Mycoplasma genitalium test

Do you think you might be infected with Mycoplasma genitalium? It's important to know that this bacterium is usually not included in a standard STD test. Testing is often only performed if you have symptoms, a sexual partner has tested positive, or when other STDs have been ruled out.

Because the symptoms closely resemble those of chlamydia or gonorrhea, laboratory testing is necessary to determine if Mycoplasma genitalium is the cause.

When is a Mycoplasma genitalium test advisable?

A test is usually recommended when:

• You have symptoms consistent with an STD.
• A sexual partner has tested positive for Mycoplasma genitalium.
• Symptoms persist while chlamydia and gonorrhea have been ruled out.
• A doctor suspects this bacterium is the cause.

If you don't have symptoms, Mycoplasma genitalium is not always routinely tested for.

How is Mycoplasma genitalium tested?

The bacterium is detected with a PCR test, which looks for the genetic material (DNA) of the bacterium.

Depending on your symptoms and situation, a urine sample or a swab will be taken for this purpose.

What materials are examined?

Depending on the site of the possible infection, a laboratory may use:

• A first-void urine sample (especially for men).
• A vaginal swab.
• A cervical swab.
• An anal swab if symptoms are present there.

The choice of the correct material depends on your symptoms and sexual contacts.

When is the test reliable?

After a possible infection, the bacterium needs time to multiply before it can be detected.

Always follow the testing advice of a doctor or test provider. Testing too early can reduce the reliability of the result.

How reliable is a PCR test?

A PCR test is very accurate and is considered the most reliable method for detecting Mycoplasma genitalium.

When the test is performed at the right time, the chance of a reliable result is high.

How quickly will the results be available?

This varies by laboratory. In many cases, results are available within a few working days.

Your doctor or test provider will inform you about the expected waiting time.

What happens with a positive result?

If the test is positive, a doctor will discuss which antibiotics are most suitable. Because Mycoplasma genitalium is increasingly resistant to certain antibiotics, treatment can vary from person to person.

Additionally, it is important to inform recent sexual partners so that they can also get tested and, if necessary, treated.

Frequently asked questions about a Mycoplasma genitalium test

Is Mycoplasma genitalium routinely tested?

No. The bacterium is usually not part of a standard STD test.

How is the bacterium detected?

With a PCR test on urine or a swab.

Is the test reliable?

Yes. A PCR test is very reliable when performed at the correct time.

How quickly will I get the results?

This varies by laboratory, but usually within a few working days.

Should my partner also get tested?

Yes. If an infection is confirmed, it is advisable for recent sexual partners to also get tested.

A correct diagnosis prevents unnecessary symptoms

Mycoplasma genitalium is not routinely screened for, yet the bacterium can cause long-term symptoms. If you have persistent symptoms or a partner has tested positive, discuss with a doctor whether a Mycoplasma genitalium test is advisable. A timely diagnosis allows for targeted treatment.
