What Do The Results Mean
The Centers for Disease Control and Prevention recommends a two-test process of your sample:
- If your first test result is negative for Lyme disease, you don’t need any more testing.
- If your first result is positive for Lyme disease, your blood will get a second test.
- If both results are positive for Lyme disease and you also have symptoms of infection, you probably have Lyme disease.
Positive results don’t always mean a Lyme disease diagnosis. In some cases, you can have a positive result but not have an infection. Positive results may also mean you have an autoimmune disease, such as lupus or rheumatoid arthritis.
If your lumbar puncture results are positive, it may mean you have Lyme disease, but you might need more tests to confirm a diagnosis.
If your health care provider thinks you have Lyme disease, he or she will prescribe antibiotic treatment. Most people who are treated with antibiotics in the early stage of disease will make a complete recovery.
What To Think About
- It may be hard to tell if you have Lyme disease. False-positive and false-negative Lyme disease test results are common. Many people do not make antibodies to Lyme disease bacteria for up to 8 weeks after being infected.
- Doctors often do not rely on test results alone when recommending treatment for a person who may have Lyme disease. Treatment is often based on a person’s symptoms, the time of year, having a tick bite, and other risk factors for Lyme disease.
How To Prevent Dogs From Having Ticks
While it is healthy to bring your dog out often to play, keeping them indoors most of the time is still the best way to avoid ticks. After a fun walk outside, thoroughly check them for any signs of ticks or itching as the longer a tick stays attached to your dog, the higher risk of developing a disease.
Ticks attach to grass, shrubs, etc. and latch on to nearby animals so it would be best to maintain a clean environment to avoid harboring ticks.

How To Test For Lyme Disease
Wondering how to get tested for Lyme disease? The Centers for Disease Control and Prevention suggests a two-step testing process to check for a Lyme disease infection, both of which involve antibody testing , typically done on the same blood sample.
If the first step in the process returns a negative test result, then the second step is not necessary. However, if the first step yields a positive result, the second test is recommended as confirmation of a Lyme disease diagnosis. The Everlywell Lyme Disease Test follows this recommended protocol from the CDC, so it includes the two-step testing process.
Indirect Testing Can Be More Limited Than Direct Testing
Both tests used in the CDC recommended two-step process are indirect methods of diagnosismeaning they do not detect the actual Lyme disease bacteria itself but, instead, measure the bodys immune system response to the presence of disease-causing bacteria. However, a number of factors can prevent the body from producing antibodies, including the following:
- Timing: If conducted in the early stages of Lyme disease, a patients body may not have developed a sufficient enough number of antibodies to detect. This issue can be compounded by the lack of sensitivity of the ELISA test.
- Immunity Suppression: The saliva of infected ticks contains specific immune-suppressing components that can delay or prevent the activation of a persons immune response. These components are designed to prevent the body from effectively fighting off the Lyme disease-causing bacteria, so it has a chance to take hold.
- Antibiotics: If patients are taking antibiotics at the time of the Lyme disease test, they may not produce enough antibodies to be detected by the test.
- Modified Form of Borrelia: In some patients, the Borrelia bacteria will transform into a cyst, which will prevent the bodys immune system from producing antibodies.
- Weakened Immune System: False negatives can also result in patients in whom the immune system is weakened or compromised due to coinfection with another illness.
- Seronegative patients: These patients do not produce antibodies.

When Not To Take This Lyme Disease Test
Do not take this Lyme disease antibody test if:
- You are experiencing a round rash after a tick bite, such as the typical bullseye rash associated with early Lyme disease. Seek immediate medical attention instead of taking this test. A round rash could be a sign of Lyme disease, and it’s best to consult a medical professional and receive treatment as soon as possible to help prevent complications associated with the disease.
- You suspect you might have been infected with Lyme disease bacteria less than 6 weeks ago . The antibodies detected by this test take several weeks to build up in your bloodstream, taking the test before 6 weeks have passed may result in a false negative.
- You havenât lived in or traveled to an area where Lyme disease occurs. Consider discussing any symptoms with your healthcare providerâinstead of taking this testâto help determine if youâve been exposed to a Lyme disease bacterium.
- Youâve previously received a Lyme disease diagnosis, was treated for the disease, and are still symptomatic. Consider discussing any new or ongoing symptoms with your healthcare provider instead of taking this test.
- You are currently being treated for Lyme disease infection or taking antibiotic treatment for other infections. Consider discussing any symptoms with your healthcare provider instead of taking this test.
Because interpreting Lyme disease test results can be difficult, weâve designed your test results to be easy to read and understand.
Submitting Ticks To A Provincial Public Health Laboratory
If possible, send any ticks that you have removed to a public health laboratory in your area. However, tick identification and testing is not done in all provinces of Canada.The following provinces accept submissions:
Contact your local public health authority for details on:
- the tick identification and testing program available in your area
- how to submit a tick for testing
The public health laboratory will:
- identify the tick
- forward only blacklegged ticks to the National Microbiology Laboratory for testing

How Is It Diagnosed
If youâve been outside in an area where ticks are known to live, you should tell your doctor. Theyâll also want to know about the symptoms youâre having. These details are crucial to making a diagnosis of Lyme disease.
Early symptoms that usually occur within the first month after a tick bite can include:
- Rash at the site of the tick bite that may look like a âbullâs-eyeâ
- Racing heart
- Problems with your short-term memory
Symptoms that come and go are common with Lyme disease. They will also depend on the stage of the disease.
Using Cbd Oil In Your Dogs Treatment Plan
There is anecdotal evidence that suggest CBD is a holistic solution that can improve your dogs overall mood and increase their appetite. The increase in appetite is important because Lyme disease in dogs can reduce their appetite. Although CBD oil is not a treatment for Lyme disease in dogs, it can help stimulate appetite and can help mitigate any pain or discomfort your dog may be feeling. If your dog has been diagnosed with Lyme disease you should speak with your trusted veterinarian to come up with a treatment plan that suits your dog.

Her ordeal is a common one every year, some 300,000 people in the United States are diagnosed with Lyme disease, according to the Centers for Disease Control and Prevention, and that number is on the rise. Some people wait months or years to get a correct Lyme diagnosis. And their cases highlight a problem: Tests for Lyme in the first month of infection are frequently wrong. When diagnosed and treated early the infection is a simple one to get rid of, but left untreated it can cause a myriad of lingering symptoms, from severe arthritis to short-term memory problems.
Now, a number of research groups are working to improve Lyme tests to catch infections in the early stages. One avenue being studied by the CDC aims to create a Lyme signature of small molecules in the blood an approach that, in early testing, catches a dramatically higher share of early infections.
How It Is Done
The health professional taking a sample of your blood will:
- Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
- Clean the needle site with alcohol.
- Put the needle into the vein. More than one needle stick may be needed.
- Attach a tube to the needle to fill it with blood.
- Remove the band from your arm when enough blood is collected.
- Put a gauze pad or cotton ball over the needle site as the needle is removed.
- Put pressure on the site and then put on a bandage.

Enzyme Immune Assay Testing:
This test detects antibodies to the different kinds of bacteria that are known to cause symptoms of Lyme disease. Different strains of Borrelia are found in the USA and Europe but the tests are designed to detect all of the Borrelia that cause symptoms.
The EIA is the first test performed as it is designed to be very sensitive . If the EIA test is negative for Lyme disease, this can be relied upon to exclude Lyme disease in the patient, especially if the sample is taken when symptoms have been present for several weeks.
The disadvantage of the EIA is because it is very sensitive it can give false positive results. This means that the EIA test is reacting with something else present in the blood sample which is not related to Lyme disease. False positive EIA results can happen when there are infections with other bacteria or viruses, or in certain inflammatory /automimmune conditions. This is why a positive EIA test should be confirmed by a second test the Western Blot.
In Ireland, 2.5% of over 4,800 people who were tested by the National Virus Reference Laboratory in a single year had a positive Lyme test result. In Europe, between 3- 5% of the general population show evidence of infection with Borrelia bacteria at some point in their lifetime while a study in Ireland previously found that the background rate of infection in the Irish population was 3.4%.
Lyme Disease Pcr Testing
A polymerase chain reaction test, also known as a PCR test, checks blood for evidence of a pathogens DNA. In some cases, a PCR test will be performed using a sample of synovial fluid, which is found in the joints. This test has become very common in the past two years because of the COVID-19 pandemic. Millions of people have had to undergo PCR testing for coronavirus.
A Lyme disease PCR test is designed to look for the borrelia bacterias DNA to identify whether or not it has made its way into the body through a bite from an infected tick. When DNA material is found, it can be determined that a Lyme infection is present.

Are There Any Risks To Lyme Disease Tests
There is very little risk to having a blood test or a lumbar puncture. If you had a blood test, you may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. If you had a lumbar puncture, you may have pain or tenderness in your back where the needle was inserted. You may also get a headache after the procedure.
What Is A Tick
- A tick is a parasite that is 3 to 5 mm in size. They are so small that it can be hard to spot them immediately.
- They are the most common trouble for pets, especially the ones that roam outside more often.
- They feed on animals blood. Often time they go unnoticed because of their small size and painless bites.
- There are also different types of ticks. A deer tick is a common kind in the United States.

Lyme Disease Testing & Results
To get the Lyme disease test near you, simply order online and get tested at the selected Quest Diagnostics lab location. Once the Lyme disease test results are available, they will be available for download. Many people wonder whether fasting is required and how long results take for the Lyme test. Fasting is not required when getting a Lyme disease blood test and results are typically available in 4 business days or less. As can be seen on the sample Lyme disease screening test report above, the Lyme antibody screen will report the antibody levels which can be compared against a reference range provided by the lab. If Lyme disease antibodies are detected, the Lyme western blot test will be performed and reported to provide more detail. This Lyme disease test is a component of the more comprehensive infection panel test that screens for a variety of infections.
In most cases, Lyme disease can be treated effectively with common antibiotics such as doxycycline, cefuroxime and amoxicillin. The risk of being exposed to Lyme disease in the first place can be reduced by avoiding regions with infected ticks. When in an at-risk location, it is recommended to wear a hat, long sleeve shirts and long pants and to use insect repellants like DEET. A recombinant Lyme vaccine used to exist but is no longer available.

So When Do You Need Blood Tests For Lyme Disease
In some cases, you can have Lyme disease without the rash. Or you may not see the rash before it goes away on its own.
In these cases, your doctor should ask you about your medical history and do a thorough physical exam. Your doctor should look for these signs that you might have Lyme disease:
- You were in an area with ticks and Lyme disease.
- You also have fever or redness, warmth, and swelling in one or a few joints at a time usually the knees, shoulders, or wrists.
Other symptoms can occur later on. Talk to your doctor about testing and treatment choices.

Can Lyme Disease Be Detected By A Blood Test
In a word: yes!
A blood test does not only detect Lyme disease it is the most accurate and preferred test for diagnosing the disease. If a patient with Lyme disease shows signs that the central nervous system has been affected by the disease, western blot testing on the cerebrospinal fluid can be performed. If ordering from Walk-In Lab, a doctors note is not needed. Just pick your Lyme disease test and place your order online.
Lyme Disease Blood Test
The Lyme disease test, also known as a Lyme disease blood test, Lyme disease screening test and a Lyme test, measures Lyme disease antibody blood levels.
Lyme disease is an infection spread by ticks containing the Borrelia burgdorferi bacteria. Sometimes known as Lyme borreliosis, Lyme disease usually infects humans when the tick has been attached for at least 36 hours. Unlike other types of infectious diseases, Lyme disease cannot be transmitted between humans or animals.
Lyme disease can cause a wide range of symptoms targeting a number of different organs and systems in the body. Classically, Lyme disease presents with an bullseye-shaped rash around the area of the tick bite known as erythema migrans although not every person gets one. Untreated, Lyme disease can lead to chronic joint pain, heart abnormalities, memory problems and long-term fatigue.

Risk Factors For Post
Youre at a greater risk for post-treatment Lyme disease syndrome if youre infected by the bite of a diseased tick. If the infection progresses to the chronic stage, your symptoms might continue for weeks, months, or even years after the initial tick bite.
You may also be at a higher risk for these long-term symptoms if youre not treated with the recommended antibiotics. However, even people who receive antibiotic therapy are at risk. Because the cause of post-treatment Lyme disease syndrome is unknown, theres no way to determine whether it will progress to the chronic stage.
Typically, the symptoms of post-treatment Lyme disease syndrome resemble those that occur in earlier stages. People with persistent symptoms often experience lingering episodes of:
Dont Miss: How Long Does A Lyme Blood Test Take
The Swiss Agent: Long
Lyme disease is a serious problem here in the United States and we really need to find solutions to some of the limitations that we have, particularly in diagnosing this infection, said Claudia Molins, a microbiologist at the CDC. We want a test that can be used within the first two weeks of infection and that does not rely on antibody production.
So Molins and her colleagues are focusing on metabolomics an approach that, rather than testing directly for the immune response to the infection, instead looks for a wide spectrum of collateral damage.
Specifically theyre looking for so-called metabolite biosignatures: the litany of sugars, peptides, lipids, amino acids, fatty acids, and nucleotides normally present in the blood.
Infections like Lyme, the thinking goes, change the levels of these things and they do so in a predictable, measurable way.
Molins and her team tested that hypothesis by tapping a unique CDC resource freezers filled with well-characterized blood serum samples. They used serum from 89 early Lyme patients, within the first month of infection, and 50 healthy controls to develop an algorithm to detect Lyme blood signatures.
The researchers then tested that algorithm on a larger sample of serums and found that they could diagnose 88 percent of early Lyme cases, and could differentiate Lyme from other diseases 93 percent of the time. The results were published in a 2015 study in Clinical Infectious Diseases.
