"Tests and Prevention That Can Save Your Life" is the topic of Saturday's Deseret Morning News/Intermountain Healthcare Hotline. From 10 a.m. to noon, Dr. Scott Hansen and Dr. Ted Adams, both of the Health and Fitness Institute at LDS Hospital, will take phoned-in questions. All calls are confidential. From the Salt Lake area, call 236-6061. Elsewhere, the toll-free number is 1-800-925-8177, but the numbers are only operational during the hotline hours.
