Abu Dhabi has updated its protocols for visitors and residents.
Abu Dhabi Emergency, Crisis and Disasters Committee announced that starting Saturday, i.e. September 5, residents and visitors can enter the emirate of Abu Dhabi within 48 hours of receiving a negative PCR or DPI test result.
DPI test results no longer require a prior PCR test.
Earlier, a person had to undergo both tests to be allowed into Abu Dhabi.
What are these tests?
A PCR test, short for Polymerase Chain Reaction, is conducted using a nasal swab and used to amplify the DNA sample and then detect specific antigens.
A DPI (Diffractive Phase Interferometry) test, on the other hand, is a laser-based test that uses blood samples to examine the virus. It allows the health authorities to carry out large-scale screening within a few seconds.
