Which B Burgdorferi Antigens Are Used And How Is The Test Interpreted
The Equine Lyme Multiplex assay is based on three antigens, called outer surface proteins , of B. burgdorferi. Various research studies have shown that Osp antigen expression changes on the bacterial surface in response to tick feeding and again after infection of a warm-blooded host, such as dogs, horses, or humans . In response to infection, horses develop antibodies to these Osp proteins and testing for antibodies to specific Osp antigens can assist in the diagnosis of infection and Lyme disease.
What We Look For In The Best Lyme Disease Tests
There are a few important criteria we look for when choosing a test for Lyme disease. Some may be of higher priority to you than others, but all are worth considering while you decide.
- Trustworthiness: Does the company have positive reviews from real customers. Do they test your samples in accredited labs?
- Value-for-money: Does the Lyme disease cost come at a fair price with no pricey add-ons?
- Actionability: Does your report guide you towards the next steps following a positive result? Is experienced medical advice available?
- Speedy Results: Are your results delivered in a timely manner so you can take any required action as soon as possible?
- Report Clarity: Can you understand your results? Is support available if you require further explanation?
- IgG and IgM antibody test for Lyme disease bacteria
- CLIA and Cap-accredited labs
The Lyme disease test from LetsGetChecked analyzes your blood sample for reactivity to Borrelia IgG and IgM antibodies Borrelia is the bacteria carried by some ticks, that causes Lyme disease. A large concentration of IgM can indicate recent infection, while a higher concentration of IgG may indicate a Lyme disease infection thats been present for a while.
If you test positive, a member of the nursing team will call you to discuss your results and treatment options. If you need any additional support, the nursing team is available 24/7 to answer any questions that may have slipped your mind during your consultation.
How To Remove A Tick
Removing a tick is the same for humans and animals. Its important you do not crush or damage the tick because it could cause Lyme bacteria to pass from the tick into your bloodstream.

New Test Can Detect Lyme Disease Soon After Infection
Press release from the National Institute of Standards and Technology , Feb. 12, 2016:
When it comes to early diagnosis of Lyme disease, the insidious tick-borne illness that afflicts about 300,000 Americans annually, finding the proverbial needle in the haystack might be a far easier challengeuntil now, perhaps. An experimental method developed by federal and university researchers appears capable of detecting the stealthy culprit Lyme bacteria at the earliest time of infection, when currently available tests are often still negative.
The team suggests the approach might also be useful for early detection of other elusive bacterial infections. The collaboratorsfrom the National Institute of Standards and Technology , Institute for Bioscience and Biotechnology Research, and Johns Hopkins School of Medicinerecently reported the successful first trial of their new method.
Our hypothesis was that Lyme bacteria shed vesicle-like particlesor fragmentsderived from the cell wall of the bacteria circulating in the serum of individuals. These particles would contain membrane proteins that can be detected to provide a unique indicator of infection, explains NIST research chemist Larik Turko.
In one patient, the experimental method detected the bacteria three weeks before infection was confirmed with the standard blood tests now used. For the other two, infection was detected simultaneously by the two methods.
Access To Lyme Disease Testing Services
This guidance on the laboratory diagnosis of Lyme disease is intended for healthcare professionals in the UK. Patients concerned about possible Lyme infection should consult an appropriate healthcare professional, for example their GP, in the first instance.
Health professionals wishing to discuss a possible case or ascertain local arrangements for testing should contact a local Infection specialist .
NHS testing for Lyme disease is available through local service providers and the Rare and Imported Pathogens Laboratory at PHE Porton where ISO15189 accredited confirmatory testing is also provided. RIPL is also introducing a testing service for neurological Lyme disease.
RIPL provides medical and laboratory specialist services to the NHS and other healthcare providers, covering advice and diagnosis of a wide range of unusual bacterial and viral infections, including Lyme disease.
RIPL continuously updates its methods and will make further information on Lyme disease diagnostic testing available as it arises.

Interpretation Of Lyme Multiplex Results1213
The Lyme Multiplex Assay is a fully quantitative test. It results in a numeric antibody value for each of the three B. burgdorferi antigens tested. A brief interpretation on each value is submitted with the test report. In addition, the antibody profile gives an advanced interpretation on the infection and vaccination status of the horse. Antibodies to OspA serve as markers for vaccination and those to OspC and OspF as markers for infection . In treated horses, quantitative antibody values are valuable indicators to follow-up on treatment success.

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.
The Chance Of Getting Lyme Disease
Not all ticks in England carry the bacteria that causes Lyme disease.
But it’s still important to be aware of ticks and to safely remove them as soon as possible, just in case.
Ticks that may cause Lyme disease are found all over the UK, but high-risk places include grassy and wooded areas in southern and northern England and the Scottish Highlands.
Ticks are tiny spider-like creatures that live in woods, areas with long grass, and sometimes in urban parks and gardens. They’re found all over the UK.
Ticks do not jump or fly. They attach to the skin of animals or humans that brush past them.
Once a tick bites into the skin, it feeds on blood for a few days before dropping off.

What To Know About Seeing A Doctor And Getting Tested
Whatever kind of doctor you see, they will consider your medical history, your symptoms, and your Lyme disease test results when making a diagnosis. They should perform what is known as a differential diagnosis in order to rule out common misdiagnoses, such as Rheumatoid Arthritis, Chronic Fatigue Syndrome, ALS, MS, etc.
Many doctors rely on the two-tier system recommended by the Centers for Disease Control and Prevention, which consists of the following two blood tests:
- Western blot test
However, research shows that these tests are severely limited in accuracy and sensitivity. A LLMD may be able to help you get tested with newer and more accurate testing technology.
Lyme disease recovery starts with finding a doctor who has sufficient experience with Lyme as well as access to the right diagnostic testing. To learn more about what tests are available for Lyme disease today, including IGeneXs ImmunoBlot test, check out the blog The Best Test for Lyme Disease.
You Should Take The Test If:
- You are presenting with symptoms of Lyme disease
- You live in a place that is rich in vegetation or a woodland area
- You live in Northern America or Northern Europe
- You go camping or hiking on a regular basis, particularly during the Summer or Autumn
- You come into contact with larger woodland animals on a regular basis
The sample must be collected before 10am on a Monday, Tuesday, Wednesday or Thursday and returned on the same day.
Fasting means that you take the test in the morning before you have breakfast. You can still drink water when fasting. Always follow the advice of your physician with regards to fasting, particularly if you have any medical conditions.

Lyme Disease Frequently Asked Questions
If you have not done so already, remove the tick with fine-tipped tweezers.
The chances that you might get Lyme disease from a single tick bite depend on the type of tick, where you acquired it, and how long it was attached to you. Many types of ticks bite people in the U.S., but only blacklegged ticks transmit the bacteria that cause Lyme disease. Furthermore, only blacklegged ticks in the highly endemic areas of the northeastern and north central U.S. are commonly infected. Finally, blacklegged ticks need to be attached for at least 24 hours before they can transmit Lyme disease. This is why its so important to remove them promptly and to check your body daily for ticks if you live in an endemic area.
If you develop illness within a few weeks of a tick bite, see your health care provider right away. Common symptoms of Lyme disease include a rash, fever, body aches, facial paralysis, and arthritis. Ticks can also transmit other diseases, so its important to be alert for any illness that follows a tick bite.

There are no reports of Lyme disease being spread to infants through breast milk. If you are diagnosed with Lyme disease and are also breastfeeding, make sure that your doctor knows this so that he or she can prescribe an antibiotic thats safe for use when breastfeeding.
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.

Advantages Of The Equine Lyme Multiplex Assay
The Equine Lyme Multiplex Assay is available only at the Animal Health Diagnostic Center at Cornell University. It combines the results obtained by previous ELISA and Western blot testing and exceeds the information obtained by tests that are based on a single antigen of B. burgdorferi such as C6. The Lyme Multiplex Assay provides information whether the horse got infected with B. burgdorferi and when the infection occurred. The test results are fully quantitative and appropriate to follow-up on treatment success or response to vaccination. The advantages of the Lyme Multiplex Assay compared to other Lyme tests are:
The Lyme Multiplex Assay result provides advanced information beyond any of the currently available Lyme disease testing methods. Lyme Multiplex Assay testing allows a better definition of the horses current infection status and assists in determining treatment options and prognosis. The infection status can also be determined most vaccinated horses. Interpretation varies slightly depending on the vaccine used.
Key Points To Remember
- Most Lyme disease tests are designed to detect antibodies made by the body in response to infection.
- Antibodies can take several weeks to develop, so patients may test negative if infected only recently.
- Antibodies normally persist in the blood for months or even years after the infection is gone therefore, the test cannot be used to determine cure.
- Infection with other diseases, including some tickborne diseases, or some viral, bacterial, or autoimmune diseases, can result in false positive test results.
- Some tests give results for two types of antibody, IgM and IgG. Positive IgM results should be disregarded if the patient has been ill for more than 30 days.

Lyme disease is the most common vector-borne disease in the United States. Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii.It is transmitted to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread.
Lyme disease, also known as Lyme borreliosis, is a vector-borne disease caused by the Borrelia bacterium which is spread by ticks in the genus Ixodes. The most common sign of infection is an expanding red rash, known as erythema migrans, that appears at the site of the tick bite about a week after it occurred. The rash is typically neither itchy nor painful.
For over 30 years, IGeneX has been the global leader in the research and development of tests that accurately detect Lyme disease, Relapsing Fever, and other tick-borne diseases. Tick-borne illnesses can affect every part of your life, and without effective diagnosis and treatment, symptoms can often worsen and progress into severe and even .
