Odinga displayed his COVID-19 free certificate at the Kenya Medical Research Institute (KEMRI) where he was tested Sunday.
When he took the test on Sunday, he pleaded with Kenyans to follow suit.
"I took the COVID-19 test at KEMRI in Mbagathi earlier today (Sunday).
I took the opportunity to appeal to all Kenyans to go for testing," Odinga said, and stressed that "A COVID-19 certificate is becoming an important document as we continue battling the pandemic."
By June 14, Kenya had recorded 3,594 positive cases and 103 deaths.
