Two types of conventional immunoassays, called competitive and sandiwich immunoassays, have been widely used since the first immunoassay was introduced in 1959. The conventional immunoassays are so sensitive that they can quantify trace levels of antigens in various samples. However, performing conventional immunoassays through complex procedures has several significant drawbacks. These include (1) excessively long incubation periods for the immunoreaction, (2) time-consuming multiple washings after incubation, and (3) limited applicability of competitive and sandwich immunoassays.
Recently, Luminescence MD, LLC developed an advanced immunoassay system called All-in-One immunoassay to address the shortcomings of conventional immunoassays. Below are the benefits of using the All-in-One immunoassay:
1. It is a fast and user-friendly method that does not require washing and has a short incubation time.
2. It offers high sensitivity and selectivity, making it a dependable tool for detecting target antigens.
3. It is a cost-effective option, particularly for large-scale testing.
4. It has the capability to quantify all antigens, regardless of size, which is not possible with conventional immunoassays.
5. It has the ability to accurately diagnose human diseases by consecutively or simultaneously quantifying multiple antigens in patient samples.
Due to its numerous advantages over conventional immunoassays, the All-in-One immunoassay has a wide range of applications for monitoring and supporting health across various fields. These include humans, animals, plants, and even the environment. The characteristics and roles of the All-in-One immunoassay compared to competitive and sandwich immunoassays are shown in Table 1.
