Getting Blood Results After A DUI

Being arrested for a DUI (Driving Under the Influence) can be a daunting experience, especially when chemical tests like blood draws are involved. In DUI cases, law enforcement often uses blood tests to determine an individual's blood alcohol concentration (BAC). However, understanding the process and the timeline for receiving blood test results can help alleviate some uncertainties associated with the situation. In this article, we will provide you with clear knowledge of what a blood draw chemical test entails, the circumstances in which it is conducted, and when you can expect to receive the test results.

The Blood Draw Chemical Test: 

A blood draw chemical test is performed to measure the concentration of alcohol or drugs in a person's bloodstream. During a DUI arrest, law enforcement may request a blood test to determine if the individual's BAC exceeds the legal limit of 0.08% in California. Unlike breathalyzer tests, blood tests can also detect the presence of drugs in addition to alcohol.

When Blood Draws are Conducted: 

Blood draws are typically conducted in the following situations:

Refusal to Take a Breath Test: If a driver refuses to take a breathalyzer test (breath test) during a DUI stop, law enforcement may request a blood draw as an alternative method to determine BAC.

Accident with Injuries: In cases of accidents involving injuries, law enforcement may order a blood test to assess whether alcohol or drugs contributed to the accident.

Suspected Drug Impairment: Blood tests are used to detect the presence of drugs, including prescription medications and illicit substances, which might impair a driver's ability to operate a vehicle safely.

Repeat Offenders: Repeat DUI offenders or those involved in severe accidents may be subject to mandatory blood testing.

Timeline for Receiving Blood Test Results: 

After a blood draw, the timeline for receiving the test results can vary:

Processing Time: Blood samples need to be sent to a laboratory for analysis. The processing time can range from a few days to several weeks, depending on the workload of the laboratory and the jurisdiction.

Mail or Court Date: In some cases, the arresting agency may send the blood test results to the individual via mail. Alternatively, the results may be provided during the individual's court appearance.

Legal Representation: If you have legal representation, your attorney may receive a copy of the blood test results. This allows them to analyze the results and build an effective defense strategy if necessary.

It's important to note that the timeline for receiving blood test results can be influenced by various factors, including the specific laboratory's workload, administrative processes, and the complexity of the case.


Being subjected to a blood draw chemical test during a DUI arrest can be a nerve-wracking experience. Understanding the purpose of the test, the circumstances in which it is conducted, and the timeline for receiving the results can provide individuals with a clearer perspective on what to expect. While waiting for the blood test results, it's advisable to consult with an experienced DUI attorney who can help you navigate the legal process, analyze the results, and build a strong defense if necessary. Remember that legal procedures vary, and having knowledgeable guidance can make a significant difference in the outcome of your case.
