Blood Tests May Not Be As Accurate As You Think

There is a commonly held belief that DWI blood tests are more accurate than breath tests and the results cannot be challenged. That is simply not the case. Blood test results may be flawed, and showing the flaws can be the key to a successful DWI defense strategy.

At The Law Office of Kelly F. Pittl in San Antonio, Texas, we know how to look for flaws in blood test evidence. We are committed to positive results in drunk driving defense cases, so we investigate thoroughly to find any opportunity to have evidence thrown out or to get the entire drinking and driving case dismissed.

Where Blood Tests Can Go Wrong

There are various stages at which blood tests can go wrong, and the first is when the blood is drawn. Any contamination can skew the results of the test, so it is critical that proper procedures are followed when blood is taken. Many of the people conducting these tests may wear lab coats, but actually have very little training. We will look carefully at this stage in the process to determine if there is reason to believe the test results were contaminated.

How was the blood transported from the site of the blood draw to the testing equipment? How was it stored? How much time passed? Any number of errors can be made during this transit phase. These errors could lead to inaccurate results.

An attorney must also review the manner in which the blood test itself was conducted. We will investigate to determine whether the gas chromatograph or other machinery was properly maintained and properly used. Machine error or human error at this stage could cause false positives, and if we find indication of such, we will request the evidence be thrown out.
