Once ordered, an at-home Lyme disease test kit is delivered to your home, where you can collect the sample privately and comfortably. The kit will include the instructions, the sample collector, and the box to return the sample.

Once the results are ready, you will receive them in your email or through the company’s online portal, or they will be sent to your doctors office.

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.

Where Is Lyme Disease Found

In the United States, Lyme disease has been reported in every state, but over 95% of cases are from the Northeastern, Mid-Atlantic, and upper Midwestern states, with a small number of cases reported along the West Coast, especially Northern California. In Canada, Lyme-positive dogs are found mostly in southern Ontario and southern Manitoba, with a small number of cases in southern Quebec and the Maritime provinces.

When Should I Get Checked For Lyme Disease

Generally, it is best to get tested for Lyme disease if you live where ticks are common or have recently visited such areas. Most certainly, you should get tested if you suspect that a tick has bitten you. It is important to talk to your doctor if you think you have any of the following early Lyme disease symptoms:

  • A rash resembling a bulls eye on the spot where youve been bitten
  • Fatigue
  • Headaches
  • Fever

Other symptoms dont show up immediately. Sometimes, it takes up to a few weeks or months after the tick bite to notice the following:

  • Swelling on the joints or severe joint pain
  • Tingling in the feet and hands
  • Dizziness
  • Shortness of breath

While it is okay get checked early, Lyme disease test results numbers are more authentic a few weeks after youve been bitten by a carrier-tick. Your body would have developed antibodies within that period, and that can make it easier to detect the disease.

Is Treatment 100% Effective

Lyme Disease

Scientists are divided on this topic. Some studies suggest that that even long-term antibiotics may not completely clear infection dogs may get sick again at some point after antibiotic treatment is stopped. Other studies suggest that complete clearance of infection is possible with antibiotic treatment. Further research is required to answer this question.

Completion Of Lyme Disease Test Request Form

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.

Investigation Of Suspected Neurological Lyme Disease

The diagnosis of neurological Lyme disease can only be confirmed by examination of the CSF and a paired serum. A definite diagnosis is based on the presence of a pleocytosis in the CSF, demonstration of intrathecal synthesis of specific antibodies to Borrelia species in CSF by comparison to serum and the presence of neurological symptoms. It is not possible to confirm intrathecal synthesis and hence definite neurological Lyme disease without a paired serum .

In 2018 RIPL is introducing a service for the detection of intrathecal synthesis of Borrelia-specific antibodies which is summarised in this flow diagram.

Clinicians may ask for guidance on laboratory testing of CSF from RIPL if required.

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.

Lyme Disease Is Remarkably Difficult To Diagnose

Officials harvest ticks, test for Lyme disease in Sacramento area

The problem with Lyme disease is that the bacteria can create a hard shell around themselves when inactive so that the blood tests are unable to detect them. This is especially true when the disease has reached the chronic stage. The timing of the symptoms is often used by a medical provider to establish a time line to a tick bite or exposure to a high-risk region where the disease is commonly transmitted.

Because the ticks that can spread Lyme disease are often the size of a pinhead, the ticks might not even be notice. A bulls-eye rash at the bite location is a trademark symptom of Lyme disease, but only about half of the people who are infected with the bacteria develop the rash. Once the disease reaches the chronic stage, chronic arthritis, joint pain, and neurological symptoms begin to appear, sometimes several months after the infection.

Is Lyme Disease Curable

While there is no vaccine to prevent us from getting Lyme disease, it can be treated with antibiotics, and most people recover within a few weeks. However, some people can get what is known as Post-Treatment Lyme Disease Syndrome, in which symptoms such as pain, fatigue, or difficulty thinking can last for months.

Negative C6 Elisa On Serum

Early clinical Lyme disease in the form of erythema migrans with associated history of a tick bite should be treated empirically. There is no need for testing unless there are further symptoms.

A negative ELISA result in the early stages of Lyme disease does not exclude infection. If acute Lyme disease is suspected but serology results are negative, we recommend that the test is repeated in 4-6 weeks with a fresh sample to look for seroconversion.

In patients with long term symptoms a negative ELISA test usually excludes Lyme disease as a cause of these symptoms. Information on differential diagnosis for patients with persistent symptoms and negative Lyme disease serology results is available.

Should You Get Tested For Lyme Disease

The current laboratory diagnostic tests for Lyme disease are blood tests to detect the antibodies created by your body to fight and kill the bacteria that causes Lyme. This bacteria is called Borrelia burgdorferi, or Bb.

However, with early-stage Lyme your antibodies may not have had time to develop in your body. Therefore a blood test at this time will often appear negative. It can take your body up to two months to develop enough antibodies to be detected by these tests. In other words you could have Lyme but the test results will still come up negative.

What does this mean for you? By all means, if your doctor recommends a test, get the test. But dont rely on it completely. Trust your body and trust your homework. Monitor your symptoms. Ask questions.

Other Lyme Disease Tests

Test A Tick For Lyme Disease

Three other tests that may be used to diagnose Lyme disease are polymerase chain reaction , antigen detection and culture testing. They are called direct tests because they detect the bacteria, not just your immune response to it.

PCR multiplies a key portion of DNA from the Lyme bacteria so that it can be detected. While PCR is highly accurate when the Lyme DNA is detected, it produces many false negatives. This is because the Lyme bacteria are sparse and may not be in the sample tested.

Antigen detection tests look for a unique Lyme protein in fluid . Sometimes people whose indirect tests are negative are positive on this test.

Culture is the gold standard test for identifying bacteria. The lab takes a sample of blood or other fluid from the patient and attempts to grow Lyme spirochetes in a special medium.

Although culture tests are generally accepted as proof of infection, the CDC has advised caution on the only commercially available culture test developed by Advanced Laboratory Services. LDo recognizes that the test is new and requires further validation in other studies. However, we believe that informed patients should be able to choose the test if they prefer. Choice is particularly important given the low quality of Lyme disease tests generally.

Special Considerations For Vaccinated Horses

An approved Lyme vaccine for horses is currently not available. Horses are sometimes vaccinated with one of the three available Lyme vaccines for dogs for attempted protection of horses that are housed in Lyme endemic areas. Efficacy studies of canine vaccines in horses are not yet available, but experimental data suggested that anti-OspA antibodies are protective in horses.

All available vaccines contain OspA antigen as the sole or one of the vaccine components. Antibodies to OspA are identified by the Equine Lyme Multiplex Assay to determine the vaccination status in vaccinated horses. To provide our clients with the best interpretation for each animal, we need information on the vaccine used. This includes the name of the vaccine and the date when the horse was last vaccinated. Please include this information on the submission form when samples of vaccinated horses are submitted for testing.

Recent studies indicate that horses can respond to the canine vaccines, but the responses are typically short-lived17,18. It is therefore recommended to vaccinate horses in close proximity to tick season, approximately four weeks before ticks are typically abundant in the area. Additionally, confirmatory testing is recommended after vaccination of horses since low OspA antibody responses have been observed in individual horses.

Late Lyme Disease Symptoms

  • Have you had any of the following symptoms typical of late or chronic Lyme disease?
  • Fatigue
  • Psychiatric
  • Yes
  • No
  • Unsure
  • New onset fatigue, widespread pain, sleep disturbance, and cognitive impairment are common symptoms of late Lyme disease. Many symptoms of late or chronic Lyme disease are non-specific and common among diseases. What sets Lyme patients apart is the severity of symptoms and the degree of functional impairment. Patients report pain at the severity of post-operative patients, fatigue at the level of patients with multiple sclerosis, and functional impairment comparable to those with congestive heart failure. Most patients with chronic Lyme disease report one or more of the following symptoms as severe or very severe: fatigue , sleep impairment , joint pain , muscle aches , other pain , depression , cognitive impairment , neuropathy , headaches and heart-related issues . Chronic Lyme patients generally report more than one symptom and average three severe or very severe symptoms.
  • The Igenex Lyme Immunoblot Solves These Problems

    How To Test For Lyme Disease

    IGeneX has developed a serological test that increases specificity without sacrificing sensitivity that has changed how to test for Lyme disease. It uses specifically created recombinant proteins from multiple species and strains of Lyme borreliae and reduces inconsistencies in reading and interpreting the test bands.

    More species detected The Lyme ImmunoBlot tests for more species of Lyme borreliae than the traditional ELISA and Western blot tests, reducing the risks of false negatives due to the inability to detect antibodies to a certain strain or species of Lb. The test includes all Borrelia-specific antigens relevant in North America and Europe, not just B. burgdorferi B31 or 297.

    The result is a single test that replaces at least 8 Western blots.

    More accurate testing The ImmunoBlot uses specific recombinant proteins that are sprayed in precise amounts onto specific locations on the membrane strip, allowing for greater control of the quantity and location of the antigens. This makes reading the bands much more accurate and consistent.

    Earlier detection The ImmunoBlot can detect infections at multiple stages of illness, letting you catch infections earlier.

    The IgM and IgG ImmunoBlots superior specificity and sensitivity make them the best Lyme disease test available.

    What Abnormal Results Mean

    A positive ELISA result is abnormal. This means antibodies were seen in your blood sample. But, this does not confirm a diagnosis of Lyme disease. A positive ELISA result must be followed up with a Western blot test. Only a positive Western blot test can confirm the diagnosis of Lyme disease.

    For many people, the ELISA test remains positive, even after they have been treated for Lyme disease and no longer have symptoms.

    A positive ELISA test may also occur with certain diseases not related to Lyme disease, such as rheumatoid arthritis.

    Borrelia Species Pcr Results

    Borrelia species DNA may occasionally be detected in the blood by PCR, but a negative PCR test is of no value in excluding localised Lyme disease.

    The overall sensitivity of PCR on a skin biopsy of an EM or ACA rash is around 50% and is limited by the chance of a single biopsy hitting a site with a significant number of organisms.

    In neurological Lyme disease involving the CNS, up to 10% of cases may be PCR positive on a CSF sample a negative PCR result does not exclude the diagnosis.

    Synovial fluid may be positive by PCR in up to 50% of cases. A negative result does not exclude the diagnosis.

    Alternative Diagnostic Tests Not Available At Ripl

    Tests used in the NHS and PHE to identify Lyme disease are well characterised, standardised, and are highly reproducible between laboratories. They are the methods of choice recommended in the 2018 NICE Lyme disease guideline, following an extensive review of the evidence and literature. International external quality assurance schemes are in place to ensure consistency between different centres offering these tests.

    Several private laboratories in Europe and the USA offer an alternative type of test called an ELISpot to diagnose Lyme disease. This looks for different markers in blood samples compared to conventional validated Lyme disease serology tests. The laboratories using these tests in the diagnosis of Lyme disease do not publish their methods, and have not produced any peer reviewed publications on their clinical value.

    This makes it very difficult to verify their results, especially as there are no national or international EQA schemes for Lyme disease ELISpot tests and therefore no independent verification of performance between laboratories. Without independent evidence it is impossible to determine the validity of results produced using these alternative tests.

    RIPL cannot interpret the results of alternative diagnostic tests.

    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.
