Why does it take so long to get blood test results back from a DUI?
Blood test results for a DUI can take a long time due to several factors. First, samples must be properly collected, stored, and transported to a lab, which may have a backlog of tests. Additionally, the testing process itself can be complex, requiring precise analysis and verification to ensure accuracy. Finally, legal protocols and the need for confirmatory testing can further extend the timeframe before results are reported.

Explain a hemolyed sample?
I am assuming your question is in regards to a blood sample. Hemolized blood samples means that the red blood cells have been destroyed. This can happen in several ways, i.e. using a needle that is too small with high pressure while drawing the blood sample or even spinning the blood sample too long in the centrifuge prior to sending for lab testing. The hemolized red cells break open releasing the hemoglobin from within.
