Lymphogranuloma venereum (LGV) testing is not routinely offered in sexual health clinics.
A sample is taken from the rectum and penis, or vagina and cervix. This is first tested for the presence of Chlamydia. You may be advised to have an LGV test if you have tested positive for Chlamydia and you are showing symptoms of an LGV infection.
Polymerase chain reaction (PCR) tests are done to ascertain whether the sample contains genetic material belonging to the LGV bacteria.

In order to be most prepared and leave plenty of time for questions & discussions, we will ask you to fill out a simple questionnaire.
We will begin by assessing your medical & sexual history, any symptoms you may be experiencing and discuss any questions you may have.
If it is still appropriate to proceed with the LGV test (and you would like to), we will take a swab from the appropriate areas.
Medicine is a complicated subject and sometimes these guidelines don’t always hold the answers.
For example, treating an STI in a patient who has developed a resistance to routinely used antibiotics.
Unlike most private clinics, we have medical consultants here to help you navigate through such problems and get you on the right track in no time.
About The Test
How do you test for LGV?
LGV is not routinely tested for in sexual health clincis. LGV tests are considered following a positive Chlamydia test result if the symptoms are the same as those for LGV.
In individuals who are suspected to have a possible LGV infection, a sample is taken from the rectum and penis, or vagina and cervix. This is first tested for the presence of Chlamydia. After this, polymerase chain reaction (PCR) tests are done to ascertain whether the sample contains genetic material belonging to the LGV bacteria.
When should I get tested for LGV?
You should get tested for LGV if:
- You have tested positive for Chlamydia and your symptoms are similar to those of LGV.
- Your sexual partner(s) has tested positive for Chlamydia and LGV, and you have recently had unprotected sex with them.
What is the window period for LGV?
You can start to show symptoms of LGV between 3 to 30 days after the exposure occurs. During this time you will be able to accurately test for LGV.
Will I need a physical examination?
If you are experiencing any pain in the groin or swelling in the inguinal regions, discomfort, pain or itching sensation on urination, a physical examination may be performed.
How can I prepare for my appointment?
Try to remember (as much as possible) the details of why you are visiting. For example, if you are showing symptoms, try to remember when these started and the potential cause of exposure.
Relax, Clarewell Clinics is a safe space. Your medical history with us is completely confidential so you can be as open and honest as you wish to be with us.
Can another infection be mistaken as LGV?
There are several other infections which can also present in a similar manner as LGV. Your clinician will do tests to determine what the right diagnosis is.
Other sexually transmitted infections (STIs) such as syphilis, chancroid, herpes simplex, herpes or granuloma inguinale can also cause symptoms similar to LGV infection and will have to be ruled out.
About The Results
How will I receive my LGV test results?
You can receive your LGV test results by either text or a secure email.
Do I have to take any precautions whilst waiting for my results?
It is recommended that you avoid engaging in sexual intercourse until you have received your results.
If you receive a positive result you will you need to avoid engaging in sexual intercourse until you have finished the full course of your treatment.
What do my LGV test results mean?
LGV tests are only run if you have tested positive for Chlamydia and you are showing symptoms of LGV.
If you have tested positive: you have the LGV infection and you need to start a course of antibiotics straight away.
If you have tested negative: you do not have the LGV infection, you need to start a course of antibiotics for Chlamydia.
What happens if my LGV test is positive?
If your LGV test result is positive, you will be prescribed a course of antibiotics.
Pregnant and breastfeeding women who have tested positive for LGV will be prescribed a different course of antibiotics that are just as effective in clearing up the infection.
Do I have to tell my partner if I test positive for LGV?
Yes. It is recommended to tell your sexual partners that you have tested positive for LGV to avoid passing the infection onto others.
Can I get a certificate of my LGV test results?
Yes, of course. Please request this in your pre-appointment questionnaire and we will share this with you after your appointment.
If you are seeking to get a certificate for official purposes, then we may require your passport or driving licence at the time of appointment.
