Sexually transmitted diseases (STDs) are passed on during sexual vaginal and anal intercourse and oral sex. STDs sometimes cause symptoms, but the majority of cases involve no symptoms whatsoever. Being symptom-free usually results in the infection being spread to other people. Therefore, there is always a risk that the person you have sex with has an STD without knowing it. The best way to take care of your sexual health is to ensure appropriate protection and to have tests done. You should keep in mind that you might also have an infection and spread it without knowing.

Be protected

Using condoms during intercourse is an effective way of protecting yourself against STDs. Condoms can also be used during oral sex. A woman receiving oral sex can use a split condom or an oral sex barrier (a dam) for protection. For men, condoms protect against STDs but are also the only way to make sure you are using reliable contraception.

Testing for STDs 

STDs such as chlamydia and gonorrhoea can be tested from a urine sample. The diseases that can be tested using a blood sample include HIV, syphilis, hepatitis B and hepatitis C. There is no simple test for some STDs such as herpes and genital warts. However, fluid taken from herpes blisters can be used to detect HSV using specific virus tests, and genital warts are usually diagnosed on the basis of their typical appearance.

All STDs may be asymptomatic in the beginning. You should get tested if you have the slightest suspicion you are infected. You should also get tested if you have had unprotected sex with anyone who isn’t your long-term partner.

  1. If you do not have any symptoms but want certainty, free of charge remote testing is the easiest solution. A free remote testing kit gives you quick results if you suspect a gonorrhoea or chlamydia infection. To order the remote testing kit, use the link on the right-hand side of this page. Please note, that remote testing is not possible for infections based on mucous membranes of the mouth or rectum. If you suspect an infection of the mouth or rectum, please contact a healthcare professional for advice.
  2. If you have any symptoms or need more extensive testing for some reason, please contact a healthcare professional who will assess if you need further treatment. Symptoms may include burning when urinating or difficulty in passing urine, abnormal discharge from the urethra or vagina, itching, stinging, bumps, blisters or ulcers around the genitalia, lower abdominal pain and fever. However, an STD infection can’t be diagnosed based on symptoms only; the diagnosis must always be based on laboratory tests. Please mention if you have engaged in unprotected oral or anal sex, so that all necessary tests can be conducted.


Treatment is always decided based on the disease diagnosed.
