STATES CHRONICLE – Who would have thought that a USB stick would ever help at diagnosing a disease? Believe it or not, now this is possible. Scientists have developed such an innovative way of diagnosing HIV patients by using a USB stick. The spectacular tool was designed by experts to form DNA Electronics and Imperial College London.
The device uses a drop of blood to discover the dangerous virus. After that, it generates an electrical signal that can be transferred to a computer or a laptop, transforming into a readable message. This new technology is indeed amazing. This disposable device is very handy for those patients who need to monitor the evolution of the disease after taking their treatment.
What is more, the USB stick can also enable HIV patients to become easy to be checked when they are in remote locations. A new study concerning this problem was recently published in the Scientific Reports magazine. The study proves that the result of the test is generated in less than 30 minutes, being very accurate.
This unusual type of technology is bound to establish the amount of virus present in the bloodstream of the patient. Thus, the USB stick undergoes a significant task for HIV patients who need constant monitoring. Other tests which were also designed to detect HIV in the bloodstreams were taking three days until they displayed the results. What is more, to complete the test, the patient needed to send a blood sample over to a lab to be processed.
Other regions of the world where the HIV infections are countless do not even benefit from such advanced technology. The cure which is used in the present to treat HIV patients is capable of generating a decrease in the levels of the virus to almost zero. Unfortunately, sometimes the virus may develop resistance to the cure. Thus the treatment stops giving satisfactory results.
If the virus has become immune to the anti-retroviral treatment, this could indicate an increase in virus levels. Moreover, when patients use the new technology to measure viral levels, they enable healthcare personnel to verify if every patient is correctly distributing their treatment. Patients should not stop their treatments because the virus will immediately be fueled to develop resistance to the drugs.
