In the field of modern medical diagnosis, point of care testing (POCT) is gradually becoming an important means of rapid diagnosis for many diseases due to its advantages. The integration of chemiluminescence technology has provided important assistance for the development of POCT. Among them, the acridine ester provided by Hubei Xindesheng Material Technology Co., Ltd. plays a key role in improving the sensitivity of POCT rapid diagnosis, providing more accurate and rapid detection methods for clinical diagnosis.

1、 Advantages of POCT

POCT， Point of Care Testing, which can perform clinical and bedside tests next to patients, is an important branch of the in vitro diagnostic industry (IVD). Compared with the large-scale experimental equipment in hospital departments, POCT has significant characteristics. It has a short turnover time and can quickly provide test results, saving valuable time for emergency treatment of patients. Easy to operate, no need for complex operating procedures, ordinary medical staff or even patients themselves can conduct testing under simple guidance. Moreover, POCT does not require sample processing, reducing the potential errors and contamination that may occur during sample processing.

2、 The rise of chemiluminescence technology

Chemiluminescence, as a form of immunodiagnosis, utilizes specific reactions between antigens and antibodies to measure the concentration of biomarkers in the body, in order to determine the state of the human body. This technology is widely used in various fields such as infectious diseases, cancer, pregnancy testing, etc. Chemiluminescent reagents have been rapidly promoted in clinical applications due to their outstanding advantages of high sensitivity, good specificity, high degree of automation, good precision, and high accuracy. They have quickly replaced enzyme-linked immunosorbent assay and have become the mainstream technology in the field of quantitative immunoassay.

3、 The fusion of advantages of chemiluminescence POCT

The application of chemiluminescence detection technology in POCT detection scenarios has formed chemiluminescence POCT, which combines the advantages of both. Its instrument is portable and can be operated in multiple locations, meeting the detection needs in different scenarios. There are a large number of instruments with diverse functions, which can be customized for different testing projects. Meanwhile, chemiluminescence POCT focuses on clinical care, and experienced doctors can make accurate judgments based on the test results.

4、 Possible technical issues

However, chemiluminescence technology is quite challenging. The concentration of the detected substance is extremely low, usually in the range of μ g/L-pg/L, which requires high precision for the entire detection system, and the instrument and reagent system need to be closed to ensure the accuracy of the detection results. The entire detection process involves numerous steps, making it difficult to achieve automation. In addition, chemiluminescence technology integrates various cutting-edge technologies from disciplines such as biology, chemistry, physics, and optics, and any problem in any link may affect the detection results. The technical difficulty of fully automated chemiluminescence immunoassay itself is relatively high, requiring high-precision instruments and high-quality reagent matching.

5、 The key role of Xin Desheng acridine ester

Among the technologies used in POCT chemiluminescence, acridine ester direct chemiluminescence has attracted much attention. Hubei Xindesheng Material Technology Co., Ltd., as a professional supplier of biochemical raw materials, has advantages in providing acridine esters, which empower the rapid diagnostic sensitivity upgrade of POCT. Acridine esters can directly emit light in chemical reactions without the need for enzyme catalysis, with a fast reaction rate and the ability to quickly produce strong chemiluminescence signals. This enables clear signal capture even when detecting low concentration biomarkers, improving the sensitivity of detection. The purity of Xinde Sheng Acridine Ester is high, with low impurity content, which reduces the interference of impurities on the detection results and further improves the accuracy and precision of the detection. Its good stability ensures reliable performance under different environmental conditions, providing stable reagent support for POCT detection. In the detection of infectious diseases, the use of POCT chemiluminescence reagent of Xinde Sheng acridine ester can quickly and sensitively detect extremely small amounts of pathogen markers, helping to make timely diagnoses.
