In New Zealand, like in many places, the number of syphilis cases has been rising. This serious but treatable bacterial infection, which is a sexually transmitted infection (STI), often goes unnoticed in its early stages. This makes regular testing important for public health. If you are sexually active, knowing the signs and your testing options is a key part of self-care and protecting your partners.

This guide from TestMyHealth explains the stages of syphilis, walks you through the testing process in New Zealand, and helps you get instant answers with a discreet at-home solution.
Understanding Syphilis Symptoms: The Stages of Infection
Syphilis is caused by the bacterium Treponema pallidum and goes through several distinct stages. Up to 50% of people may not have noticeable symptoms, which is why testing is crucial. For those who do experience symptoms, they can vary significantly by stage.
1. Primary Syphilis: The Silent Sore
The first sign is the chancre—a small, firm, and usually painless sore that appears at the entry site of the bacteria.
When it appears: It typically shows up 3-4 weeks after infection, but it can take 10 to 90 days.
Key Feature: The sore is typically not painful, itchy, or noticeable. This is why it’s easily missed, especially if it is inside the vagina, cervix, or rectum.
Duration: The chancre heals on its own within a few weeks, but the infection remains active and contagious. Even after the sore is gone, the infection is still in your body.
2. Secondary Syphilis: The Whole-Body Rash
This stage usually starts as the chancre heals or a few weeks after it disappears. The bacteria have spread throughout the body, leading to more widespread symptoms.
Key Symptom: A rash that doesn’t itch can appear on any part of the body. It often shows up on the palms of the hands and the soles of the feet, which is a classic sign.
Other Symptoms: Flu-like symptoms are common, including fever, swollen lymph nodes, sore throat, headaches, muscle aches, and fatigue.
3. Latent Syphilis: The Hidden Infection
After the secondary stage, the infection enters a latent stage with no visible signs or symptoms. This stage can last for years.
4. Tertiary Syphilis: The Long-Term Danger
If left untreated, a small percentage of people can advance to this serious stage, which can cause permanent and potentially life-threatening damage to major organs like the brain, heart, eyes, and nervous system.
The Fastest Way to Know: The TestMyHealth Instant Syphilis Home Test Kit
Given how easily syphilis symptoms can be missed, getting a syphilis test is the only reliable way to confirm an infection. For many, visiting a clinic can be inconvenient or anxiety-inducing. This is where the TestMyHealth Syphilis Home Test Kit provides a solution.
Rapid Results. Complete Privacy.
Our kit is designed to give you fast and discreet information:
Instant Result: You get your results in just 10 to 15 minutes in the comfort and privacy of your home.
No Lab Required: The TestMyHealth kit is a rapid antibody test that uses a simple finger-prick blood sample and shows the result directly on the device, similar to a rapid COVID-19 or pregnancy test.
How it Works: The test detects antibodies that your body makes in response to the syphilis bacteria. You simply collect a small blood sample from your fingertip, add it to the testing device, add the buffer solution, and wait 10-15 minutes to read the result.
The Critical Next Step: Screening vs. Diagnosis
It is important to know that the TestMyHealth Syphilis Home Test Kit is a high-quality initial screening tool.
Positive Result: A positive result means syphilis antibodies were detected. This suggests a likely current or past infection. You must immediately contact a healthcare professional or sexual health clinic in New Zealand for laboratory confirmation and treatment.
Negative Result: A negative result is good news, but due to the window period (the time it takes for antibodies to appear, which can be up to three months after exposure), it may not rule out a very recent infection. If you have any symptoms or a recent high-risk exposure, you should still seek professional advice and consider re-testing later.
Professional Testing and Treatment in NZ
While at-home screening with TestMyHealth offers a fast answer, diagnosis and treatment must be done by a medical professional.
Professional Syphilis Testing
In New Zealand, confirmatory testing is done through a laboratory blood test. These tests often follow a two-step process to confirm if the infection is active. They are usually available and can be free or low-cost at:
- Sexual Health Clinics (recommended for confidentiality)
- General Practitioners (GPs)
- Family Planning Clinics
Treatment: Quick and Effective
The good news is that syphilis is completely curable, especially when caught early.
Medication: Syphilis is treated with antibiotics, most commonly with a Penicillin injection. Usually, one dose is enough for early syphilis.
Follow-Up: You will need follow-up blood tests to ensure the infection has been fully treated and that the antibody levels are dropping.
Prevention and Routine Care
Untreated syphilis can lead to serious health complications. If transmitted during pregnancy, it can harm the baby. Regular testing is important not just for yourself, but also for your partners and the wider community in New Zealand.
Make the TestMyHealth Syphilis Home Test Kit part of your routine. It’s the fastest and most convenient way to monitor your sexual health, giving you instant peace of mind and the information needed to seek professional care if necessary.
Frequently Asked Questions (FAQ)
Q1: What are the main syphilis symptoms I should look out for?
A: The main symptoms are a painless sore (chancre), often on the genitals, followed by a non-itchy body rash, commonly on the palms and soles. However, many people don't notice symptoms as they can be mild or hidden, making testing essential.
Q2: How fast is the TestMyHealth Syphilis Home Test Kit?
A: The TestMyHealth Syphilis Home Test Kit gives instant results that you can read visually within 10 to 15 minutes after performing the simple finger-prick test. There are no lab wait times.
Q3: How is a professional syphilis test different from the TestMyHealth kit?
A: The TestMyHealth kit is a rapid screening tool, giving you quick at-home results. A professional syphilis test is a laboratory blood test used for confirmatory diagnosis and to see if the infection is active. If the home kit is positive, you must visit a healthcare provider for the official lab test and treatment.
Q4: Does a negative result from the Syphilis Home Test Kit mean I am 100% clear?
A: A negative result is a strong sign you are clear, but be aware of the "window period." It can take up to three months after exposure for syphilis antibodies to be detected. If you’ve had a recent high-risk encounter, consider re-testing in three months for certainty.
Q5: Is syphilis curable in New Zealand?
A: Yes. Syphilis is fully curable with antibiotics, typically a Penicillin injection, especially when detected early through a syphilis test or a home screening kit like TestMyHealth. Prompt treatment is key to avoid serious long-term health issues.
