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.
Signs And Symptoms Of Untreated Lyme Disease
Seek medical attention if you observe any of these symptoms and have had a tick bite, live in an area known for Lyme disease, or have recently traveled to an area where Lyme disease occurs.
Untreated Lyme disease can produce a wide range of symptoms, depending on the stage of infection. These include fever, rash, facial paralysis, and arthritis.
The appearance of the erythema migrans rash can vary widely.
- Fever, chills, headache, fatigue, muscle and joint aches, and swollen lymph nodes may occur in the absence of rash
- Erythema migrans rash :
- Occurs in approximately 70 to 80 percent of infected persons
- Begins at the site of a tick bite after a delay of 3 to 30 days
- Expands gradually over several days reaching up to 12 inches or more across
- May feel warm to the touch but is rarely itchy or painful
- Sometimes clears as it enlarges, resulting in a target or bulls-eye appearance
- May appear on any area of the body
- Does not always appear as a classic erythema migrans rash
Swollen Knee
- Severe headaches and neck stiffness
- Additional EM rashes on other areas of the body
- Arthritis with severe joint pain and swelling, particularly the knees and other large joints.
- Intermittent pain in tendons, muscles, joints, and bones
- Heart palpitations or an irregular heart beat
- Episodes of dizziness or shortness of breath
- Inflammation of the brain and spinal cord

Lyme Disease Treatment Options
Early detection and treatment of Lyme are crucial. Most Lyme disease infections clear up with the help of a course of antibiotics you can take at home.
In some cases, however, people who are treated with antibiotics may continue to experience symptoms. When this happens, its called chronic Lyme disease or post-treatment Lyme disease syndrome. Doctors may treat chronic Lyme disease with a continued course of antibiotics, but the treatment often also involves managing symptoms like pain and inflammation.
If youre experiencing symptoms of Lyme disease and think you may have been bitten by a tick and were in an area where it is common, seek medical care as soon as possible. If certain symptoms and risk factors are present, doctors will typically treat for Lyme disease without waiting for a test result.

Final Lyme Disease Diagnosis
Our regular pediatrician wasnt working in the office that morning, so her colleague saw us. My son already had his shirt off when she walked into the exam room. She took one look at him and said yup. Thats lyme disease. She had another doctor give a second opinion, and my son was immediately put on antibiotics. She administered a lyme disease test just in case, but we werent taking any chances. Lyme disease treatment was started immediately.
Needless to say, we no longer go to our regular pediatrician. As the doctor, it was her job to rule out the possibility of lyme disease in my children given the fact that we live in Maryland. What the heck do I know?! I didnt get a medical degree.
My husband also had lyme disease we soon found out. Two of my men, one of whom wasnt even in New Hampshire, were obviously hit with tick bites in our Maryland neighborhood.
Management Of Individuals Without Symptoms Following A Tick Bite
Diagnostic testing is not recommended for individuals who do not develop any symptoms suggestive of Lyme disease after a tick bite.
Some commercial companies offer services to test removed ticks for the presence of the bacteria that cause Lyme disease. UKHSA does not provide such tick-testing services. The results of such tests should not be used to inform diagnosis or treatment. A positive result does not mean that the infected tick will have passed on the bacteria there are many factors that determine whether Lyme disease results from the bite of an infected tick. A negative result may not be technically valid and could give false assurance, as it does not exclude the possibility that another tick elsewhere on the body has been missed by the patient.
UKHSA runs a tick surveillance scheme and is happy to receive ticks for species identification and to monitor tick distribution.

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
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.

Lyme disease, caused by spirochetal bacteria, is found in wild animals, particularly deer and rodents. Ticks carry the disease between these animals, as well as to humans. To test for this disease, use a two-step process that consists of the ELISA test and the Western blot test. Before these tests are performed, a doctor will use your likely exposure to the disease and your presentation of symptoms to determine if they should do these tests.

Lyme Disease In Europe And Asia
Lyme disease can also occur in Europe and Asia, where Borrelia garinii and Borrelia afzelii are most commonly found.
Ticks infected with a Lyme disease bacterium can be found in woodlands across the European continent from northern Turkey to northern Sweden. However, Lyme disease is considered endemic in central Europe, where the following countries have the highest tick infection rates: Austria, Czech Republic, southern Germany,Switzerland, Slovakia, and Slovenia. In Europe, Lyme disease is primarily transmitted by the castor bean tick.
Lyme disease has been reported throughout Asia, as well, such as in Russia, Mongolia, northern China, Japan, and Koreaâ âthough infection from a Lyme disease bacterium appears to be relatively uncommon in these areas. In Asia, Lyme disease is transmitted by the taiga tick .

Its not always easy to tell if you have Lyme disease because the symptoms resemble those of many other conditions. However, this article should help you better understand the condition and how to reduce your risk of developing it.
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.

When Not To Take This Lyme Disease Test
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 its 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.
What To Do When You Get Bit By A Tick
If you get bit by a tick and you have the tick in your possession, get it tested at your local testing facility. The facility will likely test it for Borrelia burgdorferi. We also recommend you get tested as well, even if you are not experiencing symptoms or you did not get a bullseye rash. Nearly half of the people who contract Lyme disease dont even show signs of a bullseye rash.
If you think you may have Lyme disease and you have been dealing with symptoms for months or even years, you are likely disillusioned with your health journey and you need some well-deserved answers. You dont have to accept your symptoms as a life sentence as even the most complex cases can be helped.

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.
What Increases Your Risk
The main risk factor for Lyme disease is exposure to ticks that are infected with Lyme disease bacteria. In areas where Lyme disease is widespread, such as the eastern and south-central areas of Canada, southern British Columbia, and northeastern United States, several factors may increase your risk, including:
- Spending time outdoors during the warm months of the year when ticks are most active. This is usually between May and November, with peak activity in June and July.
- Having indoor/outdoor pets. They can bring infected ticks into the house. Although dogs and cats can become infected with the Lyme disease bacteria, they cannot pass the illness to humans. But the infected ticks can drop off the animal and then bite and infect a person.
- Having a stone fence or a bird feeder near your house. Stone fences often become homes for mice, and mice may feed on spilled seed from a bird feeder. Where there are mice, there are ticks.
Remove ticks right away, as soon as you notice them. Your risk for getting Lyme disease increases the longer a tick is attached to your body. Ticks generally cannot transmit Lyme disease until they are attached for at least 36 hours.

The Chance Of Getting Lyme Disease
Not all ticks in England carry the bacteria that causes Lyme disease.
But itâs 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. Theyâre 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.
