Presidential candidate Volodymyr Zelensky has already received blood test results and made them public.
"Spring has come, and we did it together," he wrote on Facebook, posting the relevant photos of test results.
No traces of psychoactive substances have been revealed, according to the documents.
The clinic also informed it had additionally sent a sample of Zelensky's biomaterial for examination to an independent laboratory of the network of clinics HM Hospitales (Spain).
As UNIAN reported earlier, on April 3, Zelensky declared his readiness to come to the debate with Poroshenko ahead of the runoff, however, he voiced a number of conditions. In particular, he said, the debates should be held at the Olimpiyskiy Stadium in Kyiv, "before the people of Ukraine", and with all TV channels being able to air the event live, while both candidates must undergo a medical exam and prove to the people that there are "no alcoholics or drug addicts" among them.
Poroshenko agreed to hold the debate with Zelensky at the stadium.
On April 4, speaker of the election headquarters of incumbent Ukrainian President Petro Poroshenko, Oleh Medvedev, said that Poroshenko had invited Zelensky at the Olimpiyskiy health center to pass the relevant tests.
In turn, Zelensky's headquarters rejected a proposal to take a blood test at the health center and announced he would come to a private lab.
On Friday morning, April 5, Zelensky passed blood tests at a private clinic Eurolab.
Presidential candidate Petro Poroshenko passed the relevant tests at the Olimpiyskiy health center.
