There are certain assumptions breathalyzers make as to the average person's ratio of alcohol in their breath compared to alcohol in their blood. The basic problem is that no person is actually average and the conversion factors not only vary between people, but change over time for a given individual. The only true way to determine blood alcohol content is to draw and analyze the blood. For more on the subject, see the related link below. ADDED: The name "Breathalyzer" has become a common slang term loosely applied to describe any alcohol-testing device. If you are referring to the hand held 'screening devices' used by officers on the street - they are accurate enough for probable cause to administer further tests to you to determine if you are legally impaired. If you are referring to the testing device that is used at police stations or in alcohol testing mobile vans - after long usage and many court challenges, they are considered to consistently be accurate enough for their results to be widely accepted nationwide as prima facie evidence of intoxication/impairment.
