Houston - (AP) - Former first lady Barbara Bush is being released from a Houston hospital where she's been undergoing tests since she was admitted last weekend.
Family spokesman Jim McGrath said the time of her return home today isn't known.
The 84-year-old wife of former President George H.W. Bush went to Houston's Methodist Hospital on Saturday after not feeling well for about a week.
She's been described as not being in any pain or danger.
Bush had heart surgery in March 2009 for a severe narrowing of the main heart valve.
She also was hospitalized in November 2008, when she underwent surgery for a perforated ulcer.
