1. Symptoms of respiratory infections are similar, mixed infections

In recent years, respiratory infectious diseases have become a hot field of public health research. Children, the elderly, patients with malnutrition and chronic diseases are vulnerable groups. Respiratory infectious diseases are almost a health threat facing all mankind. Respiratory infections are diseases caused by pathogenic microorganisms invading the respiratory tract and reproducing. Divided by the throat, it is divided into upper respiratory tract infections and lower respiratory tract infections. The pathogens that cause respiratory infections mainly include viruses, bacteria, fungi, and atypical pathogens. Viruses mainly include influenza viruses, parainfluenza viruses, respiratory syncytial viruses, adenoviruses, etc. Common bacteria mainly include Haemophilus influenzae, pneumococci, and Staphylococcus aureus. Common fungi include Candida albicans, Pneumocystis Yersii, and so on. Atypical pathogens include mycoplasma, chlamydia, etc. The clinical symptoms of respiratory tract infections are complex. Their clinical manifestations are similar, and the same pathogen can cause multiple clinical symptoms. The same clinical symptom can be caused by multiple pathogens, so it is not possible to accurately diagnose infectious pathogens through clinical symptoms. At the same time, there is also a phenomenon of mixed infections in respiratory tract infections, which poses more challenges to clinical diagnosis.

2. PCR detection technology

There are various diagnostic methods for respiratory pathogens. The following is an explanation: In traditional detection methods, chest X-rays and blood routine tests have low sensitivity and specificity for bacterial and viral infections. The method of isolation and cultivation has high specificity, but the positive detection rate is low, the detection cycle is long, the collection of lower respiratory tract samples is difficult, the probability of contamination is high, and low-level viral infections are not easy to detect. Immunological specific antibody detection methods are greatly influenced by antibody dynamics. Pathogens can only cause respiratory symptoms when they invade target cells and actively proliferate. Therefore, antigen detection can be used to determine the pathogen, but the sensitivity of this detection technique is relatively low. With the continuous innovation, promotion, and application of molecular biology technology, PCR detection technology is becoming increasingly mature. Compared to traditional detection techniques, PCR detection technology is easier to detect pathogens of respiratory diseases. Meanwhile, it has high accuracy, short time consumption, and can identify the pathogenic microorganisms of mixed infections.

3. Free combination of Hecin reagents

Rapid differential diagnosis of respiratory tract infection is of great significance to identify pathogens, diagnose and treat respiratory infectious diseases, and avoid or reduce the harm to patients. Hecin  takes ensuring human respiratory health as its mission, always adheres to independent research and development, independent innovation concept, and deeply cultivates the development of respiratory infectious disease diagnostic reagents. Hecin Health Respiratory Pathogen PCR Detection Reagent is composed of individual tubes, which can be flexibly combined without any restrictions. These reagents can facilitate the simultaneous detection of multiple pathogens in a single sample, solving the problem of similar clinical manifestations and frequent mixed infections in clinical diagnosis.

The reagent has the characteristics of high sensitivity and simple operation, making it suitable for rapid diagnosis of respiratory pathogen infections and related diseases, and is compatible with fluorescent PCR platforms.

The product is made into freeze-dried powder reagents with strong stability, which can be transported and stored at room temperature, eliminating the trouble of low-temperature cold chain transportation and storage; And different testing items are made into different colors, making it easy to distinguish. The reagent operation is simple and convenient, and operators do not need complex manual packaging operations. Samples can be directly added and processed for detection.

In the post epidemic era, the detection of respiratory pathogens is receiving increasing attention. It is very important to quickly provide reliable pathogen detection results to clinical practice.
