Referral to specialist
- Rheumatologist referral is relevant if rheumatic symptoms are present or for "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
