Medical examinations

• Clinical investigation findings
  • Signs of SLE or other rheumatic disease?
  • Arthritis, skin, blood (low blood cell count), kidneys (edema, urine test), heart, lungs, ANA and other antibodies
  •  Skin symptoms
    • Livedo reticularis / «Marbling» in the skin?
• Serum Antibodies
  • ANA (possibly subgroups), Cardiolipin antibody, Beta-2 glycoprotein antibody, Lupus anticoagulant (Coagulation laboratory)

• Thrombocytopenia (not often)

Referral to specialist

• Rheumatologist referral is relevant if rheumatic symptoms are present or in case of «secondary antiphospholipid syndrome» related to SLE or (rarer) other rheumatic disease
• Hematologist referral if a primarily APLS is suspected
• Maternity outpatient clinic / gynecologist is contacted if planned or present pregnancy

• Refferal to a specialist is preferably sent to the local rheumatological department. If requested, patients may be referred to: Rheumatology Department, OUS Rikshospitalet, PO Box 4950 Nydalen, 0424 OSLO. The department receives patients from the Health Region South East and from other regions as far as capacity is concerned.
• By primarily APLS, one can consider referral to Department of Blood Diseases, OUS
