FAQs on STD Testing:

Sexually transmitted diseases or STDs, also known as sexually transmitted infections (STIs) or venereal diseases (VD), are infections that passes due to anal, oral and vaginal sex. Generally, STIs do not show any symptoms at the initial stage and hence, it is necessary to perform screening regularly.
There are various options available for patients wishing to screen for STDs. Our packages offer the best combination of value and comprehensiveness – with options to screen for the most prevalent infections through to the full range of complete STD screening as well as specific testing for individual infections if you have any suspicions.
Our standard blood tests for HIV, Syphilis and Hepatitis have a turnaround time of 24 hours, and urine cultures for Chlamydia, Gonorrhoea, Mycoplasma, Trichomoniasis, Ureaplasma, Gardenerella and Herpes I & II takes between 2 and 4 days to get accurate results.

We also offer an expedited service with results within 4 hours for HIV, Syphilis, Hepatitis, Chlamydia and Gonorrhoea. Please note these tests incur an additional fee.
Sometimes you can have an STD without showing any signs or symptoms. If left untreated or undetected the consequences may be severe. As such, it is recommended to undergo regular screening if you are sexually active. It is rare for bacterial infections to resolve themselves, but they can be cured if treated promptly. Other such as Herpes and HIV are not curable but their symptoms can be managed with appropriate medication.
Yes, you can catch herpes by kissing someone on the mouth. There is also a very small risk of catching HIV by kissing someone who has a sore or cut in the mouth whilst you also have an open sore or cut in the mouth.
You need to get tested to know if you have any sexually transmitted disease. Many STDs do not show obvious symptoms. If you remain sexually active, then this includes anal and/or oral sex as well as vaginal intercourse. When the doctors ask this question, they want to know if you have had sex since your last check up that might expose you to an STD or pregnancy. STD tests are an important part of your routine check-up. Thus, if you have any serious concerns about an STD, it is advised to visit a doctor and get tested immediately.
Many STDs don’t have any symptoms or show signs that are extremely mild to notice. However, if you have any of these symptoms, it is advised to consult with your doctor as you may have an STD.
  • None
  • Discharge or abnormal fluid that may be yellow or white from the penis or vagina.
  • Unexplained rash
  • Burning sensation at the time of urination.
  • Sores, blisters, bumps or warts in your genital area along with inner and outer lips, clitoris and vagina for women. However, in case of men, this includes testicles and penis.
Several things can be done to lessen the chances of getting an STD.
  • Stay faithful – When you have sex with one person whom you trust. Having intercourse with someone who is not infected means you will not get an STD from them and they too won’t get it from you.
  • Use condoms – Wear polyurethane or latex condoms as they provide proper protection against STDs when used in the right way every time you enjoy sex with your partner.
  • Choose fewer partners – The more people you enjoy sex with, the greater will be your chances of getting an STD. If you have had sex with new partners, it is important to get tested.
  • Do not mix alcohol and drugs with sex. Getting drunk or high may affect your ability to take smart decisions related to sex.
  • It is suggested not to use IV street drugs and never share needles as many STDs get transmitted through blood.
  • Do not have sex as abstinence is the most effective way to prevent an STD.
It actually depends on how you treat yourself as a virgin. STDs may get transmitted due to anal and oral sex, but many people consider if they haven’t had vaginal intercourse, they are still a virgin. Some STDs usually spread through intimate skin-to-skin contact though there is not any kind of penetration.
Condoms are not completely effective but when used correctly every time, they can help to stay protected from STDs that spread due to body fluids such as – vaginal secretions or semen. They do not protect you against STDs that get transmitted due to skin-to-skin contact.
It is quite possible to get Herpes through kissing, but the chances are less with most STDs.
Most STDs can be tested with a blood test and urine sample. At STD Check London, our doctors check for the following STDs:
  • Gonorrhoea
  • Chlamydia
  • Syphilis
  • Herpes
  • HIV
  • Mycoplasma Genitalium
  • Hepatitis
There are certain cases when the blood tests are not accurate as other kinds of testing. It might take one month or longer after getting exposed to some STIs for appropriate blood tests. For example, if HIV has been contracted, it may take almost 28 days to fewer months for the tests to detect the infection.
Common way to get negative Gonorrhoea and Chlamydia tests would be by testing often after you had sex or by urinating soon when the test is done with urine. With Gonorrhoea, the results will be accurate just one week after exposure, however, with Chlamydia, most results are accurate just 2 weeks after the exposure.
STDs that occur due to bacteria may be cured by taking antibiotics. Some bacterial STDs consist of –Gonorrhoea, Chlamydia, Mycoplasma Genitalium and Ureaplasma. STDs caused by viruses can be controlled, but not treated. In case you get a viral STD, you will have it always.
It usually requires 3 to 4 days to get the results from either a urine test or a swab for different STDs.
With different health care centres, the costs might differ depending on the area to choose. The prices for different tests usually range between £50 and £1250.
Some STDs such as syphilis, HIV and hepatitis B may lead to some infections in your body. Sometimes, you may get an STD without any signs or symptoms. However, at other times, the symptoms might go away by themselves. Though you cannot treat some STDs, most of them can be treated when detected on time.
Some signs are irregular discharge from the penis, anus or vagina during urination, skin growths or lumps around the genitals or anus.
If you are having sexually transmitted infection or STI, it is advised to visit your nearest sexual health clinic in London. It is usually possible to treat STIs successfully, but you need to check the symptoms at an early stage.
A genitourinary medicine or GUM clinic is where you need to attend a session between the doctor and the patient. These are usually located at the health care centre or hospital that offers different sexual health services such as – contraception and contraception advice, testing as well as treating sexually transmitted infections. Certain STI include – chlamydia, syphilis, genital warts, gonorrhea and counselling for HIV and AIDS.
Sexual health clinics usually provide different services such as treating and testing different sexually transmitted infections or STIs.
Performing necessary tests and treating sexually transmitted infections is confidential and most infections can be cured. A genitourinary medicine (GUM) clinic has some specialists who have done specialisation in sexual health. They help in conducting tests and treatments for different STIs.
Yes, it is quite possible to get an STD from receiving oral sex without using a condom. Herpes may spread easily from one partner to other at the time of oral sex as it gets transmitted through skin-to-skin contact and not fluids only. Others such as chlaymdia and gonorrhoea may cause infection to the throat.
Bacterial STDs may get treated by taking antibiotics when the treatment starts early. Though you cannot treat viral STDs, you will be able to manage its symptoms with proper medications. There is a vaccine available against hepatitis B, however, it will not be of much help if you are suffering from this disease.
STDs usually get transmitted through direct contact with infected body fluids such as – blood, semen or vaginal fluids. They may spread by contact with infected skin, mucous membranes and mouth sores. You might get exposed to infected body fluids and skin through oral, anal or vaginal sex.
STD symptoms may range from mild to severe. Many women suspects an STD infection when there is an abnormal symptom in the genital region, such as rash, discharge, itching, pelvic or vaginal pain. The only way to know if you have an STD is to get tested on time.
