Error risks

Incorrect determination of the boundaries between serum fractions in the tube

In 2023, at the stage of preliminary preparation of the material, after centrifugation - separation of serum into fractions, aliquoting is carried out, that is, liquid is poured from the primary tube into several. In this case, the pipette for taking blood directly for analysis must be immersed at different depths, depending on the level of boundaries between the fractions. Often, at this stage, due to the human factor, errors arise that significantly reduce the quality of research. Poor quality laboratory testing in addition to the need to re-draw blood can lead to an incorrect diagnosis.

Scientists of NUST MISIS together with colleagues from BSTU named after V.G. Shukhov and NITSEM named after N.F. Gamalei are developing a robotic system based on machine vision, which, during the preparation of the material for blood analysis, will automatically determine the level of boundaries between serum fractions in the test tube. The development of scientists will speed up laboratory research and reduce the likelihood of errors. They plan to continue the research in order to organize the control of interacting robots, one of which must take a test tube with biomaterial from the tripod, move it to the work zone, wait for the plasma to be taken and install the test tube in the other tripod. The second robot must take plasma, dispense it in small tubes, get rid of the replaceable tip and install a new one. At all stages, where it is necessary to accurately position the robot over an object whose location is not known in advance, it is assumed to use machine vision.

Announcement of the home rapid diagnostics system for biological fluids

On October 25, 2024, representatives of MIPT announced the development of a home rapid diagnostics system for biological fluids. The set for home express diagnostics consists of a special color calibrator and a test strip, and a smartphone acts as a diagnostic device. It is the blocks on the color calibrator that allow the smartphone to read data from the test strip using the camera, regardless of external conditions. The developed system allows you to analyze up to 14 parameters of biological fluids (saliva, urine, blood), including: glucose, ketones, microalbumin, nitrites, hemoglobin and white blood cells.

A blood test has been developed showing which organs in a person will fail first

On December 6, 2023, American researchers from Stanford University announced the development of a new technology to predict organ failure during aging of the human body. The method is based on a blood test.

It is estimated that about one in five relatively healthy adults aged 50 years and older have at least one organ aging at a significantly accelerated rate. Thus, it is more likely that this particular organ will cause serious health problems. With information at their disposal about the rate of aging of individual structures, doctors will be able to prescribe the necessary therapy in advance to prevent diseases - long before clinical symptoms appear.

A blood test has been developed that predicts organ failure

As part of the study, experts estimated levels of almost 5,000 proteins in the blood of approximately 1,400 healthy people aged 20 to 90 years. Next, 858 proteins were identified that reliably predict the biological age of 11 key organs or systems: heart, adipose tissue, lung, immune system, kidney, liver, muscle, pancreas, brain, vascular system and intestine.

It turned out that in 18.4% of people aged 50 years and older, at least one organ aged much faster than others. Scientists have found that such people are at increased risk of the disease of this particular organ over the next 15 years. Moreover, about 1 in 60 people in the study had two organs that aged faster than the rest. Experts emphasize that the risk of mortality in this group is 6.5 times higher than in people without any intensely aging organs. It has also been established that in people with accelerated heart aging, but initially not showing active disease or clinically abnormal biomarkers, the risk of heart failure is 2.5 times higher than in people with a normally aging heart.^[1]

A device for collecting blood from a finger outside medical institutions came out

Test developed for a thousand tests of one drop of blood

In mid-January 2023, American researchers from the Stanford University School of Medicine spoke about the development of technology to obtain comprehensive information about the patient's health based on a blood drop test.

The project is led by Michael Snyder, head of the Department of Genetics. It is noted that usually at least 10 ml of samples are required for a comprehensive blood test, which makes frequent fences burdensome and uncomfortable for patients. Because of this, repeated tests can be delayed for months. At the same time, taking a small amount of blood from the finger will increase the frequency of tests, which will help medical workers to timely identify deviations from the norm that indicate the possible development of certain diseases. But research suggests that existing technologies, such as the dry spot method, allow a limited number of blood molecules to be analyzed and have problems reproducing results.

Test developed for a thousand tests of one drop of blood

Experts from Stanford University tried to bypass these restrictions. Scientists monitored the metabolic and immune responses of the body after eating. At the same time, thousands of changes at the molecular level were quantified, which were recorded in a particular person for one week. It is said that a blood sample with a volume of only 10 µL is enough to conduct such an analysis using a specialized Mitra device.

Snyder formed two companies to commercialize the study's findings. One of them, Rhythm, is working by March 2023 to find markers for the diagnosis and subsequent treatment of COVID-19, as well as chronic fatigue syndromes. Another start-up, Iollo, is preparing to bring a consumer test to market for more than 500 metabolites.^[2]
