One step drug Cotinine / COT urine test

Product Description
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.  The plasma half-life of nicotine is approximately 60 minutes following inhalation or parenteral administration. Nicotine and cotinine are rapidly eliminated by the kidney; the window of detection for cotinine in urine at a cutoff level of 200 ng/mL is expected to be up to 2-3 days after nicotine use.

 SPECIMEN COLLECTION AND STORAGEThe COT Rapid Test Device (Urine) is intended for use with human urine specimens only.Urine collected at any time of the day may be used.Urine specimens must be collected in clean, dry containers.Turbid specimens should be centrifuged, filtered, or allowed to settle and only the clear supernatant should be used for testing.Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Urine specimens may be stored at 2-8°C for up to 2 days. For long term storage, specimens should be kept below -20°C.Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents. PROCEDUREBring tests, specimens, and/or controls to room temperature (15-30°C) before use.

Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. For best results, the assay should be performed within one hour.Using the provided disposable pipette, transfer 3 drops of specimen (approximately 120 µL) to the specimen well (S) of the device and start the timer.

Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the membrane.

Wait for the colored band(s) to appear. The result should be read at 5 minutes. Do not interpret the result after 8 minutes

INTERPRETATION OF RESULTS
POSITIVE: Only one colored band appears, in the control region (C). No apparent colored band appears in the test region 
NEGATIVE: Two colored bands appear on the membrane. One band appears in the control region (C) and another band appears in the test region 
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.

NOTE:

The intensity of color in the test region (T) may vary depending on the concentration of analytes present in the specimen. Therefore, any shade of color in the test region should be considered negative. Note that this is a qualitative test only, and cannot determine the concentration of analytes in the specimen.Insufficient specimen volume, incorrect operating procedure or expired tests are the most likely reasons for control band failure.

INTERPRETATION OF RESULTS
Negative: Two pink-colored bands appear, one in the control region and one in the test region. A negative result indicates free drug is absent from urine or at concentrations lower than the detection cut-off level of the test.
Positive: One pink-colored band appears in the control region with no apparent band appering in the test region. A positive result indicates free
drug is present in urine at concentrations at or exceeding the detection cut-off  level of the test.
Invalid: No band appears in the control region, or a pink-colored band appears in the test region only. An invalid test result may be due to improper assay procedures or damage to the device. If results are invalid, the assay is inconclusive and the specimen should be re-tested using a new test device.
Note: The band intensity may be weaker or stronger than that of the control band.

FAQ
Q1: What's the method u use to do the test?
A: Colloidal Gold Method.


Q2: What's ur MOQ ?
A: Always, for strip format, the MOQ is 5000pcs. While for cassette format, MOQ is 2000pcs, same as midstream.


Q3: What's ur packing of the tests?
A: If u choose the low cost, we will suggest u the bulk packing to go. Which means 1 test in a single pouch, then 100/40 pouches in a plastic bag, 50 bags in a carton. If u need to sell in pharmacy/chain shop or some countries which have strict requirements about the packing, u can choose to pack in a box, like 100pcs in a box, or even 1 test in a single box.


Q4: What's the main differences when comparing products from different suppliers?
A: U can compare the mainly features of the test: Accuracy, Sensitivity, Specificity, and then the Price.
 
Q5: Some tests can be tested with serum/plasma or with whole blood, so what's the difference?
A: Well, if the specimen is whole blood, people will need buffer, lancet and alcohol swab to help the test. If they buy all the accessories, they can test very easily at home. But if the specimen is serum/plasma, it will need centrifuge to separate serum from whole blood first. This way, it's better to use at lab or hospital. And in some words, serum/plasma test will always give a more accurate results.


Q6: How can i distinguish a good test kit?
A: U can judge from the 4facts:Technical data: Such as the accuracy, specificity and sensitivity.
Pouch sealing: Tight enough. If the foil pouch is not sealed well, the humidity in circustance will destroy the reactivity of antibodies labeled on NC membrane. Shelf life will be shorten down.

Flow speed: The shorter the better?? NO!! The reaction of antibodies on NC membrane and antigens in specimen usually requires quite a while to work sufficiently. U can refer to the instruction for more accurate time.

Background: Good test usually gives clean background after running. If there are red smears in the reading window, it usually caused by bad colloidal gold technology or bad NC membrane. Sometimes, the defect caused false positive result in practice
