Q1.What's the method you 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 your packing of the tests?
A: If you choose the low cost, we will suggest you the bulk packing to go. Which means 1 test in a single pouch, then 100/25 pouches in a plastic bag, 50 bags in a carton. If you need to sell in pharmacy/chain shop or some countries which have strict requirements about the packing, you can choose to pack in a box, like 30 pcs in a box, or even 1 test in a single box.

Q4: What's the main differences when comparing products from different suppliers?
A: You 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: You can judge from the 4 facts: 
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. You 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.
