Skin test could save patients’ lives

Scientists have used skin sensors to accurately detect antibiotic levels in patients.

They say the method, which uses microneedle biosensors, has the potential to help the sickest of patients by identifying how they are responding to treatment.

Researchers at Imperial College London say they have shown for the first time how the sensors can be used to monitor the changing concentration of antibiotics.

The small, non-invasive patches worn on the skin can detect the levels of medication in a patient’s system, matching the accuracy of current clinical methods.

Scientists believe the technology could change how patients with serious infections are treated by showing how quickly their bodies use up medications they are given.

They add that, if future development and testing proves successful and the technology reaches the clinic, it could help to cut costs for the NHS and reduce drug-resistant infections.

It could also improve treatment for patients with lifethreatening infections.
