A person can order a home syphilis test online or buy one from some in-store pharmacies.

Usually, a person needs to take a blood sample from a finger prick. And more thorough tests, which can identify various STIs, may also need urine or swab samples.

A pharmacist or another healthcare professional may be able to recommend tests that are reliable and accurate.

Traditional tests, in which a healthcare professional collects a sample and sends it for testing, are always more accurate than home tests. In part, this is because people unused to collecting samples may do it incorrectly.

One 2015 systematic review compared the accuracy of self-collected and clinician-collected samples for STI testing. It found that the samples collected by clinicians were more reliable, though these could still yield inaccurate results.

It is worth noting from the outset that no home tests for syphilis have approval from the Food and Drug Administration (FDA).

A person may opt for this type of testing due to:

  • Convenience. A person can test on their own schedule from the comfort of home.
  • No unexpected medical bills. For most of these tests, a person pays the whole amount up front.
  • Some tests are panels. This means that the lab tests one sample for several STIs.

However, a person may not want to provide a blood sample with a finger prick, possibly due to a fear of needles or a discomfort about the sight of blood.

Anyone interested in a home test should make sure the company provides access to a healthcare professional who can discuss the results and advise about the next steps.

The costs vary by brand and whether the test checks for single or multiple infections. Tests in this list that just check for syphilis cost $29–78. The panel tests are more expensive.

Some companies allow HSA and FSA payments, and some insurance companies may reimburse customers for the cost. It is worth researching payment options before making a purchase.

The Centers for Disease Control and Prevention (CDC) recommend regular testing for:

  • pregnant people
  • men who have sex with men
  • people with HIV
  • people with partners who have tested positive for syphilis

As Planned Parenthood notes, many people with STIs have no symptoms. The organization recommends that anyone who has had vaginal, anal, or oral sex consider getting tested, particularly if there was no barrier method, such as a condom.

A person may prefer to have an STI test at a clinic or a doctor’s office. If a person has used an at-home test, they should contact a doctor if the result was positive.

An individual should also contact a doctor if they have any symptoms that may indicate syphilis, regardless of the result of the test. Another STI or health condition may be causing the symptoms.

Many people with syphilis do not have immediate symptoms. There may be painless sores on the genitals, mouth, anus, or rectum and enlarged lymph nodes around the sores.

Some later symptoms may include:
