Reference Ranges for tTG IgG and IgA: < 7.0 U/mL Negative 7.0 - 10.0 U/mL Equivocal > 10.0 U/mL Positive Reference Ranges for Gliadin IgG and IgA; B2 Glycoprotein IgA, IgG, and IgM: < 7.0 U/mL Negative 7.0 - 10.0 U/mL Equivocal - Repeat testing in 4-6 weeks > 10.0 U/mL Positive Reference Ranges for Thyroglobulin (TG): <280 IU/mL Negative 280-344 IU/mL Equivocal >344 IU/mL Positive Reference Ranges for TPO: <60 IU/mL Negative 60-100 IU/mL Equivocal >100 IU/mL Positive Reference Ranges for dsDNA Ab: <30 IU/mL Negative 30-75 IU/mL Equivocal >75 IU/mL Positive Reference Range for CCP3 Antibody: <20 Units Negative 20-39 Units Weak Positive 40-59 Units Moderate Positive >59 Units Strong Positive Anti-cyclic citrullinated peptide (anti-CCP), IgG antibodies are present in 69-83 percent of patients with rheumatoid arthritis (RA) and have specificities of 93-95 percent. These autoantibodies may be present in the preclinical phase of disease, are associated with future RA development, and may predict radiographic joint destruction. Patients with weak positive results should be monitored and testing repeated. The Anti-Nuclear Antibody test was performed by the indirect immunofluorescence technique using the Hep-2 substrate slides and the anti-Human IgG conjugate, fluorescein labeled. | |
