Understanding the symptoms of syphilis is crucial for early detection and treatment.

Not everyone with syphilis experiences symptoms, which means it\u2019s easy to pass it on to someone else \u2014 that\u2019s why regular STI testing is so important. Aim to get tested every year, or more often if your situation has changed, such as a relationship status, sexual activity, or sexual partner(s).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While, as mentioned, not everyone experiences symptoms with a syphilis infection, particularly in the early stages.

In this case, a blood test can detect syphilis one to two weeks after the sore appears, so it\u2019s best to get tested four to five weeks after exposure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you don\u2019t have symptoms, it\u2019s recommended to wait 90 days after exposure to get tested or to retest for a more accurate result.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the meantime, whether you have symptoms or not, if you\u2019re feeling anxious about potential exposure, <\/span><a href=\"https:\/\/www.getmaple.ca\/?utm_source=google&amp;utm_medium=cpc&amp;utm_campaign=1655686735&amp;utm_content=63981513299,545382292005&amp;utm_term=getmaple&amp;gad_source=1&amp;gclid=CjwKCAjwreW2BhBhEiwAavLwfI84q9TXLkKdO1T4sThXhZl2yZbFoRTL9F66ZL8YnISl79xTS-aT6RoCk9wQAvD_BwE\"><span style=\"font-weight: 400;\">consider speaking with a healthcare provider<\/span><\/a><span style=\"font-weight: 400;\">.

This is why the Public Health Agency of Canada provides healthcare providers guidance in the next steps. In Canada, the type of test(s) to diagnose syphilis may differ between provinces and territories but may include one or a combination of the following tests:<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Venereal disease research laboratory (VDRL)\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rapid plasma reagin (RPR)\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Trepomenal-specific enzyme imminoassay (EIA)\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fluorescent trepomenal antibody absorption (FTA-ABS)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><i><span style=\"font-weight: 400;\">T. pallidum<\/span><\/i><span style=\"font-weight: 400;\"> particle agglutination (TP-PA)\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Chemiluminescent immunoassay (CIA)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Microhemagglutination assay for <\/span><i><span style=\"font-weight: 400;\">T. pallidum<\/span><\/i><span style=\"font-weight: 400;\">\u00a0 (MHA-TP)<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The<b> non-treponemal tests<\/b>(VDRL and RPR) look for antibodies against cardiolipin, a type of lipid in the bacteria membrane, in the blood or cerebrospinal fluid (CSF). These tests are only positive after the first lesion or chancre develops, peaks in the first year, and then taper down. They can be undetectable in later stages of syphilis and, therefore, are not used to monitor disease progression. This type of test requires a trained lab technician.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><b>Treponemal tests <\/b>(EIA, FTA-ABS, TP-PA, CIA, and MHA-TP) screen for antibodies directly against <\/span><i><span style=\"font-weight: 400;\">T. pallidum.<\/span><\/i><span style=\"font-weight: 400;\"> A positive treponemal test can be detected early, but cannot tell the difference between a new exposure and a previously treated infection.

Direct tests are used less often than serologic testing methods and may not be offered at every laboratory due to the time sensitivity and required technician skill set and reliability of the tests. These types of tests can include darkfield microscopy, immunofluorescent antibody staining, Nucleic Acid Amplification Tests (NAAT), immunohistochemistry, or silver staining. A healthcare provider may conduct a physical examination including a neurologic exam if they suspect latent or tertiary syphilis.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><b>Cerebrospinal fluid (CSF)<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400;\">The cerebrospinal fluid Venereal Disease Research Laboratory (<\/span><a href=\"https:\/\/www.ucsfhealth.org\/medical-tests\/csf-vdrl-test#:~:text=The%20CSF%2DVDRL%20test%20is%20done%20to%20diagnose%20syphilis%20in,(secondary%20or%20latent)%20syphilis.\"><span style=\"font-weight: 400;\">CSF-VDRL test<\/span><\/a><span style=\"font-weight: 400;\">) is performed to diagnose syphilis in its late stage, when the disease may have reached the brain or spinal cord. That\u2019s because untreated syphilis can cause neurosyphilis, an infection in the central nervous system. The CSF-VDRL test (also called a neurosyphilis test) looks for antibodies in CSF to diagnose neurosyphilis \u2014 meaning, syphilis in its late stage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><b>Congenital syphilis<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400;\">Pregnant women with syphilis could pass the disease onto their babies, which can <\/span><a href=\"https:\/\/www.marchofdimes.org\/find-support\/topics\/planning-baby\/congenital-syphilis\"><span style=\"font-weight: 400;\">cause<\/span><\/a><span style=\"font-weight: 400;\"> miscarriage, stillbirth, premature birth, or future health problems for the baby, such as brain or nerve problems, and bone or joint abnormalities, among others.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An assessment for congenital syphilis should be performed at 20 weeks of pregnancy with a detailed obstetrical ultrasound, or in infancy for children presenting signs or symptoms.
