Bamba was originally diagnosed with COVID-19 on June 11.
The Magic's human performance staff and team physicians advised the 22-year-old to undergo the testing.
Bamba first revealed his COVID-19 diagnosis to The Athletic's Josh Robbins earlier this month. He said the illness prevented him from working out at the team's training facility during the season's suspension and negatively impacted his conditioning.
After arriving at the NBA campus, Bamba recorded false positive test results, forcing him to quarantine in his room and miss some of the team's practices.
He's played in two games during the restart but has missed Orlando's last six contests.
The long-term effects of COVID-19 are still generally unknown. However, Boston Red Sox pitcher Eduardo Rodriguez announced in July he will miss the 2020 Major League Baseball season after an MRI revealed he had myocarditis - inflammation of the heart muscle - following his own COVID-19 diagnosis.
Orlando opens its first-round playoff series against the Milwaukee Bucks Tuesday.
