Services We Provide

Drug Testing

As one of California’s premier service providers, DNA & Drug Screening Services offers drug testing panels ranging from the three most commonly abused drugs to panels that include all testable drugs of abuse, including the latest drug trends such as “bath salts” and synthetic “spice / k2” marijuana.

drug test looks for the presence of one or more illegal or prescription drugs in your urine, blood, saliva, hair, or sweat.

Our partnership drug testing laboratories are the industry’s best, each certified or accredited by our industry’s most prestigious regulatory bodies.

Alcohol Testing

The main purpose of an EtG test is to document​ alcohol abstinence. An EtG test can be used to detect the presence in the urine of ethyl glucuronide, a breakdown product of ethanol, which is the intoxicating agent in alcohol.

In General alcohol stays in your system for between one and three hours. By using a urine test and breathalyzers we can detect any alcohol use for up to 24 hours. Hair tests can determine if you drank alcohol in the past 90 days.

We can also screen for EtG in your blood, hair, and nails, but the urine test is the most method.

DNA / Paternity Testing

We proudly offer DNA Testing for both legal reasons and peace of mind.

A DNA paternity test can definitively determine the biological father of a child.

DNA paternity testing compares a child’s DNA pattern with that of the assumed father to determine if there is a match. Testing by an experienced, accredited laboratory, is the most definitive proof of a biological relationship.

If you need paternity test results to be used as a legal document, a DNA Test must be performed.

A business with a drug-free workplace is less likely to have drug-related incidents such as accidents, tardiness, missed days of work, decreased productivity, fines, and lawsuits.

Even one drug-affected employee could cause a huge liability, or hurt other employees and the public, or destroy a business’ brand.

A primary purpose for our existence is to help ensure safety in the workplace by making sure businesses are free of substance abuse.
