Who Would Dare to Say That the Colloidal Gold Test Kit is Outdated After COVID-19?

After the large-scale novel coronavirus detection, the colloidal gold test kit products are playing the important role again, and its performance is not inferior to nucleic acid detection and magnetic particle chemiluminescence detection. 

Advantages of Rapid Colloidal Gold Test Method

When colloidal gold immunochromatography firstly emerged in the market, some people predicted that this colloidal gold method would change the market of immunoassays. At the time a lot of people didn't think so. But later plenty of facts proved this prophecy. A new diagnostic kit colloidal gold mode is favored by the market with its extreme simplicity.

At early times, colloidal gold test kits are mainly used for early pregnancy and ovulation testing. At that time, as long as a women is at childbearing age, they will be likely to buy OTC product from pharmacy stores. The key reasons of this colloidal gold test kit getting popular is because of its super practicality and simple operation, only a few drops of urine are required, and the results are easy to understand, which can be seen as a classic of home diagnostic products. Early pregnancy detection can be said to be an outstanding representative of colloidal gold method, which fully reflects the rapid advantage of colloidal gold test. As for the subsequent infectious disease testing, drug screening, and myocardial infarction testing, including the most eye-catching new coronavirus testing recently, they all reflect the distinctive features of the colloidal gold test, that is, simple operation, rapid results, and suitable for on-site testing.

All colloidal gold methods are based on the combination of chromatography and immunoreaction to present a quick and intuitive result. The result is easily read by observing the signal band with eyes. Although it is only a semi-quantitative detection mode, the judgment of certain indicators is very timely.

Is Colloidal Gold Test Products Outdated?

With the increasely high demand in detection requirements, people can no longer be satisfied with this single qualitative detection, and have raised many otehr continuous requirements for detection sensitivity and accuracy. As a result, various quantitative tests have emerged, such as fluorescence, luminescence, and magnetic particles. Fluorescent labeling greatly improves the sensitivity of the traditional colloidal gold test, and can even be comparable to radioimmunoassay. By Equiping it with a small and portable reading instrument, seting the internal standard curve of bar codes, and transmiting the results through wireless transmission, The detection of fluorescent labeling even becomes informational and data-driven. Therefore, it becomes the favorite of point of care testing products.

However, we cannot simply say that colloidal gold test kit products are obsolete or outdated. From the perspective of Lepu Medical, Here we can use an analogy of a car to describe it: cars, SUVs, pickups and large trucks are all belong to vehicles, but they are used in different scenarios, their different performance and features cannot be mixed together for comparison.

In conclusion, the diagnostic kit colloidal gold product is not designed for precise quantification. It is a rapid testing product suitable for quickly determining whether a result is YES or NO. If the colloidal gold is rigidly designed for precise quantification, the product carries too much, it can only be said to be unnecessary.
