Think the Lyme Disease Rash is Always a Bull’s-eye? Think Again! | Johns Hopkins Rheumatology

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 borrelia-specific antibodies may persist for several years in patients who have had Lyme disease in the past, long after the bacteria have been cleared from the body. Therefore, detection of borrelia specific antibodies in someone with no evidence of current clinical symptoms or recent tick exposure argues against active Lyme disease infection. 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 UKHSA and analysed for inclusion in UKHSA Health Protection Reports as part of Lyme disease epidemiology and surveillance.

The Role Of Lyme Disease Tests

The purpose of the most common type of Lyme disease testing is to determine whether you have developed antibodies as a result of past exposure to the Borrelia bacteria that cause Lyme disease. Antibodies are proteins created by the immune system that target specific threats like bacteria and viruses.

Blood testing alone cannot determine whether you have Lyme disease. Instead, testing can provide helpful information that your doctor can consider along with other factors, such as any symptoms youve had and whether youve been exposed to ticks that can carry Borrelia, to determine if a diagnosis of Lyme disease is appropriate.

Beyond blood testing, it is possible to analyze fluid from the central nervous system for signs of the Borrelia bacteria.

Best For Lower Budgets: Cutter Lyme Disease Tick Test

The Cutter Lyme Disease Tick Test is a DNA tick test that checks whether the tick carries a Lyme disease pathogen.

The test requires a person to take one to several ticks from the same host and place them in the specimen bag. They then mail them to the lab using the pre-addressed mailing label.

Individuals can expect to receive their results through email, phone, or mail within 3 business days. The available screenings feature basic, advanced, and comprehensive test panels that check multiple pathogens.

Pros

CDC , people should perform two tests for Lyme disease, and they can use the same blood sample.

If they receive a negative result, they do not need to perform another test. However, if their first test is positive or indeterminate, it is best to test again.

The CDC states the overall result is only positive for Lyme disease when the first and second tests produce a positive result.

Tests detect IgM and IgG antibodies that the body produces in response to an infection. The IgM antibodies appear early in response to the exposure, while the IgG antibodies appear 46 weeks after the infection and can persist for years.

However, individuals may develop antibodies several weeks after exposure. Therefore, those who test before the antibodies develop can get a false-negative result.

False positives can occur if a person has other conditions, including

How Do They Test For Lyme Disease

Lyme disease is best tested using two different blood testing methods. These are:

  • The Enzyme-linked Immunosorbent Assay test: In a nutshell, this test will look for signs that your body is trying to fight off Lyme disease by producing antibodies. However, the ELISA test may come back negative even when a person is infected by the Borrelia burgdorferi bacteria. False-negatives can occur during the early stages of the disease, where the infected persons body has not produced enough antibodies to fight off the B. burgdorferi bacteria. For this reason, reliable diagnosis is not usually based only on the ELISA test results.
  • Western Blot test: Heres a simple way to explain the western blot test without getting into all the nitty-gritty details of what it does and how it does it. Put simply, it separates the blood proteins and detects antibodies to the bacteria causing the Lyme disease. Usually, when an ELISA test comes back positive, a western blot test is performed to confirm the diagnosis.

Ideally, the CDC recommends standard two-tier testing to confirm the veracity of the Lyme disease test accuracy. Together, the ELISA and western blot tests are 99.9% accurate.

Completion Of Lyme Disease Test Request Form

Choosing A Lyme Disease Test

Diagnostic samples must be submitted with a completed RIPLLyme disease test request form . Please use a single request form for each patient even when sending several samples.

Please provide details of the sample type, patients symptoms and onset date, tick bite or exposure history and, if relevant, travel and treatment history. Symptom onset date is particularly important for interpretation of laboratory results.

When sending CSF, please provide the cell count and total albumin, IgG and IgM levels for the CSF and serum pair, if available.

Ideally the clinician who sees the patient should print out and complete the appropriate request form . Send the request to the local laboratory with the clinical sample along with a local laboratory request form, whether this is paper or electronic.

The local laboratory should complete the senders information on the request form and then forward the completed form and sample to RIPL. Before sending samples, clinicians are advised to liaise with their local laboratory because local arrangements may vary.

If only immunoblot confirmation is required because the local laboratory has already obtained a positive Lyme screening test result on the serum sample being submitted, tick the Line blot confirmation only box and write the positive screening test result below.

Why It Is Done

A Lyme disease test is done to diagnose Lyme disease in people who have symptoms of Lyme disease. Symptoms may include:

  • An expanding red rash with a pale centre. This is sometimes called a “bull’s eye” rash.
  • Extreme tiredness.
  • Headache and stiff neck.
  • Muscle and joint pain.

Symptoms of chronic Lyme disease infection include joint pain, stiffness, and problems with the heart, brain, or nerves.

Testing is most accurate when you have risk factors for Lyme disease or symptoms of the disease.

What Happens During Lyme Disease Testing

Lyme disease testing is usually done on a sample of blood. In certain cases, a cerebrospinal fluid test may be done.

For a Lyme disease blood test:A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

For a CSF test:You may need a cerebrospinal fluid test if your symptoms could mean that Lyme disease is affecting your nervous system, such as a stiff neck or numb hands or feet. Providers may order a CSF test if the results of your blood test show you likely have Lyme disease or if the results are uncertain.

To get a sample of your cerebrospinal fluid, a provider will do a procedure called a lumbar puncture, also known as a spinal tap. During the procedure:

The Elisa And Western Blot Are Not Sensitive Enough

Another major limiting factor of the traditional ELISA and Western blot is the quality. These tests tend to use lysed BB cultures, and therefore, depending on the culture conditions, some antigens are over-expressed, and some are under-expressed. This, in turn, can affect the ability to detect antibodies from patients blood.

Whats more, if a patient tests too early after a tick bite, his or her body may not have produced enough antibodies to show up on a test with suboptimal sensitivity.

Microbiologist Elli Theel, who directs the Infectious Diseases Serology Laboratory at Mayo Clinic, calls the 2015 study incredibly promising. The sensitivity they showed just in early Lyme disease patients was very high, the highest Ive actually seen, she said.

In an upcoming publication, the researchers also showed that metabolomics can differentiate Lyme from a similar tick-borne disease called southern tick-associated rash illness . The disease causes similar symptoms as Lyme, including a bullseye rash, and occurs in overlapping geographic regions. Currently there is no laboratory test to diagnose STARI, and little is known about how the disease progresses and how to treat it, something Molins hopes will change with better testing.

What Do My Test Results Mean

If both tests come back positive, that means you have had Lyme disease at some point in time.

If either or both of your tests come back negative, your doctor may still diagnose Lyme disease, particularly if you recently developed Lyme-like symptoms, regardless of your test results. But, if your doctor does not diagnose you with Lyme disease, you can ask to be re-tested in a few weeks. If you do have Lyme disease, your body may build up sufficient antibodies by that point to be detected by a blood test.

Two-step blood testing for later stages of Lyme disease is more accurate than for early infection because your body should have had sufficient time to produce the antibodies detected by diagnostic tests.

Interpreting the Western blot test

The Western blot test looks at whether you have an immune response the production of IgM or IgG antibodies to specific proteins on the Lyme disease bacteria. IgM antibodies are usually made by your body when the infection is new and recent, while IgG antibodies are usually made some weeks later. When the IgM or IgG antibodies combine with specific proteins from the Lyme disease bacteria, this produces dark spots, or bands on the Western blot test strip.

The CDC considers a Western blot test to be positive for Lyme disease if at least two of three IgM bands are positive within 30 days of symptom onset, or five of 10 IgG bands are positive at any time.

If your Western blot test comes back negative, ask your doctor:

Can I Be Assured That The Type Of Lyme Disease Testing Carried Out In Ireland Is Accurate

Yes. Irish laboratories operate to a very high standard of quality. Laboratories in Ireland follow the testing guidelines of the US Centres for Disease Control and prevention , Infectious Disease Society of America , European Federation of Neurological Societies and British Infection Association . These guidelines provide information on which of the currently available laboratory tests have enough evidence to accurately diagnose Lyme disease.

It is important that patients who are concerned about Lyme disease seek help and receive a firm diagnosis in Ireland to ensure continued medical care. It is important to ensure that your symptoms and lab results are considered together to make sure your diagnosis is as correct as possible.

Is There A Lyme Disease Test Kit

Blood collection kits are available for at-home Lyme disease testing. Lyme disease test kits can cost as less as $20 and as much as $100 or more. Using a Lyme disease test kit is as simple as pricking your finger and smearing or collecting the blood onto the kit for testing.

However, testing for Lyme disease in a more controlled environment such as a lab or clinic is preferable as qualified healthcare professionals are likely to perform a more reliable test.

    When A Lyme Diagnosis Is Simple

    A person who notices a tick bite and gets a bullseye rash will typically get a Lyme disease diagnosis. Treatment can start right away without any testing.

    Another straightforward example would be a person who has spent time outdoors in an area where Lyme disease is common. Lets say that person doesnt have a bullseye rash but has other possible symptoms of Lyme disease. Their doctor does a standard two-step blood test, and both are positive. In this case the person gets a Lyme disease diagnosis and starts treatment.

    Who Gets Lyme Disease

    Lyme Disease Prognosis – Johns Hopkins – (5 of 5)

    Anyone bitten by an infected deer tick can get Lyme disease. Most U.S. cases of Lyme disease happen in Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, and Wisconsin. But Lyme disease is also found in other parts of the U.S., Europe, and Asia.

    Other things that might increase a person’s risk include:

    • spending a lot of time outdoors in tall grass, brush, shrubs, or wooded areas
    • having pets that may carry ticks indoors
    • activities such as yardwork, hiking, camping, fishing, or hunting in tick-infested areas

    Other Diagnostic Tests For Lyme Disease

    Some laboratories offer Lyme disease testing using urine or other body fluids. These tests are not approved by FDA because they have not been proven to be accurate. For example, one study of urine-based polymerase chain reaction assays for Lyme disease diagnosis showed that with currently available tools, urine cannot be used to accurately diagnose Lyme disease. Another study by NIAID-supported scientists showed that the Lyme Urinary Antigen Test was unreliable and resulted in excessive numbers of false positives. In the same study, researchers confirmed that an ELISA followed by a Western blot test was nearly 100 percent reliable in diagnosing Lyme disease. With the availability of so many Lyme disease tests, including non-commercial tests developed by individual facilities, it is impossible to address the accuracy of each one. The development of new, rapid, clearly validated diagnostic tests continues to be a need.

    Why Do I Need A Lyme Disease Test

    You may need a test if you have symptoms of infection and were exposed or possibly exposed to ticks that carry the bacteria that causes Lyme disease. The first symptoms of Lyme disease usually show up between 3 and 30 days after the tick bite.

    Early signs and symptoms may include:

    • A reddish round skin rash that slowly gets bigger over several days. It usually doesn’t itch or hurt, but it may be warm. As it gets better, it may look like a bull’s-eye , but not always.
    • Muscle and joint aches
    • Swollen lymph nodes

    Later signs and symptoms of Lyme disease usually affect your joints and nervous system. They include:
