Persistent Symptoms Following Treatment
In most cases, timely treatment according to the appropriate regimen described in the chart above is effective. However, some Lyme disease patients have persistent symptoms following treatment. Research continues into the causes and methods of treatment.
There is no definitive evidence that persistent symptoms represent ongoing infection. Post-infectious inflammation due to damage from the infectious process may respond to anti-inflammatory drugs.
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.
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 .

The Western Blot Has Its Own Issues
The WB looks for the presence of an immune response to Bb proteins, focusing on two types of antibodies: immunoglobulin M and immunoglobulin G .
When a person comes in contact with an infectious agent, the body makes IgM antibodies as its first line of defense. In general, it takes two to four weeks to be at a consistently detectable level, with production peaking at around four weeks and becoming undetectable after six months.
Persistent ongoing detectable IgM levels beyond the one-month period are subject to controversy in their meaning. Some scientists consider these false positives, while others view them as evidence of persistent infection and associated with chronic illness.
The second antibody produced in the body is IgG. It develops over four to eight weeks after exposure to Bb, peaks at approximately six weeks and is gone in less than one year.
IgG antibodies are produced to target specific threats like viruses, bacteria and other potentially harmful microorganisms, and forms the basis of long-term protection against microorganisms.
If The C6 Test Is Positive What Is The Next Step
A positive C6 test means antibodies to C6 were found. The next step is to do a QC6 test, which determines if the levels of antibody are high enough to justify treatment. If the value of the QC6 is higher than 30 IU/mL and signs of illness are present, then antibiotic treatment should be considered. If the QC6 is less than 30 IU/mL and there are no signs of illness, then treatment may not be necessary.
In addition to doing the QC6 test, your veterinarian may want to take samples of blood and urine to assess kidney function and to look for protein in the urine. A positive test for protein in the urine could signal serious underlying kidney disease.

What Do Testing Kits Typically Include
Depending on the method of collection, testing kits may include:
- a device to collect the blood, urine, or saliva sample
- a container to ship the sample back to the lab
- a shipping label
Some kits come with a bandage, wipes, and a biohazard bag. Kits may contain extras such as Styrofoam holders, labels, or tubes with varying solutions inside.
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.

Question 6 Can Serologic Testing Detect Lyme Disease Immediately After Infection
No, not immediately. Lyme disease develops in stages: the early stage, which is divided into early localized infection, early disseminated, and then a late disseminated infection.1 Spirochetemia occurs early, with widespread dissemination through tissue and body fluids. However, antibodies usually take at least 2 weeks to develop, so patients may be seronegative within 2 weeks of a suspected tick bite.1-3 The sensitivity of serologic testing increases markedly with the progression of B burgdorferi infection from early to late Lyme disease.
Identification of Borrelia species DNA in the blood by polymerase chain reaction may be useful in the first two weeks of infection.1
Lyme Suppresses The Immune System
The problems with this type of testing are many. One major difficulty in using the ELISA and WB is that the bacterial organism responsible for Lyme disease, Bb, is in itself immunosuppressive.
So how could a test that depends upon the persons immune response be much good if we know the organism suppresses the immune system? In other words, if what you are measuring can be affected by the cause of the illness itself , then depending on this test to make the LD diagnosis is questionable.
This major flaw in the recommended testing diminishes the value of the test. Unfortunately, relying on a test that is so subject to error is the weak foundation that has provided support for much of LD research. This testing is additionally problematic in many ways.

What You Should Know About Lyme Disease
If the symptoms of Lyme disease persist and there is no known cause for them, then consulting with a Lyme literate doctor may provide treatment progress. Many health insurance plans will not cover these consultations or tests, however, so proceed with caution.
For those who are treated with antibiotics, a condition called PTLD occurs that mimics the symptoms of the disease for up to 6 months.
In regions where Lyme disease is not prevalent, it is usually up to the patient to insist on receiving the Lyme disease blood test. Use this guide to speak with your doctor about your concerns and discuss what the results may mean for your health.
Ongoing Symptoms Of Lyme Disease
A few people who are diagnosed and treated for Lyme disease continue to have symptoms, like tiredness, aches and loss of energy, that can last for years.
It’s not clear why this happens to some people and not others. This means there’s also no agreed treatment.
Speak to a doctor if your symptoms come back, or do not improve, after treatment with antibiotics.
The doctor may be able to offer you further support if needed, such as:
- referral for a care needs assessment
- telling your employer, school or higher education institution that you require a gradual return to activities
- communicating with children and families’ social care

Late Lyme Disease Symptoms
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.

Where Lyme Disease Occurs
In the United States, Lyme disease typically occurs in the Northeast, Mid-Atlantic, and North Central states. It has also been reported to occur in Northern California. The most prevalent strain causing Lyme Disease in the United States is Borrelia burgdorferi.
If you live or have traveled to a state where Lyme disease is endemic, this increases your risk. Lyme disease is endemic in the following states: California, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, Washington DC, West Virginia, and Wisconsin. For regulatory reasons, Everlywell is not able to offer testing in New Jersey, New York, or Rhode Island.
Lyme Sci: Analysis Shows Standard Lyme Testing Is Highly Inaccurate
Lyme disease is spreading rapidly across the world and is currently the most common tick-borne disease in the United States and Europe. Although the diagnosis of Lyme borreliosis can be based upon clinical symptoms, most doctors will rely on commercially available tests kits.
However, studies show that their sensitivitymeaning how well the tests can identify who actually has Lyme diseasecan range anywhere from 7.4% to 86.2%. While early and accurate diagnosis is the most effective way to avoid more serious illness, the fact is many patients will be improperly diagnosed due to faulty testing.

How Do You Test For Lyme Disease With An At
Hereâs how to check for Lyme disease with the Everlywell test.
To take our at-home Lyme Disease Test, collect a small sample of blood with a simple finger prick. Youâll then send the sample to a lab for analysis , and youâll be able to view your results on our secure, online platform.
Consider taking this Lyme test if:
- You have traveled to areas infested with ticks that can transmit Lyme bacteria , found ticks on your body, and are now experiencing symptoms of Lyme disease.
- If you believe you have been exposed to a tick and are experiencing symptoms , taking this antibody test can help assess for Lyme disease. If you have been tested previously, but are now having new symptoms, this Lyme disease test kit can also help.
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.

When Is The Lyme Disease Blood Test Ordered
When someone has the signs and symptoms of Lyme disease or they live in a region that has deer ticks or black-legged ticks, then this blood test will be ordered. It will also be ordered when these symptoms occur without improvement over the course of 7-14 days by most medical providers.
- A bulls-eye rash that grows from the bite site.
- Fevers, chills, and a persistent headache that does not go away.
- Unusual and persistent fatigue that does not immediately improve.
The IgM and IgG tests are generally ordered first when Lyme disease is suspected. This is because people who have never been exposed to the bacteria that causes the disease will not have any antibodies present. If these tests are positive and followed up by a positive Western Blot test, then the chances are very good that Lyme disease is present. This is especially true if antibody levels continue to rise over time.
If My Dog Tests Positive Does He Need To Be Treated
The decision to treat Lyme disease is somewhat controversial since many infected dogs show no signs of illness. Factors that would support treatment include:
a moderate to high value of QC6 signs of illness compatible with Lyme disease at the time of testing a history of illness compatible with Lyme disease within the past year the presence of abnormal levels of protein in the urine.

How It Is Done
The health professional taking a sample of your blood will:
- Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
- Clean the needle site with alcohol.
- Put the needle into the vein. More than one needle stick may be needed.
- Attach a tube to the needle to fill it with blood.
- Remove the band from your arm when enough blood is collected.
- Put a gauze pad or cotton ball over the needle site as the needle is removed.
- Put pressure on the site and then put on a bandage.
Why It Is Done
A Lyme disease test is done to diagnose Lyme disease in people who have symptoms of Lyme disease. Symptoms may include:
- An expanding red rash with a pale centre. This is sometimes called a “bull’s eye” rash.
- Extreme tiredness.
- Headache and stiff neck.
- Muscle and joint pain.
Symptoms of chronic Lyme disease infection include joint pain, stiffness, and problems with the heart, brain, or nerves.
Testing is most accurate when you have risk factors for Lyme disease or symptoms of the disease.

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.
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
