Lyme disease, or Lyme borreliosis, in North America is a group of systemic infections which
may be caused by Borrelia burgdorferi sensu lato (including B. mayonii) [2], B. miyamotoi [3-5],
and other unnamed tick-borne borrelia strains [3, 6]. Currently the diagnosis of emerging or reemerging
infectious diseases largely depends on finding evidence of the causative agents,
including borrelia, in the host by nucleic acid-based tests [7]. The accuracy of any diagnostic
tests must be measured against this standard of microbiological diagnosis. Using a serologic
test kit developed for the detection of antibodies against the epitopes of B. burgdorferi sensu
stricto strain B31 will fail to diagnose most Lyme borreliosis patients in the first two weeks of
acute infection and probably all clinical Lyme borreliosis cases caused by a strain of borrelia
other than B. burgdorferi sensu stricto B31 at any stages of the disease. The inherent inaccuracy
of serologic tests for Lyme disease can be compared with that of the Widal test for the
diagnosis of typhoid or paratyphoid fever (Salmonella infections). A comment extracted from a
Centers for Disease Control and Prevention (CDC) document is copied as follows [8].
“The Widal test is unreliable but is widely used in developing countries because of its low cost. It
is a serologic assay for IgM and IgG to the O and H antigens of Salmonella Typhi, but is not
specific and false positives may occur. Acute- and convalescent-phase titers are more sensitive
than a single serum sample. Newer serologic assays for Salmonella Typhi infection are
occasionally used in outbreak situations, and are somewhat more sensitive and specific than the
Widal test, but are not an adequate substitute for blood, stool, or bone marrow culture.”

My earlier post https://lookingatlyme.blogspot.co.uk/2017/01/over-reliance-on-lyme-disease-tests.html also refers to this, which was discussed by Mary Beth Pfeiffer investigative journalist in a Huffington post article http://www.huffingtonpost.com/entry/flunk-the-lyme-test-just-wait-and-get-sicker_us_5873ef2fe4b08052400ee537?

Dr Lee finishes his comments by saying :-
To overcome the low sensitivity of LD diagnostic tests in patients with early LD at the
spirochetemic stage, we must first acknowledge a need to develop direct detection tests for
Borrelia burgdorferi and related borrelia species known to cause Lyme borreliosis in North
America. To survey the existent useful direct detection tests which may not have been
published due to global editorial censorship by the mainstream medical journals, it is
recommended that blind-coded simulated blood samples spiked with various species of known
borreliae or blank be distributed by government regulatory agencies to all clinical laboratories
performing Lyme disease testing for a bacteriology proficiency survey, as routinely conducted
by the College of American Pathologists for Neisseria gonorrhoeae. The laboratories which
return the correct answers would be invited to further develop a generally accepted diagnostic
protocol to be used by hospital laboratories located in Lyme disease-endemic areas. To be of
use for timely patient care, the results must be generated within 5 working days, preferably in 48 hours. I believe this technology is already available. The first step to the Lyme disease
solution is to cut out the tribalism among the scientists whose careers were built on Lyme
disease research.
