What Is An At
An at-home Lyme disease test will typically be a blood finger prick test.
If you have been exposed to the bacteria Borrelia that leads to the infection of Lyme disease, your body will have created two antibodies to fight it off. The test will look for the presence of both types of antibodies, known as immunoglobulin M and immunoglobulin G .
You will receive your test kit along with account information so that you can get your test results as soon as theyre ready. Follow the manufacturers instructions exactly as they are described.
Each test has different instructions, so its important to read the kits detailed information before getting started.
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. The 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

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.
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.
Have You Been Bitten By A Partially Fed Tick
Investigators suggest that transmission time may be shorter if a tick has already fed on a host. A study by Shih and colleagues, found that, Partially fed nymphal ticks transmit spirochetal infection more rapidly than do ticks that have never been attached to a host.¹
So, how quickly a tick can transmit Lyme disease may depend on whether the tick had been partly fed BEFORE it attached to its second host.
Shih et al. demonstrated that partially fed nymphal ticks were capable of transmitting spirochetes to a non-infected mouse within 24 hours. The authors discovered it took less time for an infected nymphal deer tick to transmit Lyme spirochetes to a mouse if the tick was partially fed.

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.

How Can Lyme Disease Be Prevented
Tick control and prevention methods significantly reduce the likelihood of infection. Maintaining antibodies against B. burgdorferi through vaccination can further protect your animal. Antibody amounts and duration of vaccine antibodies can vary in individuals. Verifying your animals antibody response to vaccination helps to assure durable protection.
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.

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.

How Do You Know If You Have Lyme Disease
The answer to the question Can I testmyself for Lyme disease? must be answered in two distinct parts. Diagnosticmethods for both acute and chronic Lyme disease are very different, with thelatter being a lot more problematic than the former. First, the good news:acute Lyme disease is relatively easy to self-diagnose in most cases, at leastin theory. Lyme is spread through the saliva of ticks, which transfer the Borrelia burgdorferi bacteria to thebloodstreams of their human hosts. The acute stage of the disease begins soonafter a bite symptoms similar to the flu appear, although they are not alwayssevere. But the critical symptom for patients is the distinctive bullseye rashthat appears at the site of the bite. This takes the form of a circle inside alarger circle, and is one of the prime signs of Lyme disease. If you find this,you can almost assuredly self-diagnose Lyme, although of course you should alsosee a doctor right away with your concerns.

Are There Any Risks To Lyme Disease Tests
There is very little risk to having a blood test or a lumbar puncture.
With 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.
With a CSF test, you may feel a little pinch or pressure when the needle is inserted. After the test, you may feel some pain or tenderness in your back where the needle was inserted.
You may also have some bleeding at the site or get a headache. The headache may last for several hours or up to a week or more, but your provider may suggest treatment to help relieve the pain.

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.
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.

You Do Not Usually Need Tests To Show That You Have Lyme Disease
In most cases, theres a clear sign of Lyme diseasea painless, spreading rash that often grows to look like a bulls eye. If you have this rash, and you recently had a tick bite or were in an area known for Lyme disease, you dont need a test. Instead, your doctor can just start treating you with antibiotics, as appropriate.

How Is Lyme Disease Diagnosed
Though several types of tests do exist for the diagnosis of Lyme disease, the best tests for a Lyme disease diagnosis are blood tests, also known as serological tests. These tests are indirect, meaning they dont detect the infecting bacteria or its antigens but rather the antibodies an infected persons body produces in response to these antigens.

Where Do Ticks Typically Live
Ticks are typically found on the underside of low lying shrubs and brush, in areas between forests and open grass and especially in areas where there are deer. They tend to also be in higher numbers in old stone walls where mice nest. Ticks in their immature or nymphal form are carried by mice, and by deer as adults. When a human or animal goes past them, ticks latch on to the passerby and search for an area to attach and start feeding.
What Do The Results Mean
Lyme disease is difficult to diagnose. The symptoms are common to many conditions, and test results alone can’t diagnose the disease. To make a diagnosis, your provider will consider your test results along with your medical history, exposure, and symptoms. You may also need other tests.
A negative blood test result means that antibodies to fight the Lyme disease bacteria were not found in your blood. If you had symptoms for longer than 30 days before your test, you probably don’t have Lyme disease.
But if you had symptoms for less than 30 days before you gave your blood sample, you may need to have another Lyme disease test. That’s because it may take a few weeks for your body to make enough antibodies to show up on a test. If your test was done too soon, you could be infected even though your test was negative. This is called a “false negative.”
A positive blood test result means that antibodies to fight the Lyme disease bacteria were found in your blood. In this case, the Centers for Disease Control and Prevention recommends a second blood test on the same blood sample. If the second test is positive and you have symptoms of infection, you probably have Lyme disease.
But positive test results don’t always mean that Lyme disease is causing your symptoms. You could have antibodies from a past case of Lyme disease that your body successfully fought off months or even years ago.

What Can I Expect Long Term If My Child Has Lyme Disease
If Lyme disease is caught and treated early, most children will make a full recovery. Some children with Lyme disease go on to experience whats called a post-infectious syndrome with symptoms that may include feeling fatigue, joint aches and pains, headaches, difficulty sleeping, and problems concentrating. Since the infection itself is gone by this time, doctors generally dont prescribe antibiotics. Each child is different, but its not uncommon for symptoms of post-infectious syndrome to linger for months, or even years, and they can be made worse by stress or other illness. But most children do make a full recovery.
Blacklegged, or deer, ticks are very small, so it helps to know what to look for when doing a tick check. Adults are about the size of sesame seeds and in the nymph or larva stage, they can be as tiny as a poppy seeds.
Tick Identification & Testing
Tick identification and testing: Bring the tick to the San Mateo County Public Health Laboratory , located at 225 West 37th Avenue , San Mateo. To contact the laboratory, please call 573-2500. There is a $25 processing fee.
Tick identification only: San Mateo County Mosquito & Vector Control District , located at 1351 Rollins Rd, Burlingame also performs tick identification but does not perform testing related to bites. To contact SMCMCD, call 344-8592. There is no fee for tick identification. Please contact the Public Health Lab for all tick testing requests.
When dropping off a tick specimen, please provide us with contact information, location of tick bite, and duration of tick contact. Your tick must first be identified to determine if it is the Western Black-legged Tick, the species that transmits Lyme Disease. If so, the next step will be to test for the presence of Borrelia burgdorferi, the micro-organism that causes Lyme Disease, in the ticks stomach. The tick must be intact in order for this test to be performed.

Which Ticks Should I Worry About
Nymphal ticks cause most cases of Lyme disease. Because nymphs are as small as poppy seeds and their bite is painless, people often dont realize they have been bitten. Adult ticks can also infect humans, but are easier to spot and remove.
Not all ticks are infected. Because tick studies have only been done in a relatively few places, in most of the US, tick infection rates are unknown. Even in places where ticks generally do not carry Lyme, there may be hotspots of infection depending on local conditions. The tick infection rate may also change from year to year, even in one location.

How To Improve Heart Health
Anytime you have something irregular with the heart, you should have someone check it out, advises Dr. Rawls. The threshold for being evaluated for heart symptoms should be pretty low. In other words, if your heart feels off youre experiencing chest pain, shortness of breath, an irregular heartbeat, or something else get to a doctor as soon as possible.
While testing can help pinpoint whats going on, it may not always be spot on the first time youre evaluated, and you might need to be persistent in pursuing a diagnosis. From one patient to another, Stewart says, When it comes to something serious like your heart, dont stop searching for answers. Trust your instincts, and dont ignore it.
Once you know what youre dealing with, you and your doctor can establish a plan of care, which may include antibiotics, particularly in the acute stages of Lyme disease. Other drug therapies include beta blockers and antiarrhythmic drugs, which might be necessary to stabilize your heart rate and prevent abnormal rhythms. However, those drugs can come with a long list of side effects, and the length of time you could be required to take them will differ from physician to physician and the severity of your illness.
