Blood Tests For Lyme Disease

How Will Pregnancy Affect Treatment For Lyme Disease

Lyme Disease Serologic Testing

Early treatment of Lyme disease during pregnancy is important. Thats because if Lyme disease is 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.

Cdc Supports The Development Of New Tests

New tests may be developed as alternatives to one or both steps of the two-step process. Before CDC will recommend new tests, they must be cleared by the Food and Drug Administration . For more details, see: Recommendations for Test Performance and Interpretation from the Second National Conference on Serologic Diagnosis of Lyme Disease.

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 UK Health Security Agency Porton where ISO15189 accredited confirmatory testing is also provided. RIPL also provides 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.

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

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.

These tests may come in handy if youre an avid outdoors person who lives in geographical areas where ticks are present.

When choosing at-home Lyme disease tests to feature, we looked at affordability, accuracy, ease in reading directions, and what made the specific tests stand out from the crowd.

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

What Do The Test Results Mean

Lyme Disease Borrelia IgM Antibodies Blood Test

Because there are three tests that are typically conducted for the Lyme disease blood test, then results can vary based on the combination of test results received. When all three tests are positive, then Lyme disease is likely. These other result combinations are usually interpreted in the following ways.

Positive IgM, Negative IgG, Negative Western Blot.This usually indicates that the Lyme disease infection is in its early stages or that the blood test has produced a false positive result.

Negative IgM, Positive IgG, Positive Western Blot.This is usually interpreted as having a late-stage Lyme disease infection. It may also be an indication that someone had a previous infection that has been removed from the body.

All results negative.This is usually interpreted as there not being any infection present and that the symptoms are being caused by another issue. In some specific instances, however, it can also be seen as the antibody levels being too low to detect.

Once Lyme disease is confirmed, there will almost always be detectable levels of the bacteria which causes the disease in the IgG antibodies in their blood. This will mean that their IgG blood test results will have a standard deviation in what is considered as normal because of the presence of the disease, even if it has been effectively cured.

The Importance Of Diagnostic Tests For Borrelia

Called the great imitator,Lyme disease can present a variety of symptoms that mimic a wide range of illnesses, including chronic fatigue syndrome, fibromyalgia, ALS, Alzheimers disease, depression, insomnia, and autoimmune disorders such as RA and Multiple Sclerosis . In addition, many tick-borne infections go misdiagnosed for months because these nonspecific symptoms mirror other illnesses. Thus, laboratory testing is frequently required to confirm a diagnosis.

Lyme Disease Antibody Test Procedure

The Lyme disease antibody test requires no advance preparation. A lab technician will swab the inside of your elbow with an antiseptic before drawing your blood. Your blood will be drawn from a vein in your arm using a small needle.

The blood draw should not be painful, though you might feel a slight prick when the needle is inserted into your vein.

The blood sample will be collected in a vial. The puncture site will be bandaged, if needed, after the needle is removed. After the blood draw, you are free to go home.

There are very few risks associated with the Lyme disease antibody test. Excessive bleeding is possible, but there may be an increased risk if you take blood thinning medications or certain anti-inflammatory drugs like:

Investigation Of Suspected Neurological Lyme Disease

The diagnosis of neurological Lyme disease can only be confirmed by examination of the CSF and a paired serum sample. A definite diagnosis is based on the presence of a pleocytosis in the CSF, demonstration of intrathecal synthesis of specific antibodies to Borrelia species in CSF by comparison to serum and the presence of neurological symptoms. It is not possible to confirm intrathecal synthesis and hence definite neurological Lyme disease without a paired serum .

In 2018 RIPL introduced a service for the detection of intrathecal synthesis of Borrelia-specific antibodies which is summarised in this flow diagram. An accessible text version of this flowchart is available below.

Clinicians may ask for guidance on laboratory testing of CSF from RIPL if required.

Lyme disease is being increasingly recognised as causing illness and hardship, if the diagnosis is missed. Over the last number of years, there has been a marked increase in awareness of the condition among GPs and hospital doctors in Ireland. Each of the HSEs Hospital Groups have a number of Infectious Disease Consultants who are expert in the diagnosis and management of Lyme disease. If you have been bitten by a tick or have other reasons to strongly suspect you may have Lyme disease, you should visit your GP for advice.

What Is On The Horizon For Lyme Testing

Because Lyme bacteria are not usually present in high enough numbers to be detectable, blood tests to look for Borrelia are not helpful.

Better diagnostic tests are needed that are direct and can detect infection at all stages of Lyme disease. Researchers are studying new diagnostic methods using better antibody tests, direct detection methods, and different ways to measure immune response to Lyme disease.

Notice To Readersrecommendations For Test Performance And Interpretation From Thesecond National Conference On Serologic Diagnosis Of Lyme Disease

The Association of State and Territorial Public HealthLaboratory Directors, CDC, the Food and Drug Administration, theNational Institutes of Health, the Council of State and TerritorialEpidemiologists, and the National Committee for Clinical LaboratoryStandards cosponsored the Second National Conference on SerologicDiagnosis of Lyme Disease held October 27-29, 1994. Conferencerecommendations were grouped into four categories: 1) serologictest performance and interpretation, 2) quality-assurancepractices, 3) new test evaluation and clearance, and 4)communication of developments in Lyme disease testing. Thisreport presents recommendations for serologic test performance andinterpretation, which included substantial changes in therecommended tests and their interpretation for the serodiagnosis ofLD.

It was recommended that an IgM immunoblot be consideredpositive if two of the following three bands are present: 24 kDa * , 39 kDa , and 41 kDa . It was furtherrecommended that an that IgG immunoblot be considered positive iffive of the following 10 bands are present: 18 kDa, 21 kDa *,28 kDa, 30 kDa, 39 kDa , 41 kDa , 45 kDa, 58 kDa , 66 kDa, and 93 kDa .

Laboratory Tests That Are Not Recommended

Some laboratories offer Lyme disease testing using assays whose accuracy and clinical usefulness have not been adequately established. Examples of unvalidated tests include:

  • Capture assays for antigens in urine
  • Culture, immunofluorescence staining, or cell sorting of cell wall-deficient or cystic forms of B. burgdorferi
  • Lymphocyte transformation tests
  • In-house criteria for interpretation of immunoblots
  • Measurements of antibodies in joint fluid
  • IgM or IgG tests without a previous ELISA/EIA/IFA

How to Prepare for the Test

You do not need special steps to prepare for this test.

How the Test will Feel

When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away.

Why the Test is Performed

The test is done to help confirm the diagnosis of Lyme disease.

Normal Results

A negative test result is normal. This means none or few to Lyme disease were seen in your blood sample. If the ELISA test is negative, usually no other testing is needed.

Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your health care provider about the meaning of your specific test results.

Can Ticks On Cats Transfer To Humans

Ticks are unpleasant parasites that may affect your cat and if your cat is bitten, the tick may even pose a risk to people in your household. Ticks can also carry diseases. The bacterial infections including Lyme disease can be carried by ticks and passed to cats and even people, if they get a chance to bite.

What Are Alternative Diagnostic Testing Approaches

Patients with EM who live in or have traveled to areas endemic for Lyme disease can be diagnosed clinically without testing. For all other patientsthose with atypical early disease or signs of disseminated infectionlaboratory testing is necessary. Testing patients with low epidemiologic risk is generally not useful, but if pursued, clinicians must recognize the high likelihood of false positives.

Using EIA or immunoblot alone is insufficient for diagnosing Lyme disease because of reduced specificity and potential for false positives.3

Polymerase chain reaction assay of blood has low sensitivity because of the short duration of spirochetemia. PCR of synovial fluid or skin biopsy samples may be useful in certain clinical situations if specimens are available.3

Laboratory-developed tests for Lyme disease are offered by some commercial laboratories claiming to specialize in Lyme disease testing. These nonstandardized tests lack adequate clinical validation and FDA clearance and are not recommended.10

Molecular Testing For Detection Of Borrelia Species Bacterial Dna

Rapid test for Lyme disease

PCR is available for Borrelia species DNA detection but is of limited value in routine testing for Lyme disease because the organism is only present in blood during the early stages of the disease and is predominantly restricted to the affected tissues.

Diagnostic molecular testing for Borrelia species DNA is available on request for relevant specimen types. Please call RIPL to discuss individual cases.

How Much Does A Lyme Disease Test Cost

The cost of a Lyme disease test depends on what type of test is performed an ELISA test or a combination of ELISA and western blot tests.

Averagely, the cost for an ELISA test for Lyme disease is in the vicinity of $120 or more. If you include a confirmation western blot test, it can attract an additional $130 or more. More details on pricing can be referenced on our website.

Although an ELISA test might come back negative, it is best to combine it with a western blot test because not everyone shows the rash or bulls eye symptoms of Lyme disease.

After a successful diagnosis and treatment, it is equally important to do a follow-up test for Lyme disease years later to be sure that any similar flu-like symptoms are something else and not the same disease reoccurring.

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.

Can Lyme Disease Be Detected By A Blood Test

In a word: yes!

A blood test does not only detect Lyme disease it is the most accurate and preferred test for diagnosing the disease. If a patient with Lyme disease shows signs that the central nervous system has been affected by the disease, western blot testing on the cerebrospinal fluid can be performed. If ordering from Walk-In Lab, a doctors note is not needed. Just pick your Lyme disease test and place your order online.

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 doctor 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.

What Bands Are Positive For Lyme

Some Lyme specialists and scientists believe that there are five very specific bands on the Western blot test that are highly indicative of Lyme disease: band numbers 23, 31, 34, 39 and 93. If any of these bands are positive and the patient is experiencing symptoms of Lyme disease, they may feel treatment is warranted.

Is There A Lyme Disease Test Kit

Blood collection kits are available for at-home Lyme disease testing. Lyme disease test kits can cost as less as $20 and as much as $100 or more. Using a Lyme disease test kit is as simple as pricking your finger and smearing or collecting the blood onto the kit for testing.

However, testing for Lyme disease in a more controlled environment such as a lab or clinic is preferable as qualified healthcare professionals are likely to perform a more reliable test.
