Officials harvest ticks, test for Lyme disease in Sacramento area

MDPH does not offer tick identification or tick testing. While testing ticks can provide useful information, there are some notable issues:

  • Positive or negative results from a tick or ticks attached to a person do not provide definitive evidence that that you were exposed or not exposed
  • Most people diagnosed with a tick-borne disease are not aware that they have been bitten by a tick and the tick you do find may not be the only tick that bit you
  • It is possible to be bitten by a tick carrying a disease and not be infected with that disease, depending on many factors, including how long the tick was attached to you

If you choose to have a tick tested, it is important to keep in mind the following:

  • Tick testing does provide general information about risk to individuals and populations exposed to ticks in particular geographic areas. The University of Massachusetts Laboratory Of Medical Zoology makes their test results available to the public, free of charge, through the Tick-Borne Disease Network Passive Surveillance Database. The name and address of individuals that send ticks in is always kept confidential, but the information about where the tick was found and what pathogens it carried is of great value to the public and agencies trying to track tick-borne diseases.
  • Can A Tick Be Tested For Lyme Disease

    Researchers examined the prevalence of ticks in the Quebec region, along with the frequency of engorged ticks carrying Borrelia burgdorferi , the causative agent of Lyme disease. Their findings suggest that tick testing may not always be an effective tool in determining the risk of infection.

    Ticks can be tested for the Lyme disease bacteria and other tick-borne pathogens. But the accuracy of test results may depend on a ticks lifecycle stage.

    A study by Gasmi et al. found that results may not be accurate when testing ticks which are engorged. The authors examined 4,596 I. scapularis ticks removed from individuals living in Quebec.

    They found that 24.9% of the non-engorged blacklegged tickswere infected with Borrelia burgdorferi , the causative agent of Lyme disease.

    Engorged ticks were expected to have an even higher rate of infection with the Lyme disease bacteria. But the prevalence was much lower with only 8.9% of engorged ticks testing positive for the Lyme disease agent. These findings are consistent with those from another Canadian study.

    Engorged ticks were expected to have an even higher rate of infection with the Lyme disease bacteria. But the prevalence was much lower.

    It is still unclear why testing of engorged ticks is not accurately revealing the higher prevalence of Bb infection. The authors suggest that it could be due to the presence of inhibitors in the blood meal or problems with the collection and transportation of engorged ticks.

    What Are The 3 Stages Of Lyme Disease

    Although Lyme disease is commonly divided into three stages early localized, early disseminated, and late disseminated symptoms can overlap. Some people will also present in a later stage of disease without having symptoms of earlier disease.

    Are There Any Risks To Lyme Disease Tests

    Test for tick

    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.

    Diagnosis Of Lyme Disease

    The diagnosis of Lyme disease can be made clinically or in conjunction with laboratory test results. When the skin rash is typical and when a patient has been exposed to an environment where blacklegged ticks are known to be established, the diagnosis can be made on clinical grounds alone. In parts of Canada where adventitious, unestablished populations of blacklegged or western blacklegged ticks have been noted, a clinical diagnosis is more challenging. When the rash is atypical or occurs in circumstances in which exposure to the appropriate vector tick species was unlikely, diagnosis is based on the demonstration of a serological response to B burgdorferi. Immunoglobulin M antibodies are usually detectable within weeks of the onset of symptoms however, a significant proportion of patients with EM may not have detectable antibody at the time of initial presentation . Furthermore, when patients are treated very early in the course of illness, antibodies may not develop. When an initial antibody determination is negative, it is suggested that a second serum specimen be collected four weeks later.

    Current evidence suggests that commercially available enzyme immunoassays used for the purpose of screening are sufficiently sensitive .

    Antigen detection has also been used in both spinal fluid and urine. As with NAT, antigen tests cannot be recommended unless their sensitivity and specificity significantly improve .

    Should You Get A Test For Lyme Disease

    If Lyme disease is treated soon after a tick bite, the outlook is great. Most cases of Lyme disease respond to a 2- to 4-week round of antibiotics.

    If Lyme disease goes untreated, it can be more difficult to eliminate. For some, it can lead to inflammation of the joints, heart, and nervous system. Progression of the disease, and its severity, can vary from person to person.

    Lyme disease is staged in categories: acute, early disseminated, and late disseminated. Later stages of Lyme disease may involve multiple systems in the body.

    The most common sign of Lyme disease is an erythema migrans, or bulls-eye rash. The rash often appears after a delay of 3 to 30 days after the tick bite, according to the

    Research from 2014 suggests that the bulls-eye rash may last for 3 to 4 weeks. About 80 percent of people with Lyme disease have a single erythema migrans rash. But the bacteria can spread and lead to multiple rashes, indicating disseminated Lyme disease.

    While a rash is the most common symptom of Lyme disease, it isnt the only one.

    With disseminated Lyme disease, symptoms can also include neurologic conditions, such as cranial nerve palsy and meningitis that mimics aseptic meningitis. Heart inflammation can also be a sign of Lyme disease.

    If youre experiencing any of these signs or symptoms, an at-home test may help you identify Lyme disease. With the click of a button, a test can be shipped to your front door.

    To select the best tests, we look at studies and user reviews.

    What Are The Limitations To Testing Ticks For Diseases

    Ticks & Lyme Disease: People not waiting for symptoms to get tested
    • If a tick tests positive for an infection, it does not mean that the tick passed the infection to the person it fed on.
    • If a tick tests negative for infection, it does not mean that the person it fed on will not get sick. The test may be wrong or there may be another tick that was not found.
    • Clinical decisions should not wait until tick results are available.

    Other Lyme Disease Tests

    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.

    How It Is Done

    The health professional taking a sample of your blood will:

    • Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
    • Clean the needle site with alcohol.
    • Put the needle into the vein. More than one needle stick may be needed.
    • Attach a tube to the needle to fill it with blood.
    • Remove the band from your arm when enough blood is collected.
    • Put a gauze pad or cotton ball over the needle site as the needle is removed.
    • Put pressure on the site and then put on a bandage.

    What Is Lyme Disease How Does My Dog Get Infected

    Lyme disease is an infectious disease caused by bacteria called Borrelia. The bacteria are most commonly carried by the deer tick . Infection occurs when a dog is bitten by an infected tick. It appears that the disease is not transmitted until the tick has fed for approximately 12 hours. The tick itself becomes infected by feeding on infected mice, birds, deer, and other animals.

    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.

    The GP will ask about your symptoms and consider any rash or recent tick bites you know about.

    Lyme disease can be difficult to diagnose. It has similar symptoms to other conditions and there’s not always an obvious rash.

    2 types of blood test are available to help confirm or rule out Lyme disease. But these tests are not always accurate in the early stages of the disease.

    You may need to be retested if you still have Lyme disease symptoms after a negative result.

    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.

    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.

    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 .

    Serological Testing Of Serum For The Diagnosis Of Lyme Disease

    The most commonly used tests look for antibodies to the Borrelia species that cause Lyme disease in the UK and Europe, but they also detect infections from strains of Borrelia from the US.

    The antibody response takes several weeks to reach a detectable level, so antibody tests in the first few weeks of infection may be negative. If the first sample was taken within 4 weeks from the start of symptoms and is negative and there is a clinical suspicion of Lyme disease, then retesting in 4 to 6 weeks may be useful.

    It is very rare for patients to have negative antibody tests in longstanding infections. Borrelia antibodies persist indefinitely in some patients and this does not indicate continuing disease or a need for re-treatment.

    Serological testing for Lyme disease in the UK and much of the world follows a two-step approach using commonly available antibody screening tests as a first stage, followed by immuno-blotting of samples that give positive or indeterminate results in the screening tests.

  • Sensitive screening tests are used at the first stage of testing but have the disadvantage of occasionally detecting other diseases and producing false positive results. RIPL uses the C6 Lyme ELISA for screening

  • Samples giving positive or indeterminate preliminary screening test results are then tested in a more specific system to confirm the presence of Borrelia-specific antibodies. RIPL uses the Borrelia ViraChipĀ® IgG, IgM test for this purpose
