than 5%. While cotinine is thought to be an inactive metabolite, it's elimination profile is more stable than that of nicotine which is largely urine pH dependent. As a result, cotinine is considered a good biological marker for determining nicotine use.

Contents

• Drug Test.
• Desiccant
• Leaflet with instruction for use.

Storage & Statibility

• The kit should be stored at 2-30°C until the expiry date printed on the sealed pouch.
• The test must remain in the sealed pouch until use.
• Keep away from direct sunlight, moisture and heat.
• Do not freeze .
• Care should be taken to protect the components of the kit from contamination. Do not use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipment, containers or reagents can lead to false results.

Operation

 

Test must be in room temperature (15ºC to 30ºC)

1. Donor collects urine specimen in a urine cup.

2. Cassette and Strip Operation:

2.1 Cassette:

Remove test device/cassette from the sealed pouch.

Lay the cassette flat, add 2-3 drops of urine specimen by sample dropper into the sample well.

2.2 Strip:

Remove test strip from the sealed pouch.

Dip the arrowed end of the test strip into the container with urine sample, take it out in 5seconds and lay flat.

3. The result should be read at 5 minutes. Do not interpret the result after 10 minutes. See the illustration

below:

 

 

Interpretation of Results

Preliminary positive (+)

Only one colored band appears, in the control region (C). No colored band appears in the test region (T).

Negative (-)

Two colored bands appear on the membrane. One band appears in the control region (C) and another band appears in the test region (T).

Invalid

Control band fails to appear. Results from any test which has not produced a control band at the specified read time must be discarded. Please review the procedure and repeat with a new test. If the problem persists, discontinue using the

kit immediately and contact your local distributor.
