Herpes issues?
Hello Doctor, I have some questions regarding my herpes test results.
Here’s the timeline: At the beginning of January this year, I developed a red bump on the glans of my genitalia.
On January 10th, I visited the urology department at a major hospital, where the doctor mentioned that a sexually transmitted infection (STI) could not be ruled out.
I had blood tests for syphilis, HSV, HIV, etc., all of which came back negative.
Although the doctor prescribed topical medication, by February, my condition had not improved; instead, I developed red rashes on my thighs.
On February 24th, I went to another large hospital's urology department, where I was tested for syphilis and HSV-2, and again, the results were negative.
The doctor then recommended that I see a dermatologist, who diagnosed me with scabies.
Under the treatment from the dermatologist, my condition improved.
However, from late July to early August, I experienced recurrent fevers and was eventually diagnosed with mononucleosis.
At that time (August 7th), my HSV-2 IgM was 12.3 NTU (positive > 11.0), CMV IgG was 39.6 (+), and EBV was 57.5 (+).
I had a single sexual partner from January 10th to August 7th, and I can assure you that they have not been unfaithful.
I am puzzled as to why my HSV-2 IgM is positive (without symptoms).
In my ongoing confusion, I had another test for HSV-2 on November 21st, which showed HSV-2 IgM at 1.15 RU/ml (positive > 1.10), but HSV-2 IgG was 0.50 RU/ml (negative < 0.9).
These results are baffling to me.
Could you please explain what might be happening?
Here are my test results:
- 1/10: Syphilis (-), HIV (-), HSV (-), HSV-2 IgM 2.40 NTU
- 2/24: HSV IgG Type II 4.73 NTU
- 8/7: CMV (+), EBV (+), Syphilis (-), HSV-2 IgM 12.30 NTU (+)
- 11/13: Syphilis (-)
- 11/21: HSV-2 IgM 1.15 RU/ml (+) > 1.10, HSV-2 IgG 0.50 RU/ml (-) < 0.9
These are my examination reports.

Hello: HSV may have been contracted a long time ago, but your description does not indicate any occurrence of blisters.
IgG indicates whether there has been a past infection, while IgM indicates a recent infection, which may disappear in about 5-6 weeks.
Based on your report, it is possible that the infection occurred before August 7, leading to an increase in IgM.
The subsequent test on November 21 shows that IgM levels are nearly normal, but it is better to evaluate both IgG and IgM together for a more accurate assessment.
Additionally, the presence of CMV and EBV may affect the blood test results.
Wishing you good health.

Understanding herpes results, especially in the context of a patient's journey through urology and dermatology, can be quite complex. Based on the timeline and results you've provided, it appears that you have undergone a series of tests and evaluations for various conditions, including sexually transmitted infections (STIs) and skin conditions.
Initially, you presented with a red bump on the glans of your penis, which led to a consultation with a urologist. The physician's suspicion of a possible STI was reasonable, given the symptoms. The tests for syphilis, HSV (herpes simplex virus), and HIV returned negative results, which is reassuring. However, the persistence of your symptoms and the development of a rash on your thigh prompted further investigation.
When you visited another urology department, the negative results for syphilis and HSV-2 were again noted, leading to a referral to dermatology. The dermatologist diagnosed you with scabies, a common skin infestation caused by mites, which can cause intense itching and rashes. Treatment for scabies typically involves topical medications, which you mentioned were effective.
The situation took a turn when you experienced recurrent fevers and were ultimately diagnosed with infectious mononucleosis, commonly caused by Epstein-Barr virus (EBV). During this time, your HSV-2 IgM levels were found to be elevated, which can be perplexing. IgM antibodies indicate a recent infection, while IgG antibodies suggest past exposure or infection.
Your subsequent tests showed fluctuating IgM levels for HSV-2, with the most recent test indicating a positive IgM but negative IgG. This pattern raises several possibilities:
1. False Positives: IgM tests for HSV can sometimes yield false-positive results, especially in the absence of clinical symptoms. This is particularly relevant since you have not experienced any typical herpes symptoms.
2. Recent Infection: The presence of IgM could suggest a recent infection, but given your stable relationship and the negative IgG results, this seems less likely.
3. Cross-Reactivity: Sometimes, the tests can cross-react with other viral infections, leading to elevated IgM levels without a true herpes infection.
4. Laboratory Variability: Different laboratories may have varying thresholds for positivity, which can lead to discrepancies in results.
In your case, the combination of negative IgG and fluctuating IgM levels suggests that while there may be some indication of exposure to HSV-2, it does not confirm an active or chronic infection. It is essential to discuss these results with your healthcare provider, who may recommend further testing or a different approach to monitoring your symptoms.
In conclusion, the journey through understanding your herpes results involves considering various factors, including the timing of tests, the presence of symptoms, and the reliability of the tests themselves. It is crucial to maintain open communication with your healthcare providers to clarify these results and determine the best course of action for your health. If symptoms persist or worsen, further evaluation may be warranted to rule out other conditions or infections.
