Tag: Blood Samples



Reader’s Question:

I am so curious as to how they draw blood in a DUI investigation in Jacksonville, Florida. Does the blood have to come from the arteries or veins?

The blood samples from people accused of DUI in Jacksonville, Florida are commonly withdrawn from the vein rather than from the artery. But the blood alcohol content (BAC) of blood taken from the veins could be quite different from the BAC of blood taken from the arteries in a subject at a given time. It is also the blood in the arteries that carry alcohol into the brain, resulting in intoxication; thus, analysis of blood samples taken from the veins can be misleading.

As a matter of fact, researchers have concluded that using a single blood sample taken from the veins to determine an earlier BAC produces a result that is equivalent to a wild guess. In a related article published in 1984, a lot of scientists have measured comparative BAC levels in the breath, venous blood and arterial blood of people who had consumed known quantities of alcohol. The scientists noticed that BAC of blood taken from the artery was higher than that of blood taken from the vein during the absorptive phase that is, while the alcohol was being absorbed by the body. Arguably, the blood samples taken from the veins had higher BAC levels than the blood samples taken from the arteries during the elimination phase of the blood-alcohol curve. Therefore, the blood sample take from the vein during the elimination phase would be analyzed as having a higher BAC than is in fact being carried to the brain.






Reader’s Question:

Finding a good defense attorney seems to be so difficult after I have been charged with DUI here in Jacksonville, Florida. Could you please tell me how do I find a good DUI attorney?

I understand that it can be difficult to find and retain a good DUI attorney in Jacksonville, Florida, especially if many attorneys are not experienced and fully capable of handling DUI cases. You have to make sure that you make the right inquiries so that it could help in finding the best DUI attorney. The very first thing that you would have to do is to make sure that the fees are thoroughly explained and in writing and find out if it already includes the administrative hearings held by the DMV. You also have to know if the fees include cost of expert witnesses and other requirements for the trial.

Then you would also have to make sure that the attorney is a DUI specialist which means that the attorney exclusively focuses on DUI defense. Find out also if the attorney has any record of complaints from the State Bar and if the attorney is Board-certified by the National College for DUI Defense. You might also want to ask if the attorney would have the blood samples reanalyzed by a lab. For this matter, the DUI attorney can call technical expert witnesses in police procedures and blood/breath analysis.
