Robin Roberts, co-host of ABC news’ “Good Morning America” talk show, completed one of several off air test runs Thursday. These test runs were approved by her doctors. They will also give Roberts the opportunity to see how her body will react to the socially rich environment of the news studio.

In an ABC news statement Roberts was quoted as saying “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”.

The fifty one year old Roberts routine for her day starts when she gets up at 3:45 a.m. and gets to the studio at 5 a.m. Thursday was the first visit back to the “Good Morning America” studio since she took medical leave over three months ago.

Roberts suffers from myelodysplastic syndrome, MDS. It is a rare blood disorder. Her sister, Sally-Ann Roberts, donated cells that were injected into Robin during a five minute procedure back in September.
