Biochip detection can detect pathogens from saliva for up to 2 hours.

A biochip test that quickly determines the pathogens of respiratory diseases has recently been used - just two hours to determine the type of bacterial infection, six to 240 times faster than traditional methods.
beijing Boao Jingjing Biotechnology Co., Ltd.'s technology is particularly valuable for the treatment of respiratory diseases in children and the elderly because it saves time for treatment and avoids delays.
diseases that affect human life expectancy, respiratory diseases are often overlooked.
, the respiratory tract is connected to the outside world and is easily infected, especially in the elderly and children, with low resistance and frequent infections.
world's top 10 causes of death, released by the World Health Organization in 2013, ranked third in lower respiratory tract infections.
2011 incomplete statistics from the Chinese Centers for Disease Control and Prevention show that the mortality rate from pneumonia among children under 5 years of age in China is 184 to 100,000 to 1,223 per 100,000.
the high rate of death from respiratory diseases is that pathogens cannot be identified quickly and accurately and treated in a targeted manner.
traditional diagnosis and treatment, patients need to take blood tests to infer whether it is a virus or bacterial infection.
After determining a bacterial infection, doctors considered using antibiotics, but the most distressing problem came: many people use an antibiotic after the disease has not improved, or even more serious, can only be replaced with another antibiotic to continue treatment, causing unnecessary pain and economic loss to patients.
reasons for this, traditional methods can not quickly and accurately determine the types of pathogenic bacteria, doctors usually use broad-spectrum antibiotics, if pathogenic bacteria are not sensitive to the drug, need to change drugs.
, most clinical treatments in China are still in the stage of empirical antibiotic application, and there is a greater blindness in the use of advanced antibiotics.
To identify pathogens, clinically commonly used methods of identification are bacterial culture, which usually takes about a week to obtain results, while special strains take longer to identify and delay the treatment of patients with severe respiratory infections.
recent years, with the rapid development of molecular biology, pathogen diagnosis and molecular biology technology closely combined to form a pathogenic molecular diagnostic technology.
For pathogens difficult to culture, long detection cycle, low diagnosis rate and other urgent problems to be solved, Boao Jingjing introduced a respiratory pathogen nucleic acid detection system, through the detection of patient sputum, 2 hours can determine the type of bacterial infection, 6 times faster than the traditional detection methods to 240 times, completely breaking the limitations of traditional detection.
addition, by virtue of its advantages of speed, accuracy, sensitivity and specificity, it has a prominent role in pathogen diagnosis, providing reliable technical support for the diagnosis, treatment and research of bacterial resistance mechanisms for lower respiratory tract infections.
accurate early diagnosis of pathogenic bacteria, is the key to cure patients, choose the best test method can shorten the course of treatment, save money.
respiratory pathogen nucleic acid detection system can be a good solution to the problem of wrong medicine, let us eat less wrong medicine.
3-year-old patient, Ming Ming, was admitted to hospital with pneumonia two days later without any improvement, but also developed breathing difficulties and other symptoms, can only use a ventilator to support life.
The child is in critical condition, the hospital used the highest level of antibiotic treatment, the condition is still not improved, and then the use of respiratory pathogen nucleic acid testing chip test, 2 hours later, according to the test results, the doctor used antibiotics for pathogenic bacteria, the daily cost dropped significantly, the disease has been well controlled.
three days later, the child resumed self-breathing, entered the general ward for observation, and soon recovered and was discharged from the hospital.
, according to Gao Zhancheng, director of respiratory medicine at Peking University People's Hospital, respiratory pathogen nucleic acid testing products have been developed since 2006.
clinically proven, this product can be efficient and convenient detection of patients, only one mouthful of sputum, within 2 hours can be a one-time rapid detection of 8 common lower respiratory tract pathogens.
It is understood that the system can be used in addition to respiratory pathogen detection, but also can be applied to digestive pathogen detection, wound infection pathogen detection and other clinical testing directions, for the rapid diagnosis of infectious diseases, accurate treatment and response to major public health emergencies provides an effective tool.
industry insiders pointed out that if the technology can be popularized on a large scale, not only can avoid the window period of misdiagnosis, but also can accurately identify the cause, targeted drug administration, to avoid drug abuse.
