What is the U-Test Syphilis Rapid Home Test Kit?

It is a fast and easy-to-use home testing kit designed to detect the presence of syphilis antibodies, supporting timely awareness and action. Syphilis is a bacterial sexually transmitted infection that can go unnoticed without testing, and rates in the UK have risen steadily over recent years. This kit offers a convenient way to check for syphilis from home, without the need for a clinic appointment or a laboratory visit.

How does the test work?

The test works by detecting antibodies to Treponema pallidum, the bacterium responsible for syphilis, using a small blood sample obtained via a finger-prick. The sample is applied to the test cassette with the buffer solution supplied and travels across a strip carrying the matching antigen. If antibodies are present, an indicator line appears. A separate control line confirms that the test has run correctly.

What do the results mean?

Two lines means antibodies have been detected. Your instruction leaflet may call this a reactive result, which is the laboratory term for a positive one. One line on its own means no antibodies were detected, which the leaflet may call non-reactive, meaning negative. Either way, the result is a screening result and not a diagnosis.

Who is this test kit for?

The kit is intended for use by adults aged 18 years and over, men and women. It suits anyone seeking a discreet at-home syphilis screening option, whether you are testing as part of a routine sexual health check, following a potential exposure, or because a partner has been diagnosed.

When should you use it?

Antibodies take time to develop after infection. A test taken in the first few weeks after exposure can be negative while infection is developing, and UK sexual health guidance is that syphilis is not considered excluded until testing at twelve weeks after the exposure you are concerned about. If your result is negative and the exposure was recent, arrange repeat testing through a sexual health clinic rather than treating the result as final.

How accurate is this test?

Rapid tests of this kind detect fewer infections than the laboratory testing used by the NHS and by sexual health clinics, which examines the sample in far greater detail. A negative result lowers the likelihood that you have syphilis, but it does not rule it out. A positive result is a reason to seek care rather than a diagnosis, and always needs confirming by a clinician.

This kit is a convenient first check, not a replacement for testing in person. If you have symptoms, a partner has been diagnosed, or you are at all unsure about your result, arrange testing at a sexual health clinic or through your GP. NHS sexual health services are free and confidential and you do not need a referral.

What should you do with your result?

If your result is positive, consult a healthcare professional or sexual health clinic promptly for confirmatory blood testing and treatment. Syphilis is very treatable, particularly when it is caught early. Avoid sexual contact until you have been assessed, and let recent partners know so that they can be tested as well.

How to use the U-Test Syphilis Rapid Home Test Kit

Read the enclosed instructions carefully before starting. Wash your hands thoroughly and lay out all components on a clean, flat surface.

• Before you start: Use warm water when washing your hands, which makes the sample easier to collect, and allow the kit to reach room temperature.
• Check the kit: Confirm the expiry date and check that the foil pouch is undamaged.
• Take the sample: Use the lancet provided to obtain a small blood sample from your fingertip. Allow a drop to form rather than squeezing the finger hard.
• Apply the sample: Draw the blood up with the pipette supplied and apply it to the designated area on the test device.
• Add the buffer: Add the buffer solution as directed and start a timer.
• Read the result: Wait 10 to 15 minutes before reading your result. Do not read results after 20 minutes.
• Interpreting the lines: Two lines means antibodies have been detected, which is a positive result – your leaflet may call this reactive. One line on its own means none were detected, a negative or non-reactive result. No lines at all means the test is invalid and should be repeated with a new kit.
• Afterwards: Apply light pressure to the fingertip until any bleeding stops.

If your result is positive

Consult a healthcare professional or sexual health clinic promptly for confirmatory blood testing and treatment. Treatment should not be started on the basis of a home test alone. Avoid sexual contact until you have been assessed, and let recent partners know so that they can be tested.

If your result is negative but you are concerned

A negative result does not completely rule out infection, particularly if you tested during the early stages after exposure. Arrange repeat testing through a sexual health clinic if you remain concerned.

If no lines appear

The result is invalid and cannot be interpreted. Repeat the test using a new kit.

Testing in person is the more thorough option

A home test is a convenient first step rather than a replacement for a full sexual health check. Testing at a sexual health clinic or through your GP uses laboratory blood tests that can tell a current infection from a past treated one, and can screen for other infections at the same time. NHS sexual health services are free and confidential and you do not need a referral. If you have symptoms, a known exposure, or any doubt about your result, we would recommend arranging in-person testing.

There are no side effects from using the U-Test Syphilis Rapid Home Test Kit in the way a medicine has side effects. It contains no medicinal ingredients and nothing is taken into the body.

What you may experience

• The finger-prick: The fingertip may feel briefly sore and can bruise slightly. This settles within a day or two.
• Bleeding: Light bleeding from the puncture site is normal and stops with gentle pressure.
• Waiting for the result: Some people find the wait stressful. The result appears within 10 to 15 minutes.

If your result is positive

Contact a healthcare professional for confirmation and appropriate treatment. Syphilis responds well to antibiotic treatment, particularly when caught early.

Contact your GP or a sexual health clinic promptly if you develop any of the following

• A painless sore on the genitals, anus or mouth: This is a recognised early sign of syphilis and it heals on its own, which does not mean the infection has cleared.
• A rash on the palms of the hands or soles of the feet: This should be assessed promptly.
• Swollen glands, fever or patchy hair loss after a possible exposure: Seek advice from your GP or a sexual health clinic.
• Any change in vision or hearing, or a severe headache: Seek medical advice urgently.

This test is for self-testing purposes only and does not replace professional medical diagnosis or advice. Follow all instructions exactly to avoid false results.

Before you use the kit

• Confirming a positive result: A positive result should be confirmed by a healthcare professional or sexual health clinic with laboratory blood testing before any treatment is started.
• A negative result: Rapid tests of this kind detect fewer infections than laboratory testing, and antibodies can take up to twelve weeks to appear. A negative result does not exclude infection, particularly if the exposure was recent.
• Previous treatment: If you have been treated for syphilis before, antibodies can remain detectable afterwards. Discuss any positive result with a healthcare professional, who can interpret it alongside your history.
• Other infections: The kit tests only for syphilis. If you are concerned about other sexually transmitted infections, arrange a full screen through a sexual health clinic or your GP.
• Bleeding risk: If you take anticoagulant medication or have a bleeding disorder, speak to a pharmacist or your GP before using a finger-prick test.
• Single use: Do not reuse the test or the lancet, and do not use the kit after the expiry date printed on the packaging.
• Pregnancy: If you are pregnant, speak to your midwife or GP rather than relying on a home test.

Storage and disposal

• Where to keep it: Store the kit in a cool, dry place away from direct sunlight, and out of reach of children.
• Keep the pouch sealed: Leave the cassette in its foil pouch until you are ready to test.
• The used lancet: Place it in a rigid sealed container before putting it in your household waste, so that it cannot injure anyone.
• Everything else: Dispose of the remaining components in your household waste, sealed in a plastic bag.
• Do not flush: No part of the kit should be flushed down the toilet.
