If you've been arrested for a DUI in Troy, Michigan, and you either refused a breath test (see Implied Consent Law) or the police selected the blood test for you, a blood sample will be taken at a hospital or other medical center. The blood draw could be performed by a doctor, nurse or phlebotomist, and the police officer must be present. The police officer must provide the testing kit, which will contain two vials.
In a Troy DUI case, both vials must be used, because one is tested by the MSP crime lab, and the other is preserved for independent blood testing.
Once the sample is collected, it will be transported to the MSP crime lab in Lansing by first-class mail. This could be a process that takes several days, and the time/dates will be listed on the paperwork, which should be demanded by your attorney.
Although the crime lab is careful to maintain an exact temperature on the blood samples once they are received, variances in temperature during transport can provide effective fodder for cross-examination of the laboratory technician who tested the sample.
