At-Home STD Testing

Testing for STDs at home is safe, convenient, and private. Performed regularly, it can help you stay healthy and avoid unknowingly transmitting STDs.

You have many options for at-home STD testing. The best at-home STD tests are FDA approved and evaluated for safety and accuracy with fast result turnaround times and support from health care professionals.

At-home STD testing kits should include instructions for collection and test registration, along with materials such as containers and swabs to collect and send your sample to the lab. Most at-home STD tests offer results in about five days through a secure online patient portal.

Modesto is located in Stanislaus County, not far from the San Francisco Bay area. Between 2014 and 2018, the county saw significant increases in chlamydia and syphilis infections, according to the California Department of Public Health’s (CDPH) most recent STD report. Gonorrhea infections also rose slightly.


With nearly 2,920 new infections recorded in 2018, chlamydia is the most common STD in Stanislaus County. This represents an infection rate nearly 27% higher than the incidence seen in 2014. A similar increase occurred in California as a whole during that time frame, according to CDPH data.

Female residents accounted for more than two-thirds of Stanislaus County’s chlamydia infections in 2018. County-level age data is not available, but statewide, nearly four in five female cases were in the 15 to 29 age group.


Gonorrhea is the second-most commonly reported STD in Stanislaus County, and in 2018, the CDPH recorded nearly 830 new infections. This incidence was only 3% higher than in 2014, but statewide, diagnoses soared by 72% over the same period.

In 2018, about 55% of the county’s gonorrhea diagnoses were in men. Across California, men aged 25 to 29 had the highest infection rate, followed by those in the 30-34aged group. Among women, gonorrhea was diagnosed most often in 20- to 24-year olds.


Cases of syphilis — the county’s third-most common STD — are also on the rise. From 2014 to 2018, reported primary and secondary syphilis infections soared by more than 113%. As of 2018, the county had the ninth-highest infection rate of California’s counties.

The county’s female residents are diagnosed with syphilis at a much higher rate than the state average. While rates of congenital syphilis have risen statewide, Stanislaus County has been especially hard hit. From 2014 to 2018, the incidence rate increased by more than 1,100%. To protect infants from this infection, the CDC recommends routine syphilis screening for pregnant women.

People who have an STD often don’t have any symptoms. However, they can still spread the infection to their partners, and pregnant women may pass the infection to their infants. Undetected STD infections may cause serious health complications in the long term. If you’re sexually active, take control of your health by visiting one of the Modesto-area’s many STD testing clinics or using an at-home STD test.
