Blood Test For STDs

This blood test comprehensively screens for a range of sexually transmitted diseases (STDs) that can be detected in the bloodstream.

Specifically, it tests for HIV (Human Immunodeficiency Virus), which can lead to AIDS if untreated. Additionally, it checks for Hepatitis B and Hepatitis C, both of which are viral infections that affect the liver and can cause serious liver damage over time.

Finally, the test also screens for Syphilis, a bacterial infection that can cause serious long-term complications if not properly treated.

Why Getting Tested Matters

Engaging in unprotected sexual contact increases the risk of contracting sexually transmitted diseases (STDs), particularly those transmitted through blood. Many of these infections often do not exhibit symptoms, making it difficult to know your sexual health status without testing.

Undergoing STD testing is a quick and straightforward process that provides peace of mind, as most blood-transmitted diseases can be effectively managed or even treated if detected early.

STD Blood Test Screening Explained

Our STD Blood Test Screening package specifically targets the four primary sexually transmitted infections detectable through blood tests, namely HIV, Hepatitis B, Hepatitis C, and Syphilis.

These blood-transmitted infections can spread rapidly, often without any symptoms, and can lead to serious long-term health issues, including liver damage and other complications.

If you have had unprotected sex or are starting a new relationship, it is strongly recommended to get a STD Blood Test Screening done.

Curable And Manageable Blood-Transmitted STDs

Curable blood-transmitted STDs include syphilis (treatment: antibiotics, typically penicillin).

Manageable blood-transmitted STDs include HIV/AIDS (treatment: antiretroviral therapy (ART) to manage and control the virus), Hepatitis B (treatment: antiviral medications; a vaccine is available for prevention), Hepatitis C (treatment: antiviral medications, such as direct-acting antivirals), and herpes simplex virus (treatment: antiviral medications, such as acyclovir or valacyclovir, to manage outbreaks and reduce transmission).

Why Get An STD Blood Test Screening?

Many STDs can remain asymptomatic for long periods; therefore, early detection through blood screening is vital as it enables timely treatment, reduces the risk of long-term health issues, and prevents the spread of these infections.

Regular blood-related STD screenings are a key part of sexual health and well-being, especially for individuals with multiple sexual partners or those in high-risk groups.

Those Needing Testing

Anyone who has engaged in activities that could potentially transmit sexually transmitted diseases through blood should consider getting tested. This includes:

  • People Who Inject Drugs: Sharing needles or equipment for injecting drugs can transmit STDs such as HIV or Hepatitis B and C.
  • People Who Have Had Unprotected Sex: If you have had unprotected vaginal, anal, or oral sex with a partner whose STD status you are unsure of, it is a good idea to get tested.
  • Healthcare Workers: Those who are exposed to blood through their work (like needlestick injuries) should also consider regular testing.

Preventing Blood-Transmittable STDs

  • Practice Safe Sex: Using condoms during sexual activity can significantly reduce the risk of STD transmission, including those that can be transmitted through blood.
  • Regular Testing: Individuals who are sexually active should undergo regular STD testing, especially if they have multiple sexual partners or engage in high-risk behaviours.
  • Know Your Partner’s Status: Communicating with sexual partners about STDs and ensuring they have been tested can help prevent transmission.
  • Avoid Sharing Needles: Injecting drugs or sharing needles can greatly increase the risk of transmitting blood-borne infections like HIV and Hepatitis B and C.
  • Screening Pregnant Women: Screening pregnant women for STDs such as HIV, Syphilis, and Hepatitis B is crucial for preventing transmission to the baby during pregnancy, childbirth, or breastfeeding.
  • Healthcare Setting Safety: Healthcare facilities must adhere to strict infection control practices, including proper sterilisation of medical equipment and handling of blood and bodily fluids to prevent accidental transmission of blood-borne STDs.

Test Results Are In: Your Action Plan

Our London-based doctors are available to offer expert guidance on your test results. If you test positive for HIV, Hepatitis B, Hepatitis C, or Syphilis, it is essential to take the following steps promptly:

  • Contact a healthcare provider experienced in managing HIV, Hepatitis B and C, or Syphilis.
  • Counseling is crucial for understanding your diagnosis, managing emotions, and learning about treatment options.
  • In the case of HIV, a confirmatory test is usually required to ensure accuracy of the initial result.
  • For Hepatitis B, Hepatitis C, and Syphilis, additional tests may be needed to assess the stage of the infection and determine appropriate treatment.
  • HIV treatment involves antiretroviral therapy (ART), which aims to control the virus and maintain immune function.
  • Hepatitis B and C treatments also involve antiviral medications, and the choice of treatment depends on the severity of the infection and liver health.
  • Syphilis is treated with antibiotics, usually penicillin.
  • Regular monitoring of your health is essential to track the progress of the infection and the effectiveness of treatment.
  • Inform your sexual partners and anyone you may have shared needles or bodily fluids with so they can get tested and take appropriate precautions.
  • Practise safe sex going forward.

I would like to have an STI screen but I am uncomfortable talking about my sex life. What should I do?
Our team is highly experienced in these matters, and our confidentiality and discretion is faultless. The doctor will not judge you for anything you share, and the more open and honest you can be, the better we will be able to take care of you. If you are really unable to share details, however, a blood test or bacterial swab will still be able to give you accurate results.
What kind of STI test should I have?
If you have never been tested before, but have been sexually active, or if it has been some time since your last test, the full screening is advisable. Depending on other risk factors, the bacterial test may suffice. If you are in a high-risk group for a certain disease, or are sharing intravenous needles, a blood test may be recommended. All of our test packages include a consultation, so the doctor can advise you about any further tests that might be relevant. Give us a call to discuss your options, our team will be able to advise you.
What are the risk factors for contracting blood-borne STIs?
Anyone can contract any STI, but the risk factors for contracting hepatitis, syphilis, and HIV include being a man who has sex with other men, intravenous drug users, and having an existing STI. Unprotected anal sex is the highest-risk sexual activity for contracting HIV.
