One Step Rapid Single Use & Disposable Alcoscreen Alcohol Saliva Test Kits

     One Step Alcohol Saliva Test Strip is intended for use as a rapid method to detect the presence of alcohol in saliva for blood alcohol concentration (BAC) greater than 0.02%. It has been published that the concentration of alcohol in saliva is almost equal to that in blood 

Using Purpose 

     Rapid Saliva Alcohol Test Strip is intended for use as a rapid method to detect the presence of alcohol in saliva for blood alcohol concentration (BAC) greater than 0.02%. It has been published that the concentration of alcohol in saliva is almost equal to that in blood.
     The rapid test is intended for the semi-quantization of ethyl alcohol in human saliva. To confirm the concentration of positive specimens, an alternate, non-enzymatic technology such as headspace gas chromatography should be used.

PRINCIPLE

Rapid Saliva Alcohol Test Strip is based on the high specify of alcohol oxidase for ethyl alcohol in the presence of peroxides and enzyme substrate such as tetramethylbenzidine (TMB).

The distinct color on reactive pad could be observed in less than 20 seconds after the tip was contacted with saliva samples with the ethyl alcohol concentration greater than 0.02%. It should be pointed out that other alcohols such as methyl, propane and ally alcohol would develop the similar color on the reactive pad. However, these Alcohols are not normally present in saliva

Description

TEST PROCEDURE

1. Remove a strip from the foil pouch by tearing at the notch and place it on a level surface.
2. Saturate the reactive pad by dipping the reaction pad into the saliva specimen collected in a sputum cup, or by applying saliva directly to the reaction pad. After 10 seconds, shake off the excess saliva.
3. Immediately start timer and at 2 minutes, compare the reactive pad with the provided colored chart below  

Interpretation of test result

Positive(+):
A distinct color developed all over the pad. The positive result indicates that the BAC is 0.02% or higher. The alcohol concentration are related to the colored chart above.
Negative (-):
Almost no color change by comparing with the background. The negative result indicates that the BAC is less than 0.02%.
Invalid:
The test should be considered invalid If only the edge of the reactive pad turned color that might be ascribed to insufficient sampling. The subject should be re-tested

SPECIMEN CLOOECTION AND PREPARATION

1. Nothing should be placed into the mouth of the subject for at least 10 minutes prior to saliva collection.This includes food,drink,tabacco products or other materials.
2. Saliva specimen can be colected in a sputum cup or a clean container,or directly applied to the reaction pad of the test strip.
3. Avoid contact with skin by wearing gloves and proper laboratory attire

Q & A

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:

1. Technical data: Such as the accuracy, specificity and sensitivity.
2. 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.
3. 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.
4. 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
