Mycoplasma Genitalium Test

Mycoplasma Genitalium Test

Mycoplasma Genitalium Test, Mycoplasma genitalium (MG) is a type of bacteria that can infect the genital and urinary tracts in both men and women. It is considered a sexually transmitted infection (STI) and can lead to various health issues if left untreated, such as pelvic inflammatory disease (PID) in women and urethritis in both men and women.

Testing for Mycoplasma genitalium typically involves a sample collection from the genital area. The most common methods used for testing include:

  1. Nucleic Acid Amplification Tests (NAATs): This is the most accurate method for detecting MG. NAATs identify the genetic material (DNA or RNA) of the bacteria in a sample. The sample can be urine, vaginal swab, cervical swab, or urethral swab, depending on the person’s gender.
  2. Polymerase Chain Reaction (PCR): PCR is a type of NAAT that amplifies the genetic material of the bacteria, making it easier to detect even small amounts of the organism in a sample.
  3. Transcription-Mediated Amplification (TMA): TMA is another type of NAAT that detects the genetic material of the bacteria and amplifies it for easier detection.
  4. Nucleic Acid Hybridization: This method involves the use of specific probes that bind to Mycoplasma genitalium DNA or RNA, allowing for its detection.

It’s important to note that not all routine STI tests include Mycoplasma genitalium testing. If you suspect you might have been exposed to MG or are experiencing symptoms such as unusual genital discharge, pain during urination, pelvic pain, or other discomfort in the genital area, it’s recommended to consult a healthcare professional. They can determine if testing for Mycoplasma genitalium is appropriate based on your symptoms, sexual history, and other relevant factors.

Symptoms of Mycoplasma Genitalium:

Mycoplasma genitalium is a type of bacteria that can infect the genital and urinary tract, leading to various symptoms. It is considered a sexually transmitted infection (STI). Common symptoms associated with Mycoplasma genitalium infection include:

  1. Urethritis: Inflammation of the urethra, which can cause symptoms like pain or a burning sensation during urination, frequent urination, and discharge from the penis (in males).
  2. Cervicitis: Inflammation of the cervix, which can lead to abnormal vaginal discharge, bleeding between periods, and discomfort or pain during intercourse.
  3. Pelvic Inflammatory Disease (PID): In some cases, Mycoplasma genitalium infection can lead to PID, an infection of the reproductive organs in females. Symptoms may include lower abdominal pain, pelvic pain, painful intercourse, fever, and unusual vaginal discharge.
  4. Vaginitis: In females, this infection can cause inflammation of the vagina, leading to itching, burning, and abnormal vaginal discharge.
  5. Proctitis: Infection of the rectum, which can cause discomfort, pain, and discharge from the rectum.
  6. Asymptomatic Infection: It’s worth noting that many people infected with Mycoplasma genitalium may not experience any symptoms, which makes it important to undergo regular STI testing, especially if you’re sexually active.

Why I need a Mycoplasma Genitalium Test:

A Mycoplasma genitalium test is performed to diagnose and determine the presence of Mycoplasma genitalium, a type of bacteria that can cause sexually transmitted infections (STIs) in the genital and urinary tracts. Here’s why you might need such a test:

  1. Symptoms: If you are experiencing symptoms such as a burning sensation during urination, unusual genital discharge, pelvic pain, or pain during sexual intercourse, a Mycoplasma genitalium infection could be a potential cause. However, these symptoms are not unique to Mycoplasma genitalium and could be caused by other STIs or conditions, so testing is necessary for accurate diagnosis.
  2. STI Screening: Routine STI testing is recommended, especially if you are sexually active with multiple partners or engage in unprotected sex. Mycoplasma genitalium is not typically included in standard STI panels, so if you are concerned about this specific infection, you should ask your healthcare provider to include it in your screening.
  3. Treatment Consideration: Accurate diagnosis is crucial for appropriate treatment. Mycoplasma genitalium has shown resistance to some antibiotics commonly used to treat other STIs. Testing can help identify the specific strain of the bacteria and determine which antibiotics are most effective in treating the infection.
  4. Partner Notification: If you are diagnosed with Mycoplasma genitalium, it’s important to inform your sexual partners so that they can also get tested and treated if necessary. This helps prevent the spread of the infection.
  5. Preventive Measures: If you test positive for Mycoplasma genitalium, your healthcare provider may advise you to abstain from sexual activity or use condoms until the infection is cleared. This can help prevent transmitting the infection to others.
  6. Chronic Infection Monitoring: In some cases, Mycoplasma genitalium infections can become chronic or recurrent. Regular testing may be recommended for individuals who have had a previous infection to monitor for any recurrence.


Testing for Mycoplasma genitalium, a sexually transmitted infection (STI), is important for early detection and treatment. If left untreated, it can lead to various complications including pelvic inflammatory disease, urethritis, and potential infertility. The tests commonly used to detect Mycoplasma genitalium include nucleic acid amplification tests (NAATs) that detect the genetic material of the bacteria.

As with any medical test, there are certain considerations and potential risks to be aware of:

  1. False Positives and False Negatives: No test is perfect. False positive results (indicating an infection when there is none) and false negative results (indicating no infection when there is one) can occur. These inaccuracies can lead to unnecessary anxiety or delayed treatment.
  2. Privacy Concerns: Getting tested for STIs involves sharing sensitive information, which could potentially affect your privacy. It’s important to ensure that your healthcare provider maintains confidentiality.
  3. Cost: Depending on your location and healthcare coverage, STI tests can be expensive. It’s important to consider the cost implications before undergoing testing.
  4. Emotional Impact: Receiving a positive test result for an STI can be emotionally distressing. It’s important to be prepared for the potential emotional impact and have a support system in place.
  5. Stigma: There can still be social stigma surrounding STIs. A positive test result might lead to feelings of shame or embarrassment. It’s crucial to remember that STIs are common and can happen to anyone sexually active.
  6. Treatment and Follow-Up: If the test comes back positive, treatment is usually required to clear the infection. Follow your healthcare provider’s instructions closely to ensure the infection is properly treated.
  7. Partner Notification: If you test positive, it’s important to notify your sexual partners so they can also get tested and treated if necessary. This can be a difficult conversation to have.
  8. Testing Accuracy: While modern testing methods are generally accurate, no test is 100% foolproof. It’s essential to follow up on any symptoms or concerns even if a test result comes back negative, especially if your symptoms persist.

What does the Mycoplasma Genitalium Test Results Mean?

A Mycoplasma genitalium (MG) test is conducted to determine the presence of the Mycoplasma genitalium bacterium in a person’s genital area. Mycoplasma genitalium is a sexually transmitted bacterium that can cause various infections in the reproductive and urinary tracts. The test result can provide information about whether someone has been infected with this bacterium.

The test result will typically fall into one of these categories:

  1. Positive: A positive result means that the test has detected the presence of Mycoplasma genitalium in the sample taken from the genital area. This indicates an active infection with the bacterium.
  2. Negative: A negative result means that the test did not detect the presence of Mycoplasma genitalium in the sample. However, it’s important to note that false negatives can occur, especially if the bacterium is present in low quantities or if the sample collection was not done properly.
  3. Indeterminate or Equivocal: In some cases, the test result might be inconclusive, meaning that it’s neither definitively positive nor negative. This could be due to various factors such as borderline levels of the bacterium in the sample.

It’s important to interpret the test result in the context of the individual’s clinical symptoms, sexual history, and any other relevant factors. If you receive a positive result, it’s recommended to consult a healthcare professional for further evaluation and guidance on treatment options.
