When you’re being evaluated for Lyme disease, your healthcare provider takes a comprehensive approach. This process, often referred to as a Diagnosis Exam, involves several key steps to accurately determine if you have contracted the illness. It’s not just one single test, but a careful consideration of various factors.
Your healthcare provider will primarily focus on:
- Understanding your Symptoms: They’ll inquire about the specific signs and symptoms of Lyme disease you are experiencing. This includes noting the onset, severity, and nature of symptoms like fatigue, fever, headache, joint pain, and the characteristic erythema migrans rash.
- Assessing Exposure Risk: A crucial part of the diagnosis exam is determining the likelihood of exposure to infected blacklegged ticks. This involves discussing your geographical location, outdoor activities, and any known tick bites. Areas known to have higher tick populations and activities that increase tick exposure, such as hiking or gardening, are important considerations.
- Differential Diagnosis: It’s important to rule out other conditions that might present similar symptoms. Your healthcare provider will consider the possibility that other illnesses could be causing your symptoms, making the diagnosis exam a process of elimination as well.
- Laboratory Testing (When Necessary): Blood tests play a role in confirming a Lyme disease diagnosis, but they are not always the first step.

The Role of Lab Tests in Lyme Disease Diagnosis
The Centers for Disease Control and Prevention (CDC) recommends using FDA-cleared antibody tests as part of the laboratory diagnosis exam for Lyme disease. These tests are designed to detect antibodies your body produces in response to a Lyme disease infection.
It’s important to understand that the timing of these tests is critical. Similar to antibody tests for other infections, the accuracy of Lyme disease antibody tests is dependent on the duration of the infection. In the early stages, particularly within the first few weeks of infection when the erythema migrans rash may appear, antibody tests might produce false negatives. However, FDA-cleared tests generally achieve good sensitivity after 4 to 6 weeks post-infection.
Once an antibody test comes back positive, it’s likely to remain positive for an extended period – potentially months or even years – even after the Lyme bacteria are no longer active in your body and treatment is complete.
It’s also worth noting that some laboratories, especially those that don’t accept private insurance, might offer tests that are not FDA-cleared or approved. For the most reliable diagnosis exam, it’s generally recommended to use FDA-cleared tests.
Understanding Your Lyme Disease Diagnosis Results
For patients who receive antibiotic treatment in the early stages of Lyme disease, the prognosis is usually excellent. Most individuals experience rapid and complete recovery. Even when treatment is initiated in later stages of the disease, the majority of patients respond well to antibiotics. However, in some cases, individuals might experience long-term effects, particularly if the nervous system or joints have been significantly affected before diagnosis and treatment.
It’s crucial to remember that a positive antibody test result, even after successful treatment, doesn’t mean you are still infected. The continued presence of antibodies in your blood simply reflects your immune system’s response to a past infection. Unfortunately, these antibodies do not reliably prevent future Lyme disease infections if you are bitten by another infected tick. Therefore, continued vigilance and preventative measures against tick bites are essential, even after a previous Lyme disease diagnosis and treatment.
Tickborne Co-infections: Another Consideration in Diagnosis
When undergoing a diagnosis exam for Lyme disease, it’s also important to be aware of the possibility of tickborne co-infections. Blacklegged ticks are known to transmit not only Lyme disease but also several other tickborne diseases. Contracting multiple tickborne diseases simultaneously is referred to as a co-infection. The prevalence of co-infections can vary depending on geographical location and time.

Anaplasmosis is the most common co-infection associated with Lyme disease, affecting up to 10% of Lyme disease patients. Other less frequent co-infections include babesiosis, Powassan virus disease, and hard tick relapsing fever.
Interestingly, Lyme disease and anaplasmosis are treated with the same antibiotic. Therefore, if you are being treated for Lyme disease, you will also be treated for anaplasmosis concurrently, regardless of whether specific tests for anaplasmosis were performed during your diagnosis exam. Babesiosis, being a parasitic infection, requires different medications for treatment. If your Lyme disease symptoms persist even after antibiotic treatment, it’s important to consult your healthcare provider to explore the possibility of co-infections or other underlying issues.
While some healthcare providers might test for Bartonella or Mycoplasma co-infections, current scientific evidence does not support tick transmission for these pathogens. If you have been diagnosed with these co-infections in the context of a tick bite, seeking a second medical opinion might be beneficial.
Your state or county health department remains the most reliable resource for information about tickborne diseases prevalent in your specific area. They can provide valuable insights relevant to your diagnosis exam and local risks.
Seeking Medical Expertise for Lyme Disease
In regions where Lyme disease is commonly encountered, most family physicians, general practitioners, and pediatricians possess the necessary expertise to diagnose and manage Lyme disease effectively. They are often well-versed in conducting a thorough diagnosis exam and initiating appropriate treatment.
However, in areas where Lyme disease is less common, or in more complex or persistent cases, infectious disease specialists are frequently the most qualified medical professionals to consult. These specialists have in-depth knowledge and experience in diagnosing and treating Lyme disease and related conditions.
It is important to note that the CDC cannot endorse or evaluate individual doctors. However, resources like the National Institutes of Health offer guidance on choosing a doctor. Additionally, your state medical board can assist in verifying the standing of your healthcare provider. Ensuring you receive care from qualified professionals is a vital part of navigating your Lyme disease diagnosis exam and treatment journey.
