Many opine that DUI blood test is more reliable then DUI breath test for variety of reasons, including, partition ratios, margins of error and other factors that affect the difference between alcohol concentration in blood and breath.  Despite supposed reliability of blood test, blood test errors can be common because blood can ferment when improper preservation techniques are used.
