How Much Do At
Generally, at-home Lyme disease tests cost around $100, while others may cost closer to $500. The difference comes down to how many pathogens you are hoping to test for. On average, the test will look for two or three, but more expensive tests may screen for 10 to 15.
Depending on your insurance and which test you select, it may be covered. Another option is to pay for the Lyme disease test with your HSA/FSA, since some companies will accept that as a payment form.
Lyme Disease Pcr Testing
A polymerase chain reaction test, also known as a PCR test, checks blood for evidence of a pathogens DNA. In some cases, a PCR test will be performed using a sample of synovial fluid, which is found in the joints. This test has become very common in the past two years because of the COVID-19 pandemic. Millions of people have had to undergo PCR testing for coronavirus.
A Lyme disease PCR test is designed to look for the borrelia bacterias DNA to identify whether or not it has made its way into the body through a bite from an infected tick. When DNA material is found, it can be determined that a Lyme infection is present.
Image by on The PCR test looks for DNA that confirms a case of Lyme disease is present.
Early Localized Lyme Disease
Early localized Lyme disease usually presents as an acute illness characterized by:
- the presence of a single, localized skin lesion known as erythema migrans
Not all patients will present with an EM. Therefore, diagnosis should not be based solely on the presence of EM.
Most patients will present with EMs within 7 days of the initial tick bite. However, the incubation period can vary between 3 and 30 days.
The skin lesion is characteristically an annular erythematous lesion greater than 5 cm in diameter that:
- slowly increases in size
- is usually painless and non-pruritic
The lesion sometimes develops central clearing, but it can be more homogenously erythematous. In dark-skinned patients, the rash may appear more as a bruise.
Variations of an EM are highly suggestive of Lyme disease and can take the following forms:
- blue-purple hues
- a bull’s-eye appearance
A skin lesion called erythema migrans can develop into a bull’s-eye at the site of a tick bite. It is shown here on a patient’s upper arm.Footnote 1
A typical sign of early non-disseminated Lyme disease is an expanding rash called erythema migrans. This can take on the appearance of a bull’s eye.Footnote 1
Some Lyme disease skin lesions are uniformly red and do not appear with the classic ring.Footnote 1
Some patients present with a central blistering lesion, commonly mistaken as a spider bite. This is likely due to an inflammatory reaction to the pathogen induced by the tick.Footnote 1

Lyme Blood Culture: C
A United States lab called Advanced Laboratory Services had a Lyme disease blood culture that may have good predictive value in finding Lyme infection. Note: ALS no longer offers this tests. Traditionally the problem with Lyme blood culture has been finding a substance to grow the Lyme germ. ALS has perfected a method that involves three separate steps. In the first step the blood is incubated on a special modified BSK medium. Then after 2 weeks it is transfered to a medium that has a protein matrix. As a third step a PCR techinique is use to determine if the growth on the medium is really borrelia. PCR is a techinique that finds the dna of an infection, in this case borrelia.
There is one study of this technique performed by Eva Sapi PhD and her research group. Of note the research was supported by ALS and Dr. Sapi is a member of the Research Division at ALS. This means there is an inherent bias built into the results of the research to find a positive result supporting the effectiveness of the test.
The test included 72 people who were known to have Lyme based on the very strict standards of the CDC and IDSA. There were also 50 people put in a control group who did not have Lyme. The study results found 94% sensitivity and 100% specificity.
In fact in my limited use of this test I found it missed many that I diagnosed with Lyme disease based on other tests and clinical grounds.
How Do Patients Test Negative For Lyme Disease In Ireland But Test Positive For Lyme Disease In Another Country
Laboratories in Ireland generally follow the laboratory testing recommendations of the US Centres for Disease Control and Prevention , the Infectious Disease Society of America , the European Federation of Neurological Societies and the British Infection Association .
The antibody tests used in Ireland are made by commercial companies and meet strict quality criteria. Irish laboratories have their own quality assurance methods to make sure the tests are working correctly as well as being accredited by the Irish National Accreditation Body to perform the test correctly.
Testing which is performed abroad may be performed in laboratories which have not met National or International Accreditation . In some cases they may use tests which are made in the laboratory rather than purchased from commercial companies. These tests may not have the same or consistent levels of quality as commercial tests which must meet specific European criteria called CE marking. These tests may be more likely to give a false positive result for those reasons.
Some laboratories abroad do not use antibody tests like the EIA and western blot and instead will use other types of tests. For example, testing for levels of a specific white blood cell or lymphocyte transformation tests . These types of tests are not currently recommended by international groups such as the CDC, IDSA or BIA for a number of reasons:

What Is The Treatment For Lyme Disease
Lyme disease can be treated and cured in all the stages. 14 to 21 days course of oral antibiotics are commonly used to treat the disease in its early stages. The medications used are doxycycline , and cefuroxime and amoxicillin
The later stage of Lyme disease that involves the central nervous system is treated with intravenous antibiotics for a course of 14 to 28 days. Sometimes, these intravenous antibiotics can cause various side effects that include a lower white blood cell count, diarrhea, colonization, or other infection.
Some people might experience symptoms such as joint pain and muscle weakness even after the treatment. This condition is known as post-Lyme disease syndrome and the cause of this syndrome is not known to date. In this case, treating with antibiotics is also ineffective.

How To Test For Lyme Disease
Wondering how to get tested for Lyme disease? The Centers for Disease Control and Prevention suggests a two-step testing process to check for a Lyme disease infection, both of which involve antibody testing , typically done on the same blood sample.
If the first step in the process returns a negative test result, then the second step is not necessary. However, if the first step yields a positive result, the second test is recommended as confirmation of a Lyme disease diagnosis. The Everlywell Lyme Disease Test follows this recommended protocol from the CDC, so it includes the two-step testing process.
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.

What Health Professionals Need To Know About Lyme Disease
Lyme disease is a serious illness caused by the bacterium Borrelia burgdorferi. The bacterium is a spirochete transmitted by certain species of Ixodes ticks. It is spread through the bite of infected blacklegged ticks and western blacklegged ticks.
Health professionals are encouraged to further their knowledge of Lyme disease in Canada. This includes the ability to:
- understand and identify the signs and symptoms
- prescribe appropriate treatment for patients diagnosed with the disease
- report human cases through appropriate channels
Symptoms sometimes appear in overlapping stages, as:
- early localized Lyme disease
- early disseminated Lyme disease
- late disseminated Lyme disease
It is important to note that some people with Lyme disease may have no or minimal symptoms. Others may suffer more severe symptoms.
Some people may not develop symptoms until weeks after the initial bite, as described in the early localized disease stage below. In this case, they may not remember the tick bite or associate the illness with the bite. Because the blacklegged tick is so small and usually painless, some people may not even know they were bitten by a tick.
Health professionals should be knowledgeable about the clinical manifestations and epidemiological risk factors of Lyme disease. Consider Lyme disease as part of your differential diagnosis in a patient who presents with compatible symptoms and signs.
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.

Question 5 How Do The Sttt And Mttt Detection Methodologies Compare
The MTTT appears to provide similar or improved sensitivity and specificity compared to the STTT. In a 356-sample retrospective study of a heterogenous cohort, specimens from healthy and disease control subjects and patients characterized as having stage I , stage II , or stage III Lyme disease were tested with both the STTT and MTTT approach.4 The results are summarized in Table 1. The MTTT methodology showed improved sensitivity relative to STTT for Lyme stages I and II, with statistically comparable sensitivity for stage III Lyme disease specificity did not differ significantly between the 2 methods.4
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. PHE 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.
PHE runs a tick surveillance scheme and is happy to receive ticks for species identification and to monitor tick distribution.
What Is Lyme Disease
Lyme disease is an illness caused by infection with a bacteria that is spread through the bite of certain kinds of ticks. Symptoms can affect the skin where the bite occurred or elsewhere on the skin and may progress to affect other parts of the body. A family of bacteria, known as Borrelia, causes Lyme disease.
Newer Immunoblot Using Synthetic Proteins From Igenex: Grade A
In an immunoblot using synthetic proteins grown in bacteria through recombinant dna, only the protein regions specific for Lyme on protein 31, 41, and 93 are grown. This decreases the chances of a false positive testing which I outlined above in the western blot section. In this method, like the western blot above, attention is still paid to certain Lyme specific proteins.
IGenex goes one step further in its new Lyme Immunoblot test and uses 8 different strains of Lyme proteins. These include: B. burgdorferi B31, B. burgdorferi 297, B. californiensis, B. mayonii, B. spielmanii, B. afzelii, B. garinii and B. valaisiana.
Using internal validation standards, an IGM Immunoblot is positive if there are antibodies attached to 2 of the following four proteins: 23, 31, 39, and 41. The IGG Immunoblot is positive if there are antibodies attached to 2 of the following 6 proteins: 23, 31, 34, 39, and 41.
Based on internal validation studies, IGenex reports the tests has a sensitivity of 90.9% and a specificity of 98%. This means this is by far the best test at finding Lyme with a very limited chance of false positives.
Grade: A-. The only reason I do not give this test an A grade is that it still misses 9% of Lyme. This can occur for a variety of reasons including immune suppression making it difficult to make antibodies or due to Lyme hiding where the immune system cannot see the germ.

What Happens If You Go Untreated For Lyme Disease
If you happen to test positive for Lyme disease but go untreated, then your symptoms may increase significantly. You may develop early-onset arthritis, facial palsy, and inflammation of the brain stem and spine. Those symptoms can affect how your brain works and your ability to function cognitively.
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
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
- 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.

Question 10 What Other Infections Can A Tick Transmit To Humans Besides Lyme Disease
I scapularis ticks can also carry other human pathogens that have a high degree of symptom overlap, including Borrelia miyamotoi, Anaplasma phagocytophilum, Ehrlichia chaffeensis, and Babesia microti.2,10-12 Several studies on co-infected ticks indicate as many as 20% of Ixodid ticks can be coinfected with B burgdorferi and one or more of these other tick-borne human pathogens.10-12
Molecular tests can be useful to detect these organisms in early/acute stages of infection, when genetic material from the pathogen can be detected but antibodies remain below the limit of detection of serologic assays.2,10-12 Quest offers molecular and/or serological tests for B burgdorferi, B miyamotoi, A phagocytophilum, E chaffeensis, and B microti, individually and in 2 panels .
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.
