Physicians in California, US have been using lung scans from 4DMedical to gain better insights into the effects of long Covid, report Reuters. The lung scans use existing hospital equipment to identify high and low lung ventilation in long Covid patients. The company uses a video sequence of approximately 20 seconds of the patient breathing naturally, which facilitates mathematical calculation of the motion and the airflow in and out of the lungs. The technology also uses algorithms and mathematical models to convert sequences of X-ray images into quantitative data. The scans reveal evidence of lung damage not seen on a CT scan or X-ray, according to 4DMedical chief clinical adviser Dr Ray Casciari.

OraSure Technologies is set to receive up to $13.6m funding from the US Biomedical Advanced Research Development Authority (BARDA) to support the company in obtaining 510(k) clearance and Clinical Laboratory Improvement Amendments (CLIA) waiver for its InteliSwab COVID-19 rapid test. The test has received EUA for point-of-care, prescription, home and over-the-counter settings in the US. It uses an integrated swab for self-collection of a sample from the lower nostrils and delivers results in less than 30 minutes without the need for external instruments, a smartphone or laboratory analysis.
