I was asked recently what is the correct test for Lyme testing. This is why it is important to seek an LLMD trained by ILADS (International Lyme and Associated Diseases Society) To look at the patient. My reply was:
That depends on the patient, how long they have been infected, How much they have been treated after the tick bite. But in most peoples cases when I have a chance to talk with them, They need a test from I-genex. This is an out of house Lab in California that basically specializes in Lyme and infectious diseases and coinfections related too lyme. There are a couple other labs but this is my favorite at this time. The in house blood labs in most of our top hospitals will not recognize lyme. They can not wrap their head around something that they think can not exist. The Lab company such as Quest or many other labs including the best hospitals I have been to will not make a diagnosis anymore without a positive test from the in house Contracted lab. This does not mean you will get a positive test. It means you should be looked at by a LLMD (Lyme Literate Medical Doctor) who usually has lyme or a very sad case of lyme at home with a family member who has been through the mainstream search for answers and found that Mainstream medicine is slow in getting the issue that lyme is a different bear than regular medicine is equipped for. Lyme is rewriting auto-immune science. As for Testing: Elisa test that most doctor (NON-LLMD's) will use as their first defense is about 35% accurate which makes it useless. Then the western Blot that doctors use for early infection is some what helpful to a point or before a person is treated for anything with antibiotics. But after a certain time even that test is not practical and then you need a western blot test from I-genex that is different from the early stage lyme test and about 99% accurate in my book. I have only heard of one negative test and then that child went on to what is called the CD57 test. The child was then found positive and is doing well with treatment. I could go on but as you can see. You can not wrap yourself around just a positive test all the time. Hope this helps.
