Alcohol Blood Test Defenses for Michigan DUI Cases


Currently, the Michigan State Police Forensic Science Division in Lansing is responsible for the evidentiary testing of all blood samples for the presence and amount of alcohol and drugs for all drunk and drugged driving prosecutions. This alcohol blood test is often considered to be very strong evidence for the prosecution and most attorneys believe that their results cannot be effectively challenged. That is isn’t true for our team of attorneys.

There are several avenues of attack on blood testing that only a drunk driving specialist attorney will be able to successfully use.

Pre-Draw Issues

The prosecution must call the nurse or doctor to testify that the manner in which the blood was drawn was proper. The following list includes several issues that must be challenged:

  • Were the proper blood collection tubes and color stoppers used?
  • Were the blood collection tubes expired and too old?
  • Did they contain the proper chemicals to be mixed with the blood?
  • Was the proper needle size used?
  • Was the needle inserted into the vein correctly?
  • How are they sure there was no hemolysis (break down of red blood cells which can create alcohol fermentation after blood draw)?
  • Was the blood specimen tube free from contaminants during collection to be free from candida albicans (a bacteria that will create alcohol via fermentation after the blood draw)?
  • Was the correct non-alcoholic swab used?
  • Was the person who drew the blood properly trained, qualified and operating under the supervision of a medical doctor (unlike a fire department paramedic whom by law isn’t qualified).
  • Was there the proper medical environment used as a location to draw the blood?
  • Was the blood collection tube properly inverted after collection of the blood?
  • Were all persons in the chain of custody of the blood properly trained to handle the blood specimen?
  • Was there a possibility of bacterial contamination during the collection?

Post Blood Draw Issues

The MSP-FD forensic scientist must testify to properly admit their results. Only a specialist with a very good understanding of how they test for alcohol or drugs in blood can effectively cross examine them and find a reasonable doubt including the following issues.

  • Did they follow their department rules to the letter when testing the sample?
  • Did they use proper internal standards (necessary for comparison and quantitative analysis)?
  • Were sufficient blanks run, to ensure the alcohol from one sample isn’t improperly counted in the next sample (carryover)?
  • Where the reports the testing instrument created (chromatagrams) interpreted properly?

The MSP-FD is underfunded and undermanned. Due to these conditions they believe they can cut corners, modify and eliminate proper procedures. The lab must be challenged on these non conforming practices.

Why Hire A DUI Attorney From The Law Offices of Barton Morris?

Challenging blood test results must be done with effective pre-trial motions and effective cross examination of the arresting police officer, forensic scientist and phlebotimist at trial.

Our attorneys are trained and experienced with making all of the above arguments effectively. Most criminal defense attorneys are not. In fact, Barton Morris is Michigan’s only forensic lawyer-scientist, meaning he has undergone extensive forensic training in labs and earned a certification few in the country possess. It makes him uniquely qualified to handle DUI cases, as every DUI case has a chemical test, which is forensic evidence. Barton trains his attorneys so they not only get his knowledge, but refer to him in all DUI cases.

Barton Morris graduated from the Axion Lab’s Hands On Forensic Chromatography Course where he was taught the theory behind blood alcohol testing and learned hands on how to prepare a sample and test blood for alcohol using an actual gas chromatograph with a flame ionization detector exactly as performed at the Forensic Science Department of the Michigan State Police. Barton also learned how to perform regular maintenance upon the instruments including changing the columns and septums.

The Hands On GC Course allowed Barton to have the unique experience of performing the same blood alcohol testing just as is performed at the MSP-FSD. This specialized training is invaluable when fighting a blood alcohol OWI prosecution. Further, Barton Morris now owns the same Chromatography Thermo Quest software used by the MSP Forensic Science Division to perform an independent analysis of the raw data that’s generated in the testing of each blood alcohol and/or drug OWI case in the State of Michigan, right in his own office.

Barton Morris and his team have the knowledge, equipment, expertise and practical experience to effectively fight a blood alcohol or drug OWI case that consistently leads to great results for his clients.

Barton was amazing and I could not have had the positive outcome without his guidance. His team is prompt and great to work with. He even called while out of the country on vacation, which I feel shows he went above and beyond what someone might expect from their attorney. Experienced and cares! I would highly recommend Barton!

Very professional. I came and spoke to Barton Morris about my situation and my case. I asked him if he was willing to help me. He asked about the details and my background and history. He give me a positive confidence he can help me and my odds. His price is reasonable. He’s not one of those hole in the wall lawyers who treat you as a number. You are a human being with a personal life. You treats you as a valued client no matter how big or small the case.

I had Mike Norman as my lawyer for a case. I just wanted to come on here and thank him for doing his best for me. I am grateful during this stressful time. I’ve used Barton Morris as a lawyer about 11 years ago and he was awesome which is why we came back. I do recommend!

Extremely knowledgeable and very helpful when it comes to navigating the complicated nature of cannabis businesses in Michigan. I met with Barton where he answered all my questions about the pre-qualification application, and was prompt in answering subsequent questions through email after the meeting was completed. I certainly plan to continue utilize Barton’s knowledge in the future.
