DUI Blood Tests
Nashville DUI Blood Test Attorneys
At May McKinney, we have a saying that there is only one organization you should give blood to — the Red Cross. Although law enforcement may pressure you to submit to a DUI blood alcohol test, doing so is usually not in your best interests.
If you have already taken a DUI blood test, however, do not give up hope. The test results are not infallible. In fact, in today's world of advanced forensic science, there are more defenses against DUI charges than ever before.
Serving clients in Nashville and throughout Tennessee, our DUI defense attorneys at May McKinney know what it takes to challenge blood test evidence and other aspects of a DUI, BUI, or underage DUI case. We have almost 80 years of collective legal experience and frequently represent clients in state, federal, and juvenile courts across the state.

Challenging Blood Test Results
May McKinney has the skill and legal knowledge you are looking for in your case. In taking on a new DUI case, we will investigate every aspect of the blood draw and determine if there are any flaws in the prosecution's case.
Such flaws may include:
- Your blood was drawn by an unlicensed person.
- The testing equipment was not properly calibrated.
- Your blood was not drawn within the correct timeframe.
- Your blood sample was not stored or preserved correctly.
- The sample was fermented, resulting in a higher blood alcohol content (BAC).
- The proper chain of custody procedure was violated.

I appreciate absolutely everything that you and your team have done for me. I could not have made a better decision than to have your representation during this horrific time in my life. Along the way, I feel like I was educated about the process and felt at ease with every step. The due diligence that was done on your behalf was top tier and goes without saying, simply awesome! The only regret I have is not coming to your first. You have my full support of referrals to anyone I hear that needs a great defense team in their corner, because I sure did! Again, Thank you!

There are precious times in our lives when we are blessed with people who make a difference.- Nathan

This was my first experience ever being accused of a crime and I was very nervous and scared. Rob and his staff were incredibly helpful, answering all of my questions and putting my mind at ease throughout the process. In the end, we were able to get everything dismissed successfully. Although in the grand scheme, my case was a relatively minor one, Rob always was there to help and it was clear that his knowledge and experience would be hard to find anywhere else. I would absolutely recommend Rob and his team to anyone looking for a defense attorney.- SA

In a nutshell, all of the glowing reviews that I read on this site are 100% spot-on. I had a DWI case reduced to reckless driving. Rob is a fighter and would have battled for a full dismissal if I had requested him to but after some discussion I concluded that accepting the lesser charge was the right move for me. Furthermore, Rob was able to file a motion and get the judge to dismiss my probation obligations once I finished the mandatory classes. It was the best possible result for me. I also need to mention that Karen, the front end of the firm, is spectacular and plays an important part in the firm's success and client experience. She responds to communications promptly and keeps you informed of what's happening as required while Rob and Shyanne stay busy getting the legal work done. Seriously, if you're searching for representation and nervous because you don't know who you can trust and rely on, just stop. I promise you these reviews you've been reading (just like I did before I contacted the firm) are accurate and you can quickly take some of the weight off of your shoulders by having a meeting at May & McKinney and retaining them for your case.- D.T.

As a LEO wife, I was served with a frivolous OP from an estranged step family member. With the possibility of my husband not being able to process any firearms in our household, Mr McKinney's understanding the severity of the situation, Rob took the time to investigate and prepare for the hearing. With that said, Rob absolutely destroyed the petitioner and witnesses on the stand. It was worth the time, money and stress to see Rob in action. If the need ever arises in the future, Rob will always be our first call. You cannot go wrong putting your trust in Mr. McKinney.- Tara

The case came during my senior year of college. It was the scariest moment of my entire life. I felt my career was over before it even started. I chose McKinney Law Firm because they are the Best of the Best. To have a prepared and knowledgeable defense, in a room where you feel guilty until proven innocent, is invaluable. Roger T. May's no non-sense approach was deliberate and strategic. The results of the case were better than I could have ever imagined. After the case was over, I went on to land a lucrative job, travel the world, and have had a very successful career. I truly believe McKinney Law Firm gave me a second chance at life. I am forever grateful for the team's care, urgency, persistence, and professionalism during a very difficult time. "Because I knew you, I have been changed for good." Thank you.- -Satisfied Client

So I was charged with schedule 2 simple poss and paraphernalia. His excellence got it dropped to a simple paraphernalia charge with unsupervised probation! It was a mandatory 30 days in jail to basically nothing but fines. Well worth every penny. If you need a lawyer call this guy immediately. He'll do everything he can with a smile to give you the best results possible. Thank God for Rob Mckinney!!!- Daniel Himes
