New blood test for rapid diagnosis of bacterial viruses, less anti-inflammatory drugs

Release date: 2015-03-27

Recently, the BBC issued a report saying that a study on Plos One believes that a new blood diagnostic test can help doctors find out whether a patient is infected with a virus or a bacteria within 2 hours. Scientists believe that this study will protect patients from unnecessary Antibiotics.

Although the research is still in the laboratory research stage, the scientists of this team have begun to study portable related equipment. Other experts who did not participate in the study found the research to solve a difficult problem. Scientists have begun to conduct more in-depth research.

This method prompts doctors to use the right drugs

When doctors need to determine which pathogens cause the patient's infection and decide which treatment to take, they often face many difficulties.

To determine the type of pathogenic pathogen, it takes several days if traditional methods of detection are used—these methods are usually sampled from the patient and then cultured in the laboratory for these pathogenic pathogens.

Detection of particles in the blood can sometimes provide clues, but some particles can originate from bacterial infections, or from viral infections, cancer, or trauma to the body.

This has led to the emergence of antibiotics (antibiotics are only effective against bacteria).

Contrary to this, because the test takes a long time, some patients who need antibiotics cannot use antibiotics in time.

Scientists from several medical centers in Israel have worked with MeMed to develop this new test method.

Using this method, scientists analyzed blood samples from more than 300 potentially infected patients who found that this method correctly detected bacterial or viral infections in most samples.

Mean's Eran Eden said: "This method of detection is very accurate. For most patients, in less than two hours, you can determine whether the infection is caused by bacteria or viruses.

This method is not perfect, nor can it replace the doctor's judgment, but it is better than many traditional detection methods currently used in clinical practice. ”

Detection principle: protein "label"

The principle of this method is that bacteria and viruses trigger different protein pathways when the pathogen infects the human body.

TRAIL is a novel protein that is very high in viral infections but rarely in bacterial infections. This new approach uses the protein and two other proteins, one of which has been used in current clinical testing methods, as an indicator.

Professor Jonathan Ball, a virologist at the University of Nottingham, said: "This research solves a real problem. It is very important to find possible infections as early as possible and to figure out whether the virus or bacteria are causing the infection.

“This makes clinical interventions more grounded and minimizes the use of antibiotics (such as those caused by viruses).

“It is necessary to further observe how long the accuracy of this method is.”

Household Wheelchair

Household Electric Wheelchair is an important Household Medical Equipment for the wounded, sick and disabled at home for rehabilitation, turnaround transportation, medical treatment, and outings. The Electric Wheelchair not only meets the needs of the physically disabled and the disabled, but more importantly, it is convenient for family members to move and take care of them. Patients, so that patients with the help of wheelchairs for physical exercise and participation in social activities.

Ordinary wheelchairs are generally composed of a foldable frame, front and rear wheels, left and right knee pads and footrests, left and right detachable armrests, handle brakes, seats, backrests with medical imaging data bags, bedpans, urine bag hooks, and electric standing. The hand-crank Rehabilitation Electric Wheelchair adds a hand-crank device on the basis of the ordinary wheelchair. On the basis of ordinary wheelchairs, the electric wheelchair adds an electronic power assist system, which reduces the physical exertion of the user. Based on the Electric Wheelchair, Folding Hospital Wheelchair adds positioning movement, standing movement, remote control movement and related Internet + assisted living.
