 רעלת הריון מתחת לשבוע 34 – בד"כ קורה אחרי שבוע 34, אם קורה לפני לבדוק APLA.
 3 הפלות חוזרות מתחת לשבוע 10
 אי ספיקה של השיליה לפני שבוע 34.
 בכל מקרה צריך לשלול סיבה אחרת לבעיות בהיריון.
 אם זו טרומבוזה צריך לשלול סיבה אחרת - גנטי בצעירים ובמבוגרים מחפשים יתר לחץ דם, מחפשים גורם אחר לאירוע טרומבוטי - בנשים מעל גיל 65 וגברים 55.
• מעבדתי (צריך 1): Anti cardiolipin IgG, Anti cardiolipin IgM, Lupus anti coagulant, Anti B2 GP1- הנוגדנים מאוד הטרוגנים ושונה מחולה לחולה. צריך תוצאה חיובית לפחות פעמיים בהפרש של 12 שבועות, וטיטר גבוה מעל 40. יכול להיות חולף בגלל דלקת או תרופות.
