ANA Rflx Titer and Pattern Negative -- This is a screening for autoimmune diseases (such as Lupus, Scleroderma, Sjogren's, etc.). The result is negative, meaning your son does not have any of the antibodies associated with these autoimmune diseases. Most LLMD's will run this test, just to make sure there isn't an autoimmune connective tissue disorder complicating the picture.
B. henselae IgG Screen Negative
B. henselae IgM Screen Negative
B. henselae IgG Titer Not indicated
B. henselae IgM titer Not indicated
These are Bartonella henselae tests and since the screening test was negative for both IgG and IgM antibodies, then the titers were not done. Negative results on this test do not mean he does not have Bartonella, it just means the test did not show any antibodies for it. There are a number of different strains of Bartonella, B. henselae is only one strain and not everyone with Bartonella has this strain and so thus it is entirely possible to have Bartonella and not test positive on this test.
E. chaffeenis Ab Interp antibody not detected
E. chaffeensis Ab IgG <1:64
E. chaffeensis Ab IgM <1.20
This is a test for Ehrlichia chaffeensis and because they did not detect the presence of any antibodies to this bacteria (co-infection of Lyme), the test results for this are negative. Again, there are numerous strains of Ehrlichia so a negative test result does not rule out this coinfection.
Anaplasma phag Ab IgG <1:64
Anaplasma phag Ab IgM <1:20
Anaplasma phag. is another variant of Ehrlichia (formerly known as Human Granulocytic Ehrlichia, meaning the bacteria lives inside of granulocytes...these are a type of white blood cell, the most numerous of which is the neutrophil). The test results for this one are negative as well, but again, negative test results do not rule out the possibility of this infection due to the different strains that are out there.
Babesia microti IgG <1:16
Babesia microti IgM <1:20
Babesia microti is one strain of many known Babesia strains. Babesia is a parasite similar to Malaria in that it infects the red blood cells. The test is negative for this particular strain of Babesia, but again, because there are many strains, this test result does not rule out a Babesia infection.
tTG IgA Ab < 3
Gliadin Antibody, IgA < 3
These three tests are done to screen for Celiac Disease. Because the tTG (tissue transglutaminase) IgA is negative, it does not mean the person does not have problems tolerating gluten grains, but it does usually indicate that there is not significant intestinal damage from the consumption of those grains. A person can still have significant impacts on their health from gluten despite negative tTG test results, and there is also the possibility of sero-negative Celiac Disease. Also, Gluten Sensitivity and/or Wheat allergy may still be present in the absence of tTG antibodies.
IgA looks like the total IgA count in his blood, which is needed in order to ensure there is not a deficiency of IgA affecting the other two tests' results...low total IgA would give false negative results on the tTG and anti-gliadin IgA tests even in someone who has severe Celiac Disease. Since there is not a range listed, I don't know what the lab consideres "normal" for this test result...
Gliadin antibody, IgA - this is a test looking for the presence of IgA antibodies to the gliadin (part of the gluten proteins) found in wheat, rye, and barley - i.e., the "gluten grains." This test result is negative for these antibodies, however a person can still have trouble tolerating gliadin/gluten grains if they have a negative test result on this specific test for several possible reasons: 1) sero-negative Celiac (or IgA deficiency, causing artifically low results & thus a false negative on this test), 2) non-Celiac Gluten Sensitivity - need to check anti-Gliadin IgG to look for this, but again it can be sero-negative, or 3) the person has a wheat or gluten allergy, which is mediated by IgE antibodies instead of IgA antibodies...thus an IgE RAST for wheat (should also include rye & barley RAST tests) would need to be done to rule this in/out...
Also, some find they just do better when they do not eat gluten grains, in spite of negative test results...and also it is known that Lyme Disease can cause or trigger problems tolerating gluten that may or may not show up on the tests.
I do not understand the CD-57 results, so am not able to comment on those. I would recommend, however, that you bring these results to an LLMD and ask them to help you understand what they are showing.
