New Study Reveals Limitations in ANA Test Kits for Lupus
The variability in serological testing for antinuclear antibodies (ANA) is under investigation after unexpected findings were reported from clinical trials of new agents to treat systemic lupus erythematosus (SLE). In “Assay Variation in the Detection of Antinuclear Antibodies in the Sera of Patients with Established SLE,” David S. Pisetsky, MD, PhD, and his colleagues demonstrate…
New Assays May Help in the Diagnosis & Management of Antiphospholipid Syndrome
A new study found that measuring the presence of additional antibodies specific for Domain I (aDI) of β2-glycoprotein (β2GPI) may improve the diagnosis of antiphospholipid syndrome. Based on their findings, researchers conclude that aDI tests may be a useful addition to, but not a replacement for, standard aβ2GPI tests…
