Local organizations often offer free or low cost testing. While companies do not offer free STI testing, we have chosen our top picks for low cost, convenient kits.

STIs are common. In 2018, the Centers for Disease Control and Prevention (CDC) reported that 1 in 5 people in the United States had an STI. In 2021, data showed that chlamydia, gonorrhea, and syphilis infections continued to increase in the U.S.

This article discusses what home STI testing is, how often a person should test, and where a person can go to find free or low cost STI testing.

Some organizations may offer free or low cost STI tests.

According to Planned Parenthood, health insurance, Medicaid, and other government assistance programs can provide free STI testing. Additionally, some Planned Parenthood centers offer free or low cost testing depending on a person’s income.

Additionally, the CDC’s Get Tested tool provides a database of places that offer free or low cost STI testing, including screens for HIV and hepatitis. People can enter their state, city, or ZIP code to find local centers.

Home STI testing is similar to the testing a person receives in a doctor’s office or healthcare clinic. These tests screen for the presence of infections such as chlamydia and gonorrhea.

To perform a test, a person collects their sample, usually a urine, blood, or swab sample, and then sends it to a lab. Testing at home may be more convenient and private than testing in a clinic, and some companies offer care and advice if a person receives a positive test result.

While there may be some loss of accuracy when taking a home test, if a person follows the instructions on the test kit carefully, home test results are generally reliable. The Food and Drug Administration (FDA) recommends that people call the company if they have any questions about collecting a sample.

Testing for STIs is important to prevent transmitting an infection to sexual partners.

Not all STIs have symptoms. It is important for people to test regularly to ensure that they and their sexual partners receive any treatment necessary to protect their health.

It is also important to test regularly because STIs can cause complications. For example, chlamydia and gonorrhea can cause pelvic inflammatory disease (PID) and lead to infertility.

Pregnant people who have an STI can pass the infection to their infant during delivery. Certain infections can cause premature birth, low birth weight, or lung and kidney infections. Some STIs also increase the chance of miscarriage.

Everyone should receive testing if they believe they are at risk of contracting an STI or showing symptoms of an STI.


Symptoms may include an unusual color, odorous discharge, or urinating pain. However, people can have STIs without having symptoms.

People should receive testing if a sexual partner discloses that they have an infection. STI testing is more accurate after the infection is in the detection period.

Some populations should receive regular testing to minimize the risk of complications. We outline these groups in greater detail below.

While each company may have slightly different instructions, home STI tests generally require:

  • collecting samples, which may involve a finger prick blood test, genital swab, or urine collection
  • placing the samples in a prepaid envelope and sending them off to a lab
  • waiting several days for the test results

Companies will provide detailed instructions on how to collect a sample correctly. If a person finds it difficult to perform a finger prick test, they may wish to ask a friend or family member for help.

Some companies will also offer follow-up care and advice if a person receives a positive test result.

Types of results

Usually, home tests will return one of the following results:

  • Positive or detected: This means the lab has detected the presence of an STI in a person’s sample.
  • Negative or not detected: This means the test has not detected the presence of an STI.
  • Indeterminate: This may mean a person has not collected a sample correctly. People should contact the company for more advice if they receive this result.

How long do results take?

The time it takes a company to return results depends on the type of test a person takes and the company that offers it.

However, people can typically expect home STI test results around a week after the lab receives their samples.

Are at-home STI tests as accurate as testing at the doctor’s office?

The FDA states that home tests are reliable. However, there is room for error if someone collects a sample at home.

If a person believes their test result is incorrect, they may wish to contact a healthcare professional for another test.

What are the signs of an STI?

Some STIs do not have any symptoms. However, if a person experiences any of the following symptoms, they should receive testing:

  • unusual discharge from the penis or vagina
  • bumps or sores around the genitals, buttocks, and thighs
  • inflammation, swelling, pain, or itching around the genitals

At-home STI testing is a convenient and private way to screen for these infections. Several companies offer lower-cost STI testing online.

People can also use local resources to find free or low cost testing. Planned Parenthood, local community centers, and student centers may offer subsidized testing for lower-income people.
