The Igenex Lyme Immunoblot Solves These Problems

How Long Does Lyme Disease Last

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.

Traditional Lyme Disease Tests Are Not Specific Enough

Lyme disease is caused by the spiral-shaped bacteria Borrelia. There are multiple species and strains of Lyme borreliae . Therefore, tests must be targeted to these multiple species and strains in order to be able to detect them. If a patient is infected with a species or strain of Lyme borreliae that their test cant detect, they will get a false-negative test result and thus risk missing their diagnosis. This can be costly and dangerous.

Many ELISA and Western blot Lyme disease tests are only equipped to detect one strain of one species of Borrelia: Borrelia burgdorferi B31 . This means that those tests are missing infections caused by other strains and/or species of Lyme borreliae.

In one internal study designed to test the validity of the IGeneX ImmunoBlot against traditional Western blot tests, a total of 132 patients were tested by both Lyme Western blots and Lyme IB. 43 patients were seropositive on the ImmunoBlot, and 14 were positive on standard Western blots prepared from a mixture of two species for Bb ss B31 and 297. Thus 29 of the 43 patients tested negative on Western blots i.e., the Western blot totally missed their infections with strains other than Bb ss B31 and 297.

With such limited tests, patients infected with non-B31 species and strains e.g., B. mayonii, B. californiensis, or European species are at risk of receiving false negatives and missing the chance to treat their diseases.

Sample Types For Lyme Disease Testing

For routine Lyme disease serological testing, you must send a serum sample .

For testing for neurological Lyme disease, you must send paired CSF and serum samples taken on the same day. If possible, please provide CSF cell count and total albumin, IgG and IgM values. If albumin, IgG and IgM measurements are not available, RIPL will make arrangements for these measurements at additional cost.

PCR testing is available. We recommend that specialists call RIPL to discuss appropriate sample types for PCR. These may include joint fluid, biopsy tissue, CSF and EDTA plasma. Please submit biopsies as fresh tissue in a sterile container, ideally with a drop of sterile saline to prevent the tissue drying out.

What If Your Lyme Disease Test Is Positive

Its important to note that a positive result doesnt mean you have a diagnosis of Lyme disease. The tests will show that antibodies are present in your blood, but a physician will need to order another type of test before you get an official diagnosis.

If someone gets a positive at-home test, definitely see your doctor, says Dr. Puja Uppal, a board certified family medicine physician and the chief medical officer at Think Healthy.

A physician will likely order both an enzyme-linked immunosorbent assay and a Western blot test, which check for antibodies specific to Borrelia burgdorferi. They will consider the results of both these tests, along with your symptoms, to make an accurate diagnosis.

Is It Possible For Lyme Disease To Be Misdiagnosed As Amyotrophic Lateral Sclerosis Are There Similarities In Symptoms Between These Two Diseases

It

The question of a relationship between Lyme Disease and ALS first received significant academic attention when Dr. John Halperin who was then a neurologist at Stony Brook conducted a study in which he compared the frequency of blood test positivity to the agent of Lyme disease among patients with ALS to community controls. The results indicated a higher percentage of the ALS patients were seropositive for Lyme Disease. Since then, there have been isolated case reports both in the media and one or two in the academic literature indicating that a patient had been misdiagnosed with an ALS-like illness only later to be re-diagnosed and treated for Lyme disease with good clinical response. Although we suspect that there may be rare individuals who have symptoms similar to ALS but actually have proximal motor neuropathy caused by Lyme disease, the vast majority of patients with ALS are not thought to have Lyme disease as the cause of their serious disease. Clinical trials have been underway using antibiotics for ALS not because there is belief that ALS is caused by a microbe but because these antimicrobial agents have other properties as well, such as decreasing inflammation or decreasing glutamatergic excitotoxicity. The studies examining intravenous ceftriaxone as a treatment for ALS were not successful.

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.

At What Point Do I Stop Antibiotics For The Psychological Symptoms Of Lyme Disease And Conclude That These Symptoms Will Not Go Away

The cause of the psychological symptoms in Lyme disease is unclear. It is clear that patients with acute Lyme disease who develop new onset depressive symptoms or irritability or cognitive disturbances often show a remarkable improvement when given antibiotic therapy. If the psychological symptoms persist or if the initial symptoms are severe, it is very important to consult with a psychiatrist to evaluate how best to treat these symptoms apart from the antibiotic therapy. When symptoms continue even after a repeated course of antibiotic therapy, this could be due to the fact that an activated immune system results in a change in neurotransmitter functioning. As a result, the altered neurotransmitter function may contribute to ongoing depressive symptoms, even after the immune system is no longer activated. Treatment of the psychiatric symptoms at that point would require anti-depressant or anti-anxiety medications or psychotherapy.

Review – Lets get Checked – Lyme Disease at Home Test Kit

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.

Symptoms Of Lyme Disease

A circular or oval shape rash around a tick bite can be an early symptom of Lyme disease in some people.

The rash can appear up to 3 months after being bitten by an infected tick, but usually appears within 1 to 4 weeks. It can last for several weeks.

The rash can have a darker or lighter area in the centre and might gradually spread. It’s not usually hot or itchy.

The rash may be flat, or slightly raised, and look pink, red, or purple when it appears on white skin. It can be harder to see the rash on brown and black skin and it may look like a bruise.

Some people also get flu-like symptoms a few days or weeks after they were bitten by an infected tick, such as:

  • a high temperature, or feeling hot and shivery
  • headache
  • tiredness and loss of energy

Some people with Lyme disease develop more severe symptoms months or years later.

This is more likely if treatment is delayed.

These more severe symptoms may include:

  • pain and swelling in joints
  • nerve problems such as pain or numbness
  • heart problems
  • trouble with memory or concentration

Medical And Diagnostic Applications

Prospective parents can be tested for being genetic carriers, or their children might be tested for actually being affected by a disease. DNA samples for prenatal testing can be obtained by amniocentesis, chorionic villus sampling, or even by the analysis of rare fetal cells circulating in the mother’s bloodstream. PCR analysis is also essential to preimplantation genetic diagnosis, where individual cells of a developing embryo are tested for mutations.

  • PCR can also be used as part of a sensitive test for tissue typing, vital to organ transplantation. As of 2008, there is even a proposal to replace the traditional antibody-based tests for blood type with PCR-based tests.
  • Many forms of cancer involve alterations to oncogenes. By using PCR-based tests to study these mutations, therapy regimens can sometimes be individually customized to a patient. PCR permits early diagnosis of malignant diseases such as leukemia and lymphomas, which is currently the highest-developed in cancer research and is already being used routinely. PCR assays can be performed directly on genomic DNA samples to detect translocation-specific malignant cells at a sensitivity that is at least 10,000 fold higher than that of other methods. PCR is very useful in the medical field since it allows for the isolation and amplification of tumor suppressors. Quantitative PCR for example, can be used to quantify and analyze single cells, as well as recognize DNA, mRNA and protein confirmations and combinations.

Getting An Initial Screening

  • 1Discuss your symptoms with your doctor. When you talk to your doctor, let them know exactly what symptoms you’ve been experiencing and for how long. Let your doctor know the date you were bitten, and how long after the bite each symptom occurred.XTrustworthy SourceAmerican Academy of Family PhysiciansOrganization devoted to improving the health of patients, families, and communitiesGo to source
  • There are many varied symptoms of Lyme disease, and each patient may not get all of them. Describe any differences in your mental or physical condition since you were bitten by the tick, even if you don’t think the difference is related.
  • Even if you’ve experienced no symptoms, it’s still possible that you’ve contracted Lyme disease. Don’t be afraid to insist on an initial screening to rule it out if it’s something that worries you.
  • 2Have a blood sample taken. The standard initial screening test is an enzyme-linked immunoassay blood test. It measures antibodies produced by your immune system to combat harmful substances. This test is similar to blood tests you would take to identify allergies.XTrustworthy SourceMedlinePlusCollection of medical information sourced from the US National Library of MedicineGo to source
  • Your blood sample will be sent to a laboratory and the blood will be introduced to a testing solution. If the antibodies produced to fight Lyme disease are present, the solution will change color.
  • When Not To Take This Lyme Disease Test

    Health Care Providers

    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.

    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.

    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.

    Can Autism Be Misdiagnosed As Lyme Disease What Research Is There To Prove This Can A Child With Autism Be Successfully Treated For Lyme Disease

    It would be extremely unusual to misdiagnose a child with autism as having Lyme disease. Lyme disease typically gets diagnosed when a child has joint and muscle pains, along with fatigue, positive blood tests, and central or peripheral nervous system involvement. Certainly a child with autism may also get Lyme disease and thus have two disorders. In that situation, treatment of Lyme disease should result in a resolution of the Lyme disease but it would not likely result in a change in the autism symptoms. The question of interest to us is whether there are cases of “regressive autism” that occur in older pre-school age children for example that has been induced by a central nervous system infection, such as with Borrelia burgdorferi. In such a situation, treatment with antibiotics may well result in an improvement in the developmental regression. This area however has not been adequately studied.
