ACLY and autoimmune polyendocrinopathy: The laboratory diagnosis of APS requires at least one of the three following conventional antiphospholipid antibody (aPL) assays tested positive: lupus anticoagulant (LA), anti‐cardiolipin (aCL) antibody, and anti‐β2 glycoprotein I (aβ2‐GPI).8 These three aPLs are by far the most widely accepted tests for APS diagnosis.2 Recently, more and more studies focused on the role of non‐conventional aPLs in RPL patients.
