Ordering the Relapsing Fever Test
The Relapsing Fever test helps detect Borrelia miyamotoi, a bacteria spread by ticks that can cause recurring fevers, joint pain, and neurological symptoms. This test is especially useful for people who have symptoms that come and go, making it hard to pinpoint the cause. Interestingly, relapsing fever can sometimes be mistaken for Lyme disease, but it is caused by a different group of bacteria and may require different treatment.
Ordering this test can help you:
- Identify Borrelia miyamotoi infection, which is often missed by standard Lyme disease tests
- Distinguish between relapsing fever and other tick-borne illnesses
- Support your doctor in choosing the right treatment plan
- Track the effectiveness of treatment over time
- Reduce the risk of ongoing symptoms by catching the infection early
Who Should Consider Tick-Borne Bacteria Testing
People who have spent time in wooded or grassy areas and now experience unexplained fevers, chills, or joint pain may benefit from this test. For example, someone who enjoys hiking and later develops recurring headaches, muscle aches, and brain fog might not realize these symptoms could be linked to a tick bite weeks earlier.
Ordering this test may also be helpful in these situations:
- After finding a tick attached to your skin and developing flu-like symptoms
- If you have a rash that comes and goes, especially after outdoor activities
- When you have been treated for Lyme disease but still have symptoms
- If you experience dizziness, heart palpitations, or nausea without a clear cause
- For those who have traveled to areas where relapsing fever is more common, even if symptoms are mild or unusual
Testing for this infection can help you and your doctor find the right cause of your symptoms, leading to more targeted care and fewer delays in treatment. Waiting to order this test could mean missing the best window for early detection, which may make treatment less effective.
Preparing for Borrelia miyamotoi Blood Testing

Labs Included When Ordering Your Relapsing Fever Test
| Test Name | Reference Range | What This Biomarker Means | Low and High Levels of Relapsing Fever |
|---|---|---|---|
| Borrelia miyamotoi Antibodies (ELISA and Western Blot) | Negative | This test checks for antibodies your body makes in response to Borrelia miyamotoi, a bacteria spread by ticks. It helps show if you have been exposed or infected. |
High levels mean your immune system has responded to Borrelia miyamotoi, suggesting a current or past infection.
Low levels mean there is no sign of exposure or infection with this bacteria. |
| Borrelia miyamotoi DNA (PCR) | Not Detected | This test looks for the genetic material (DNA) of Borrelia miyamotoi in your blood. It can show if the bacteria is present right now, even before antibodies appear. |
High levels mean Borrelia miyamotoi DNA is found, showing an active infection.
Low levels mean no DNA is detected, so there is no active infection at the time of testing. |
Reference ranges may change slightly as labs update their methods and standards.
