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 itâs 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 havenÃ¢t lived in or traveled to an area where Lyme disease occurs. Consider discussing any symptoms with your healthcare providerÃ¢instead of taking this testÃ¢to help determine if youÃ¢ve been exposed to a Lyme disease bacterium.
- YouÃ¢ve 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, weÃ¢ve designed your test results to be easy to read and understand.
Do I Need To See An Infectious Disease Specialist To Get Tested For Lyme Disease
No, you do not need to see an infectious disease specialist.
As noted above, any type of physician should be able to order the correct diagnostic tests, interpret your test results, and provide antibiotics to treat Lyme disease. This is especially true the earlier the disease is caught.
In fact, American Lyme Disease Foundation points out that waiting for an appointment with an infectious disease or other type of specialist can actually delay your diagnosis and treatment. If you were bitten by a tick, notice symptoms of Lyme disease, or believe youre at risk for Lyme or another tick-borne disease, its important that you make an appointment with a doctor immediately even if its your primary care physician.
That said, there are plenty of reasons why you may want to consult with, or get a second opinion from, someone with specific experience with Lyme disease. In other words, you may want to make an appointment with a Lyme-literate doctor . Read on to learn more.

Lyme Disease Signs And Symptoms
Most symptoms of Lyme disease in humans usually appear between three and 30 days after a bite from an infected blacklegged tick.
You should contact your local public health unit or speak to a health care professional right away if you have been somewhere that ticks might live and experience any of the following symptoms:
- a bulls-eye rash (a red patch on the skin that is usually round or oval and more than 5 cm that spreads outwards and is getting bigger
- a bruise-like rash
- another type of unusual rash
- muscle aches and joint pains
- spasms, numbness or tingling
- facial paralysis
If not treated, Lyme disease can make you feel tired and weak and, if it gets really bad, it can even harm your heart, nerves, liver and joints. Symptoms from untreated Lyme disease can last years and include recurring arthritis and neurological problems, numbness, paralysis and, in very rare cases, death.

The Best Test For Lyme Disease
Lyme disease is a tick-borne illness spread by Lyme borreliaebacteria which includes, but is not limited to, Borrelia burgdorferi sensu stricto. The Centers for Disease Control and Prevention estimate that there are 400,000 cases of Lyme disease annually, making Lyme a serious public health concern that only stands to grow as the spread of ticks affects disease endemicity and seasonality.
One of the biggest challenges of fighting Lyme disease is providing patients with accurate diagnostic tests. Without access to the best tests for Lyme disease, its impossible to diagnose this treatable disease in a timely manner. When the disease isnt caught in time, it can spread throughout the body and cause chronic health problems that could otherwise be avoided with earlier detection and treatment.
Submit A Tick Photo For Identification
You can submit photographs of ticks for rapid photo identification through the eTick website or using the eTick app.
- Download the eTick app on or the Apple Store
How to submit a tick photo to eTick:
- Take a photograph of the tick using your smart phone or digital camera. Instructions on how to take a good photo for species identification are provided in the eTick photographic guide.
- If you are not using the eTick app, submit your photo on the eTick website.
- After submitting your photo, keep your tick specimen for at least 5 days in case additional photos are needed to complete the identification.
- Save the tick in a clean, empty and secure container. Do not add any ventilation holes to the container. Ticks can be stored in the refrigerator or freezer.
- Submitted photographs will be used to identify the tick species and you will get the results typically within 24 hours. Once you receive your results, the tick can be discarded, or if requested, submitted to the laboratory.
- If the tick is identified as a type that can transmit the bacteria that causes Lyme disease, or cannot be identified by photo, you will be asked to submit the tick for additional testing to the Alberta Public Health Laboratory.

If My Dog Tests Positive Does He Need To Be Treated
The decision to treat Lyme disease is somewhat controversial since many infected dogs show no signs of illness. Factors that would support treatment include:
a moderate to high value of QC6 signs of illness compatible with Lyme disease at the time of testing a history of illness compatible with Lyme disease within the past year the presence of abnormal levels of protein in the urine.
Molecular Testing For Detection Of Borrelia Species Bacterial Dna
PCR is available for Borrelia species DNA detection but is of limited value in routine testing for Lyme disease because the organism is only present in blood during the early stages of the disease and is predominantly restricted to the affected tissues.
Diagnostic molecular testing for Borrelia species DNA is available on request for relevant specimen types. Please call RIPL to discuss individual cases.

Investigation Of Suspected Lyme Disease
Erythema migrans is a clinical diagnosis and does not require confirmation by laboratory testing. Lyme disease is not a notifiable disease so there is no statutory requirement to notify clinically suspected cases to the local Health Protection Team.
The 2018 NICE Lyme disease guideline provides detailed advice about when a diagnosis of Lyme disease should be suspected and about which tests to use and when.
The NICE Lyme disease guideline also contains a useful summary diagram of the routine serological testing recommendations for Lyme disease.
How Will Pregnancy Affect Treatment For Lyme Disease
Early treatment of Lyme disease during pregnancy is important. Thats because if Lyme disease is left untreated, it can affect the placenta. According to the CDC , transmission of Lyme disease from mother to fetus is possible, though rare.
For pregnant people, treatment includes a round of antibiotics. Certain treatments for Lyme disease may not be used, as they can affect the fetus. If you suspect that you have Lyme disease, talk with a healthcare professional immediately.

The Most Common Lyme Disease Blood Tests
The two most common diagnostic tests for Lyme disease are the enzyme-linked immunosorbent assay and the Western blot. These Lyme disease tests allow physicians to visualize the reaction between antibodies in an infected persons blood to specific antigens or parts of the bacteria that cause Lyme disease.
In the case of the Western blot, for example, antigens are separated by size and then transferred onto a membrane strip. When an antibody reacts with an antigen on the strip, that band will turn dark purple. For test results to be positive, a specific combination of bands on the membrane strip must be present.

As an avid outdoorsman, Justin Wood spent his summers tree planting in the northern Ontario wilderness. A lover of the outdoors and science, he moved to Calgary in 2010 for the mountains and to pursue a masters degree in genetics and molecular biology at the University of Calgary. Sports and outdoor adventure were his lifeuntil a bite from a tiny arachnid stole his mobility, cognitive abilities and deteriorated his quality of life.
Beginning with acute neurological issues, Justins symptoms progressed in severity and breadth until he was unable to participate in athletics, academics, work or take care of himself. He experienced extreme constant headaches, brain fog, cognitive impairment, sensitivity to stimulation, insomnia, joint pain, muscle pain, spasms and tremors, heart palpitations and extreme fatigue.
It took over 20 doctors, four years and an international blood test to diagnose the culprit: Lyme disease. Although Lyme disease is the most common tick-born infection in Canada, it is vastly under-detected.

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.

Laboratory Testing In Vaccinated Individuals
In 1998 the Food and Drug Administration approved a recombinant OspA vaccine for use in patients at risk of acquiring LD . Since the efficacy of the vaccine is reported to be in the range of 76% after three doses, there will be instances where vaccinated individuals acquire natural infection with B. burgdorferi sensu lato. ELISAs and IFA assays utilizing OspA-producing strains of B. burgdorferi sensu lato will not discriminate between vaccinated and naturally infected individuals. Therefore, the CDC two-step algorithm is not applicable to vaccinated patients and immunoblotting must be relied on for serologic confirmation of infection. In addition to increasing costs, the issue is complicated further by reports that some vaccinated patients produce antibodies that bind to various borrelial proteins, making interpretation of immunoblots more difficult . This will continue to be problematic until ELISAs and other first-line assays based on non-OspA-producing strains or recombinant borrelial proteins are in widespread use and physicians become aware of the specific limitations of the testing methods provided by their laboratories .
Serological Testing Of Csf For The Diagnosis Of Neurological Lyme Disease
Serological testing for neurological Lyme disease is based on demonstrating intrathecal synthesis of Borrelia-specific antibodies in CSF. For laboratory testing for neurological Lyme disease, separate IgG and IgM ViraChipÂ® serology assays are performed on CSF and paired serum and the results compared.
CSF samples must be tested in parallel with a contemporaneous serum sample and protein and immunoglobulin levels compared between the two sample types to produce a meaningful result.

Where Can I Get A Tick Tested For Lyme Disease
Where can i get a tick tested for lyme diseasePeople can have an impaired immune system from an overactive and underactive immune response. A strong immune system responds appropriately to the challenge a weak immune.
Diagnosing and treating a tick-borne disease can be highly complex. Having a doctor who is trained and experienced in caring for patients with these illnesses can help ensure that you achieve the best possible health outcome. Luckily, there is a growing number of Lyme disease experts who can provide diagnostic testing and proper treatment for Lyme and other tick-borne.
People who have removed a tick sometimes wonder if they should have it tested for evidence of infection. Although some commercial groups offer testing, in general this is not recommended because: Laboratories that conduct tick testing are not required to have the high standards of quality control used by clinical diagnostic laboratories.
If no clinical signs of Lyme disease are observed, different approaches can be tried: A different antibiotic can be used, treatment time can be extended, or the animal is not treated again but its antibody status is monitored every 6-12 months .
Lyme disease cant be transmitted from one pet to another, nor from pets to humans, except through tick bites. However, a carrier tick could come into your house on your dogs fur and get on you.
Future Possibilities For Diagnostic Tools
NIAID-supported scientists have identified genome sequences for multiple strains of B. burgdorferi. Greater advances in diagnostics are anticipated as genetic information is combined with advances in microarray technology, imaging, and proteomics. These growing fields of science are expected to lead to improved diagnostic tools as well as provide new insights on the pathogenesis of Lyme disease. Examples of tools being developed with NIAID support include use of metabolomics to characterize new biomarkers of infection, next generation T-cell based measurements, and novel antigens for improved measurement of effective treatment.

What Is Lyme Disease
This bacterial infection is spread through the bite of a young deer tick or black-legged tick. These eight-legged creatures, about the size of a poppy seed, can be found in wooded and grassy areas throughout the United States, especially in New England and the Rocky Mountains.
Because these ticks are so small, most people donât realize when theyâre bitten. But the longer a tick stays attached to you, the more likely it is to transmit Borrelia burgdorferi , if the tick is a carrier.
Positive C6 Elisa On Serum
RIPL will automatically proceed to do IgM and IgG immunoblot tests after a positive or indeterminate ELISA test and will provide an overall interpretation of the ELISA and immunoblot in the light of the clinical details provided on the request form.
Please provide clinical details to allow the interpretation of serological results. These are needed for interpretation because antibody levels from a protective humoral immune response to Borrelia species may persist indefinitely in patients who have had Lyme disease in the past. After successful treatment of Lyme disease antibody concentrations may slowly fall over time.
Borrelia species are notifiable organisms. The numbers of positive results from laboratory confirmed cases in RIPL are reported to PHE and analysed for inclusion in PHE Health Protection Reports as part of Lyme disease epidemiology and surveillance.

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.
How Do You Diagnose The Later Stages Of Lyme Disease
Disseminated Lyme disease, due to unsuccessful or delayed treatment, can become disabling. The bacteria can leave the skin where it was initially inoculated by the tick and travel through the bloodstream to numerous systems of the body, primarily joints, heart, brain, muscles and the nervous system.
Late disseminated Lyme disease has a wide range of presentations including joint pain, extreme fatigue, neuromuscular pain, cardiac problems, headaches, and other central nervous system dysfunction. There are some distinguishable signs of later stage Lyme disease including facial palsy in the second stage, and swollen knees in the third stage that are somewhat specific for Lyme disease, but not absolutely, because there are other causes of Bells Palsy and swollen knees.
Diagnosis can be confirmed by serology blood tests which measure the antibodies that are formed by the immune system in response to the Lyme disease bacterial infection. Collection of cerebrospinal fluid by lumbar puncture may be indicated in neurologic cases that may involve the central nervous system.

What Do The Test Results Mean
Because there are three tests that are typically conducted for the Lyme disease blood test, then results can vary based on the combination of test results received. When all three tests are positive, then Lyme disease is likely. These other result combinations are usually interpreted in the following ways.
Positive IgM, Negative IgG, Negative Western Blot.This usually indicates that the Lyme disease infection is in its early stages or that the blood test has produced a false positive result.
Negative IgM, Positive IgG, Positive Western Blot.This is usually interpreted as having a late-stage Lyme disease infection. It may also be an indication that someone had a previous infection that has been removed from the body.
All results negative.This is usually interpreted as there not being any infection present and that the symptoms are being caused by another issue. In some specific instances, however, it can also be seen as the antibody levels being too low to detect.
Once Lyme disease is confirmed, there will almost always be detectable levels of the bacteria which causes the disease in the IgG antibodies in their blood. This will mean that their IgG blood test results will have a standard deviation in what is considered as normal because of the presence of the disease, even if it has been effectively cured.
