SMITH, J.

The Department of Motor Vehicles (DMV) suspended Jose Najera’s driver’s license after it found he violated Vehicle Code section 13353.2 1 by driving with a blood-alcohol concentration (BAC) of 0.08 percent or more. The suspension was upheld after an administrative hearing. The superior court, however, granted Najera’s petition for a writ of mandate, overturning the suspension. The court found that Najera’s expert had successfully challenged the scientific validity of the blood test results on which the finding of a violation was based. The DMV now argues that the court erred. We affirm.

FACTS AND PROCEDURAL HISTORY

On November 25, 2012, the Bakersfield Police Department received a call reporting a single-vehicle motorcycle accident. The caller said the driver thought he broke his nose, but did not want the police to be called because he had been drinking.

*176 An officer arrived at the scene at 7:35 p.m. According to the police report, Najera, the motorcycle driver, said he was driving around 40 miles per hour when another driver came up beside him and yelled at him. This caused Najera to lose control, collide with the curb, and fall.

The officer smelled alcohol on Najera’s breath and noticed that Najera’s speech was slurred. Najera had a prior DUI conviction within the previous 10 years.

A second officer conducted a DUI evaluation. Najera denied that he had been drinking and refused to take a breath test. He was arrested and taken to a hospital for injuries he sustained in the accident. At 9:05 p.m., he submitted to a blood draw for alcohol testing.

A DMV form ordering suspension of Najera’s driver’s license was served on him by the arresting officer on the night of the arrest. The form stated that if the laboratory results showed Najera did not have a BAC of 0.08 percent or more, the suspension would be set aside. It also informed him of his right to an administrative hearing.

The blood sample was tested and found to have a BAC of 0.19 percent, more than double the limit established by section 13353.2, subdivision (a)(1). Najera requested a hearing, which, after several continuances, took place on April 17 and August 7, 2013.

At the hearing, the DMV submitted a sworn statement by the arresting officer, the police reports, the blood test report, and Najera’s driving record. A phlebotomist testified that she did not specifically remember drawing Najera’s blood. She described the procedures used for drawing blood and submitting samples to the police.

Najera presented expert testimony attacking the manner in which the blood test was conducted and the way the results were reported by the Kern County Regional Crime Lab. Najera’s expert, Janine Arvizu, made two main points.

The first point was that Najera’s blood sample was smaller than it should have been. Arvizu explained that the tube used to take the blood sample contained an anticoagulant and a preservative in a vacuum. The vacuum was sufficient to draw 10 milliliters of blood into the tube. This quantity (plus or minus 0.7 milliliters) of blood would ensure that the quantities of the anticoagulant and preservative would be correct. According to materials published by the tube’s manufacturer, Becton Dickinson, smaller samples can lead to “poor product performance or inaccurate results.” Further, a low sample volume can indicate insufficient vacuum in the tube, which in turn can *177 indicate that the tube’s seal has leaked. If a tube leaks, contaminants can enter from the atmosphere, including microbes that can cause fermentation. Fermentation would increase the alcohol level in the sample, invalidating the test results. For these reasons, according to Arvizu, a test on a sample smaller than that called for by the manufacturer would be inherently unreliable.

Arvizu testified that data from the Kern County Regional Crime Lab showed a pattern of low sample sizes for blood draws taken for alcohol analysis. She compared lists of samples from that lab, which is in Bakersfield, with lists from labs in other jurisdictions, and found that, while most of the samples tested in Bakersfield were smaller than the size mandated by the manufacturer of the tubes, most of those tested in other labs were adequate. Arvizu also compared the manufacturer’s lot numbers for the tubes used in Bakersfield and those used elsewhere. The pattern of undersized samples in Bakersfield and adequate samples elsewhere held, even when consideration was restricted to tubes from the same lot.

Arvizu testified that the pattern could be explained by a failure at the Bakersfield lab to store the tubes at a proper temperature. The manufacturer’s instructions stated that the tube should be maintained at a temperature between 39 and 77 degrees Fahrenheit. A lower or higher temperature could affect the tubes’ seals and cause vacuum leakage. Arvizu described this as a common problem.

Najera’s sample was only six milliliters. Arvizu opined that the small sample meant the test results were not scientifically valid.

Arvizu’s second main point was that the Kern County Regional Crime Lab failed to report data generated by the testing apparatus that could have confirmed or disconfirmed the reported BAC of 0.19 percent. The lab used a technique called gas chromatography, which employs a device called a gas chromatograph. The device is a heated box, inside of which are two narrow coiled columns, each about 30 meters long. The inside of each column is treated with chemical compounds chosen for their ability to interact with substances that might be in the sample being tested. The sample passes through the two columns, and detectors at the columns’ exit points are used to determine whether the sample contains alcohol.

The inner surfaces of the two columns are treated with different chemical preparations. This allows the sample to be tested in accordance with two different chemical principles, which in turn allows the results from the second column to confirm or disconfirm the results from the first. With positive data from only one column, a sample can only tentatively be said to contain alcohol. The data from the second column are necessary to confirm the *178 presence and the concentration of alcohol. Arvizu said, “[I]t’s a general matter of scientific principle that the detection and the identification of a compound by gas chromatography requires confirmation by a second technique based on a different chemical principle in order to be scientifically valid.” The American Academy of Forensic Sciences “specifically says that second column confirmation is needed for ethanol,” Arvizu testified. Data from a single column can suffice “as a screening test,” but “that second technique [using the second column] must be done in order to scientifically conclude that it is ethanol and only ethanol” contributing to the indication that the 0.08 percent BAC threshold had been reached or exceeded.

According to Arvizu, the Kern County lab used a dual-column gas chromatograph with two columns installed.
