Can Lyme Disease Influence C Reactive Protein Blood Test
No: These two disease are caused by very different micro-organisms. Both can be treated, but with different medications. ...Read more
A condition caused by borrelia burgdorferi. Acute symptoms can include bullseye rash, headaches, joint pain, fever, and flu-like sx. Chronic symptoms can include fibromyalgia symptoms, nerve pain in extremities, mood swings, brain fog, heart problems. Lab diagnoses are not very reliable, and sometimes clinical ...Read more
No: Others may argue this point but I firmly believe a positive lyme screen and western blot is essential for the diagnosis. ...Read more
I recently had a blood test, it showed a potential false pos of hep b, but is there a link between Lyme disease and hepatitis?
NO: Lyme does not cause hepatitis. The clinical presentation of the 2 with aches, pains, fatigue, stiffness, weakness can overlap and be confusing. Lyme needs antibiotics hepatitis does not. See your doctor. ...Read more
I had a blood test (Western Blot), to check for Lyme Disease. The results look strange (0.45). This doesn't look like the result of any WB test I have?
Probably not Lyme: Your Western Blot would need to be above 5 for a conclusive confirmation of Lyme disease. Unless you also had known tick bite, low-grade fever, "erythema migrants", you probably had a viral illness that should resolve on its own. Do discuss this with your primary medical provider or specialist if symptoms persist. ...Read more
A month: It takes up to a month for the test to be positive. ...Read more
It is a good test..: Enzyme-linked immunassay is a sreening test which if positive will be confirmed with a western-blot (=standard of testing). Although not absolutely 100%, a negative western blot is a good bet that there is no lyme at the time of testing. Early disease/infection may have negative test, thus recommended retesting in about 3 wks. Lyme dna testing is better, but more expensive. Consult doc. Good luck. ...Read more
What is the best Lyme disease test? I've had the basic blood test done, came back negative, but is there a more thorough test to rule it out?
Thorough WesternBlot: The screen many doctors use, the elisa, only detects about half of those with lyme. A much more sensitive and specific test is the western blot, but I strongly advise doing this through ignenex in palo alto, a specialty lab, as the test offered by most other labs does not include tests for antibodies to the 31 & 34 kda antigens, which are the most specific antigens for lyme! Please see my comment. ...Read more
How accurate is a blood test for Lyme antibodies in diagnosing whether a patient actually has Lyme disease?
What to ask: In general, accredited labs must validate the performance characteristics for tests they offer. That can be hard for a dx like Lyme where there are few definite criteria and many vague symptoms. Antibody testing is very sensitive, but antibodies themselves cross-react. The most sensitive and specific tests aim to detect DNA specific to the organism. Ask the lab for the performance profile of test. ...Read more
I have a bullseye rash around a tick bite but do not have any other symptoms of Lyme disease. Do I need to get a blood test?
Not just Lyme: Avoid being "lyme-centric"! depending on geography, there are several other tick borne diseases (e.g. Anaplasmosis, babesia, human monocytic or granulocytic erlichiosis) that co-infects with lyme (caused by b. Burgdorferi), or else, the diagnosis is something other than lyme (eg. Relapsing fever caused by b. Hermsii & southern tick -associated rash illness [stari] caused by a diffferent tick. ...Read more
Still waiting for Lyme disease blood test results. If it is positive will I need antibiotics from an IV since I am having neurological symptoms?
Can blood test be false negative for Lyme disease? Bulls eye bite on 8/16/13 but symptoms much worse since anesthesia from g.B. Removal on 10/11/13
YES!!!: A bulls-eye rash is pathognomonic of lyme, meaning it alone generally proves you got it. Blood tests are notoriously unreliable for lyme-only half with lyme have a positive eia & the confirmatory western blot has many false negatives, esp. If not done by igenex, the only lab with a reliable test! Ultimately lyme disease is a clinical diagnosis. Treatment requires a comprehensive approach. See comment. ...Read more
Lyme disease ab plus reflex to igg, igm-wb blood test done today. How long for results and how accurate are they?
About a week: The regular lyme test is specific but not very sensitive. There can be many reasons for a false positive result. If it is positive on the screening test it is then sent for the more sensitive western blot test. If the igm test is positive it could represent a recent exposure to lyme disease if the igg is positive it indicates a more distant orast exposure. If the igm is positive you should be eval. ...Read more
Can blood test be false negative for Lyme disease? Had bulls eye bite around 8/16/13 but symptoms much worse after surgery (had anesthesia) on 10/11/3
5 days sore throat, severe body/joint ache & fever (100-102). Thought it was strep or virus, but today I find a bullseye-like bite on my trunk. Can it be Lyme disease? Is it too early for blood test?
Epidemiology: When early lyme is suspected, the diagnosis is based on clinical grounds. Taking a picture of the rash & having a doctor examine it before it disappear is advisable. Other things can cause a bulls eye rash such as a fixed drug eruption, southern tick-associated rash illness, etc. Early recognition is very important. Its too early for an antibody blood test. Epidemiology will help your doc answer. ...Read more
For physical exam blood tests, Do doctors usually check for Lyme disease or does it get noticed in the blood? Does that have to be requested?
ELISA/West blot.: The 2 main tests are elisa and western blot. Elisa or serology is used for screening to see if there is an antibody response to the b. Burgdorferi spirochete responsible for the disease, while the western blot is a specific test that makes sure the positive response is to this and not a false positive, or a reaction to something else. Pcr, or polymerase chain reaction is another possible test. ...Read more

How long do antibodies remain detectable in the blood? I had a clear ELISA for Lyme disease after recurring lightheadedness and brain fog after a possible bite when hiking in the uk but the test was a good 10 months later -would it still be reliable?
Last for years and some others (such as chicken pox) last a lifetime.....It is VERY unlikely that you had a Lyme exposure if the tests are negative in 10 months!
Hope this is helpful

Can a c reactive protein blood test detect peyronies inflamation? If not, how come? What sort of diseases can it find?
No: The CRP is almost always normal in that disorder. ...Read more
Yes: There is every reason to believe that lyme disease can be transmitted via blood transfusion. This does not mean that someone with lyme will always transmit it; in patients with lyme PCR tests are often negative, meaning it is not always present in the blood, but it is at times and in that case is almost certain to be transmitted. Certainly some with lyme don't know it & donate blood & transmit it. ...Read more
What does it mean if your body develops antibodies to Lyme disease And blood work shows my body fighting infection??
No: Routine blood work should not include testing for Lyme disease. The test is only to be run if there is suspicion that the individual has been infected and has the disease. Cholesterol and blood sugar are good screening tests. Tests for rheumatoid arthritis, lupus, Lyme disease are NOT screening tests as there are many false positives. ...Read more
What do you suggest if my doctor ordered a routine lab req for blood work. Will it detect Lyme disease?
No: We don't look for the routinely. Actually, there's some dispute as to just how sensitive the usual Lyme serologies are. If you're concerned that you may be a Lyme patient, talk about this with your physician. ...Read more
What herxheimer reactions can occur when treating chronic Lyme disease? My blood feels poisoned...Rage, dysesthesias, and fatigue are way worse...
When spirochetes: Killed, they release what is called exotoxins. Those toxins are extremely powerful vasodilators as result people develop low blood pressure, high heart rate and other symptoms systemic manifestations. I have seen the worst jerish hexhimers's reaction with louse born relapsing fever treated with penicillin. People die from such reaction than the disease itself (i mean relapsing fever). ...Read more
Does lyme disease and Co infections increase the risk of blood clots? And if so by how much? I take 3000 mg fishoil a day would that prevent issues?
Definitely not: Lyme disease and other tick borne illnesses should not increase the risk for blood clots. See a hematologist if you suffer from clots. There are things that CAN be done - like no smoking, avoiding birth control pills (estrogens), avoiding long stationary periods (sitting on a plane), avoiding injury to legs/veins, etc. Fish oil is a supplement - probably won't help this situation at all. See an MD ...Read more
Hi, I smoke weed every day and I'm also on doxycycline hyclate for early stage Lyme disease, I'm finding Bright red blood diarrhea now?
Blood: Usually bright red blood results from hemorrhoidal bleeding and is less concerning than a darker, purplish jelly like blood which stems from higher up. See a doctor today. Check a CBC to evaluate for anemia. Have an exam to see if you have bleeding hemorrhoids. Stop any blood thinners like aspiring. Please get help. ...Read more
Sign of inflammation:
C-reactive protein reacts with a carbohydrate in the capsule of pneumococci. It is a marker of inflammation. There are two type of CRP tests, conventional, expressed in mg% or mg/dl, and high sensitivity test hscrp expressed as mg/l. The latter is used as one of the risk factors for heart disease.
