Coronavirus test kits are proving unreliable in light of recent outbreaks

Covid-19 test kits apparently aren’t always 100% reliable, which is compounding the problem of its spread across continents, the Wall Street Journal says in this explainer video (watch, runtime: 03:37). There are several factors and variables that can affect the test kits’ efficiency in delivering accurate results, such as how the swab is inserted into your nose or throat and how long the samples take to arrive at the lab, says Singaporean biomedical research lab Biopolis CEO Sidney Yee. Results could also be affected by which stage the virus is at, Yee explains. Medical professionals are now using other diagnostic methods, including chest scans, concurrently with the test kits to yield more conclusive results.
