I did not have that much to drink but the blood test results are high. How can that be?

There are many factors that will affect results of a blood test.  Skillful Los Angeles DWI lawyer will help you analyze it.  For example, sometimes,  police agency relies on the analysis of blood alcohol concentration from the hospital.  The hospital often will analyze alcohol from serum and not from whole blood.  That technique overestimate the alcohol concentration by 18-25%.  That means that a .076% BAC tested in Serum will show as .09% BAC.  That discrepancy becomes more significant at higher blood alcohol level which strongly affect settlement discussions.  A .16% BAC whole blood will register as .18% BAC in serum.  There are several reasons why serum BAC testing is higher.  One of the reason is based on solubility of alcohol in water.  Serum excludes certain solid particles from blood but it does not exclude water.  Because alcohol is soluble in water, it stays behind after the separation, making concentration of alcohol in serum higher then it was in whole blood.

A DUI Los Angeles attorney will help you prepare such defense.  This however, is only an example of why blood alcohol level can be higher when tested.  Other examples include presence of mouth alcohol during breathalyzer test and fermentation because of improper storing.  Clever DUI attorneys in Los Angeles will flash out all such issues during negotiation or cross and help you defend your case.
