From the article:

“Researchers in the US and China have worked to replace PCR tests for COVID-19 with a process called LAMP (Loop-Mediated Isothermal Amplification). The basic idea is the same: it multiplies the number of particular viral genes in a sample so they can be observed. But LAMP is designed to be much simpler, faster and cheaper than PCR. LAMP tests can be conducted in a simple heat bath, meaning almost any lab or hospital could theoretically do the test.”
