Hey all,

I know you are not sure what anything could be with out medical professionals looking at it. I am wondering if you have any ideas for this? I have Lyme disease and one of my Lupus tests came back positive. How can one of the tests be positive and the rest negative?

C-Reactive Protein <0.40 <1.0 mg/dL
Antinuclear Ab (ANA), Screen Neg
Reference range: NEGATIVE

Anti-Smith (Sm) Ab 1
Reference range: <30
Unit: AU/mL

Sm/RNP <1
Reference range: <30
Unit: AU/mL

Double Stranded DNA Antibody 2
Reference range: <30
Unit: IU/mL
< 30 IU/mL Negative
30-40 IU/mL Equivocal
> 40 IU/mL Positive

Histone Antibody 0.8
Reference range: <1.0
Unit: U

Reference Range
Negative <1.0 units
Weak Positive 1.0 - 1.5 units
Moderate positive 1.6 - 2.5 units
Strong positive >2.5 units

ssDNA IgG Antibody 89
Reference range: <230
Unit: U/mL
Reference range:
<69 U/mL Negative
69-229 U/mL Moderate Positive
>229 U/mL Positive
Autoantibodies to ssDNA recognize the purine and
pyrimidine bases of DNA. These antibodies are
found in SLE and may be present in patients with
"ANA-negative" SLE. However, high titers are not
specific for SLE or for risk of lupus nephritis
and may be found in drug-induced lupus, rheumatoid
arthritis, and chronic active hepatitis.

Lupus is diagnosed by having 4 of 11 symptoms (follow link in my signature), but not by a single blood test. Many of the Lime & Lupus symptoms overlap.

Check that out and maybe things will make more sense. Welcome back if you have follow up questions for us!

Okay I know there was some correlation with Lupus if a patient had Lyme and Scoliosis. Which I have both.
