Should You Get A Test For Lyme Disease

Testing for Lyme DiseaseWhat You Need to Know

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.

To Halt The Spread Of Lyme Nantucket Residents Consider Genetically Engineered Mice

Her ordeal is a common one every year, some 300,000 people in the United States are diagnosed with Lyme disease, according to the Centers for Disease Control and Prevention, and that number is on the rise. Some people wait months or years to get a correct Lyme diagnosis. And their cases highlight a problem: Tests for Lyme in the first month of infection are frequently wrong. When diagnosed and treated early the infection is a simple one to get rid of, but left untreated it can cause a myriad of lingering symptoms, from severe arthritis to short-term memory problems.

Now, a number of research groups are working to improve Lyme tests to catch infections in the early stages. One avenue being studied by the CDC aims to create a Lyme signature of small molecules in the blood an approach that, in early testing, catches a dramatically higher share of early infections.

What Causes Lyme Disease

Lyme disease is caused by bacteria that is spread to humans by tick bites. The ticks that carry the spirochete are:

  • Black-legged deer tick

  • Western black-legged tick

Ticks prefer to live in wooded areas, low-growing grasslands, and yards. Not all ticks carry the Lyme disease bacteria. Depending on the location, anywhere from less than 1% to more than 50% of the ticks are infected with it.

While most tick bites are harmless, several species can cause life-threatening diseases. Tick-borne diseases include:

  • Rocky Mountain spotted fever

What Is The Most Accurate Test For Lyme Disease

Lyme disease is more common than many people think. Figures from the Center for Disease Control suggest that roughly 300,000 Lyme disease cases occur every year in the US.

The numbers are alarming, but it gets worse as finding accurate diagnostic tests can be challenging. Although the disease is treatable, it is nearly impossible to tackle it effectively if it is not diagnosed accurately and early enough.

Late detection can lead to severe health problems such as arthritis, heart blockage, and inability to concentrate, among other problems.

Given the prevalence and seeming elusiveness of the disease, some of the logical questions concerned persons would ask are: what is the most accurate test for Lyme disease? And when should I get checked for Lyme disease? This article will proffer answers to these and many other related questions. But first, a little background would be in order.

When Should I Get Checked For Lyme Disease

What Is The Most Accurate Test 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
  • Fatigue
  • Headaches
  • Fever

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
  • Dizziness
  • 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.

What Happens During Lyme Disease Testing

Lyme disease testing is usually done with your blood or cerebrospinal fluid.

For a Lyme disease blood test:

  • A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

If you have symptoms of Lyme disease affecting your nervous system, such as neck stiffness and numbness in hands or feet, you may need a test of cerebrospinal fluid . CSF is a clear liquid found in your brain and spinal cord. During this test, your CSF will be collected through a procedure called a lumbar puncture, also known as a spinal tap. During the procedure:

Can Lyme Disease Be Detected By A Blood Test

What’s the Best Test for Lyme Disease?

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.

The Blood Tests Can Have False Positives

The blood tests can trigger false positives, suggesting that you have the disease when you really dont. This can happen in up to one out of four tests.

This can lead to unnecessary treatment with antibiotics. These drugs are usually safe, but they sometimes cause side effects, such as nausea, vomiting, diarrhea, and increased sensitivity of the skin to sunlight. In rare cases, they can even cause dangerous allergic reactions.

Using too many antibiotics can also lead to the growth of drug-resistant bacteria. This means that bacteria in your body may get stronger and more difficult to treat with antibiotics in the future.

A false positive can also lead to more unneeded blood tests, urine tests, X-rays, and doctor visits.

If you have a false positive, you may not get treated for the real cause of your pain. For example, rheumatoid arthritis is a disease that causes joint pain. It can lead to permanent and severe joint damage if you do not start taking the right medicines as early as possible.

Lyme Disease Test Western Blot

Labs performing a Western blot use electricity to separate proteins called antigens into bands. The read-out from the Western blot looks like a bar code. The lab compares the pattern produced by running the test with your blood to a template pattern representing known cases of Lyme disease. If your blot has bands in the right places, and the right number of bands, it is positive.

The CDC requires 5 out of 10 bands for a positive test result. However, because some bands on the Western blot are more significant than others your doctor may decide you have Lyme disease even if your Western blot does not have the number of bands or specific bands recommended by the CDC. Different laboratories use different methods and criteria for interpreting the test, so you can have a positive test result from one lab and a negative test result from another.

The chart below will help you understand how to interpret the western blot test.

Sample Types For Lyme Disease Testing

For routine Lyme disease serological testing, you must send a serum sample .

For testing for neurological Lyme disease, you must send paired CSF and serum samples taken on the same day. If possible, please provide CSF cell count and total albumin, IgG and IgM values. If albumin, IgG and IgM measurements are not available, RIPL will make arrangements for these measurements at additional cost.

PCR testing is available. We recommend that specialists call RIPL to discuss appropriate sample types for PCR. These may include joint fluid, biopsy tissue, CSF and EDTA plasma. Please submit biopsies as fresh tissue in a sterile container, ideally with a drop of sterile saline to prevent the tissue drying out.

How Do You Diagnose The Later Stages Of Lyme Disease

The Right Lyme Disease Test

Disseminated Lyme disease, due to unsuccessful or delayed treatment, can become disabling. The bacteria can leave the skin where it was initially inoculated by the tick and travel through the bloodstream to numerous systems of the body, primarily joints, heart, brain, muscles and the nervous system.

Late disseminated Lyme disease has a wide range of presentations including joint pain, extreme fatigue, neuromuscular pain, cardiac problems, headaches, and other central nervous system dysfunction. There are some distinguishable signs of later stage Lyme disease including facial palsy in the second stage, and swollen knees in the third stage that are somewhat specific for Lyme disease, but not absolutely, because there are other causes of Bells Palsy and swollen knees.

Diagnosis can be confirmed by serology blood tests which measure the antibodies that are formed by the immune system in response to the Lyme disease bacterial infection. Collection of cerebrospinal fluid by lumbar puncture may be indicated in neurologic cases that may involve the central nervous system.

The Best Test For Lyme Disease

Lyme disease is a tick-borne illness spread by Lyme borreliaebacteria which includes, but is not limited to, Borrelia burgdorferi sensu stricto. The Centers for Disease Control and Prevention estimate that there are 400,000 cases of Lyme disease annually, making Lyme a serious public health concern that only stands to grow as the spread of ticks affects disease endemicity and seasonality.

One of the biggest challenges of fighting Lyme disease is providing patients with accurate diagnostic tests. Without access to the best tests for Lyme disease, its impossible to diagnose this treatable disease in a timely manner. When the disease isnt caught in time, it can spread throughout the body and cause chronic health problems that could otherwise be avoided with earlier detection and treatment.

What If Lyme Disease Goes Untreated

If Lyme disease goes untreated, it can affect other systems in the body. According to the , common symptoms of later stage Lyme disease include:

  • severe headaches and neck stiffness
  • additional erythema migrans rashes on other areas of the body
  • facial palsy, which is a loss of muscle tone or droop on one or both sides of the face
  • arthritis with severe joint pain and swelling, particularly in the knees and other large joints
  • intermittent pain in tendons, muscles, joints, and bones
  • heart palpitations or an irregular heartbeat
  • episodes of dizziness or shortness of breath
  • inflammation of the brain and spinal cord
  • nerve pain
  • shooting pains, numbness, or tingling in the hands or feet

So When Do You Need Blood Tests For Lyme Disease

In some cases, you can have Lyme disease without the rash. Or you may not see the rash before it goes away on its own.

In these cases, your doctor should ask you about your medical history and do a thorough physical exam. Your doctor should look for these signs that you might have Lyme disease:

  • You were in an area with ticks and Lyme disease.
  • You also have fever or redness, warmth, and swelling in one or a few joints at a time usually the knees, shoulders, or wrists.

Other symptoms can occur later on. Talk to your doctor about testing and treatment choices.

Negative C6 Elisa On Serum

Do you know the signs of Lyme disease?

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.

Persistent Lyme Disease Symptoms Arent Helped By Long

Microbiologist Elli Theel, who directs the Infectious Diseases Serology Laboratory at Mayo Clinic, calls the 2015 study incredibly promising. The sensitivity they showed just in early Lyme disease patients was very high, the highest Ive actually seen, she said.

In an upcoming publication, the researchers also showed that metabolomics can differentiate Lyme from a similar tick-borne disease called southern tick-associated rash illness . The disease causes similar symptoms as Lyme, including a bullseye rash, and occurs in overlapping geographic regions. Currently there is no laboratory test to diagnose STARI, and little is known about how the disease progresses and how to treat it, something Molins hopes will change with better testing.

Tbrf Can Cause A Negative Result

The disease Tick-Borne Relapsing Fever is caused by a similar but totally separate species of Borrelia to the bacterium that causes Lyme disease and also causes Lyme-like symptoms. However, if a patient with TBRF takes a Lyme disease test, the TBRF will not show up, causing the Lyme test to be negative even though the patient is still sick with an infection.

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.

How Is It Diagnosed

If youâve been outside in an area where ticks are known to live, you should tell your doctor. Theyâll also want to know about the symptoms youâre having. These details are crucial to making a diagnosis of Lyme disease.

Early symptoms that usually occur within the first month after a tick bite can include:

  • Rash at the site of the tick bite that may look like a âbullâs-eyeâ
  • Racing heart
  • Problems with your short-term memory

Symptoms that come and go are common with Lyme disease. They will also depend on the stage of the disease.

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. 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 is introducing a service for the detection of intrathecal synthesis of Borrelia-specific antibodies which is summarised in this flow diagram.

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