Human chorionic gonadotropin (HCG) is a hormone, produced by the developing placenta shortly after the conception and secreted into the urine. One Step hCG Pregnancy Urine Test is a rapid pregnancy test. It adopts double antibody sandwich method detects the presence of human chorionic gonadotropin (hCG), which appears in urine very early during pregnancy.
1. Open the pouch and remove the test device.
2. Place the test device on a clean and level surface. Hold the dropper vertically and transfer 3 full drops of urine to the specimen well of the test device,and then start the timer. Avoid trapping air bubbles in the specimen well.
3. Wait for the color line(s) to appear. Depending on the concentration of HCG,positive results may be observed in as little as 40 second. For all results,wait 5 minutes to confirm the observation. Do not interpret the result after 10 minutes.
Positive: Two distinct red lines appear. One line shuld appear in each control (C) and test (T) regions.
Negative: One red line appears in the control region (C). No red or pink line appears in the test region (T)..
Invalid: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device. If the problem persists,discontinue using the test kit immediately and contact your local distributor.
Note: The intensity of the red color in the test line region (T) will vary depending on the concentration of HCG present in the specimen. However, neither the quantitative value nor the rate of increase in HCG can be determined by this qualiative test.
Easy to use Easy to read High accuracy High speed
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
