New paper strip test can detect heart failure
Scientists from China have developed a new paper strip test that could allow heart failure patients to monitor their condition at home.
A study on the new strip, conducted by researchers at Xi’an Jiatong University, was published in the journal ACS Nano.
The strip is fairly easy to use and only needs a small blood sample of 10 microliters to test if the cardiac biomarker ST2 is present in the sample. If it is present, a blue dot glows on the strip, and if BNP is present, a green dot glows.
If a patient’s heart failure is worsening, the colors on the strip will intensify. An accompanying smartphone app can analyze results and send data to a remote physician, who can then adjust treatment accordingly.
