The Rangers don't expect the results until Thursday.
Ogando gave up three home runs and allowed four runs total in 7 1/3 innings in the Rangers' 5-1 loss to Milwaukee on Tuesday night.
Ogando's velocity dropped during his start. He had his fastball at 94 mph in the first three innings, then saw it drop to mostly 90-91 mph the rest of the outing.
Ogando only has made 15 starts because of two stints on the disabled list, once for right biceps tendinitis and the other for right shoulder inflammation. He is 5-4 with a 3.47 ERA this season.
