Performance-enhancing drug test provides immediate results

"The most popular method to test for meldonium in the blood is gas chromatography with mass spectrometric detection," says Olga Mezentseva, post-graduate student at the TPU Institute of Natural Resources.

"This method involves using rare and expensive reagents, and the sample preparation process is also expensive. Our reagents are affordable, and therefore inexpensive. The electrodes used in the device are standard and fit most voltohmmeter devices."

The analyser is easy to use, thanks to an intuitive interface, and most importantly, it is compact and does not require additional software. Similar devices require post-processing of results with a computer on which special software is installed. The PTU device display provides test results immediately.

"Initially, our research team developed a technique for rapid meldonium testing in the athlete's body, but now we have set ourselves a broader task—to develop devices to test athletes for different types of drugs," says Olga Mezentseva.

She notes that the basis of such a device is an electrochemical technique that detects a substance with electric current exposure. This technology has long been used by TPU scientists for identifying many organic substances. To fine-tune the device to test for different banned drugs, a laboratory staff member can change electrodes in the device.

"Firstly, a prototype of our device was presented at the U-NOVUS forum for young scientists. Now, we are carrying out metrological evaluation of the technique with colleagues. We plan to develop the chosen direction, and improve the device. By the end of 2016, we intend to create the first prototypes of universal electrochemical analysers," says Olga Mezentseva.
