Michigan\u2019s statutory term is operating while intoxicated, or OWI, although most people search for this issue as DUI. The prosecutor\u2019s ability to obtain the result depends on why the blood was drawn, what happened before the hospital transport, who requested the result, and precisely what the hospital disclosed.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-4338 alignleft\" src=\"https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-300x200.jpg\" alt=\"Hospital blood results in a Michigan DUI case reviewed for a warrant issue\" width=\"300\" height=\"200\" srcset=\"https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-300x200.jpg 300w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-1024x683.jpg 1024w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-768x512.jpg 768w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-1536x1024.jpg 1536w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-2048x1365.jpg 2048w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-1000x667.jpg 1000w, https:\/\/www.baronedefensefirm.com\/blog\/wp-content\/uploads\/2026\/10\/michigan-dui-hospital-blood-results-warrant-180x120.jpg 180w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>The controlling Michigan Supreme Court decision remains <em>People v.
