Robin Roberts returned to the "Good Morning America" set Thursday for the first time since undergoing a bone-marrow transplant.

It was a test run.

"What a thrill to be back at GMA's Times Square Studio this morning and see the best folks in the world, my GMA family," ABC News quoted the 52-year-old journalist as saying. "I can't wait to get back to the anchor chair in a few weeks."

According to E! News, Roberts, her head bald from her treatment, told co-anchor George Stephanopoulos in an interview that after conferring with her doctors she'd be doing a series of "dry runs"to adjust her body again to the rigors of her job.

That means rising at 4 a.m., arriving at the studio by 5 a.m. and getting used to the studio environment she left behind last August when she announced she was taking a medical leave of absence to be treated for myelodysplastic syndrome, a blood and bone marrow disease.

"My skin is very sensitive and so we have to see how it reacts to the studio lights. My vision is still a little blurry from the treatment," the TV veteran said. "All of this is getting better day by day so that is the next step."
