آزمایش آنتی‌بادی ضد هسته (ANA):
در افتراق بیماری‌های خودایمنی
آزمایش آنتی‌بادی ضد هسته (ANA) یک آزمایش غربالگری برای بیماری‌های خودایمنی است. این آزمایش به دنبال آنتی‌بادی‌هایی می‌گردد که علیه اجزای هسته سلول‌های بدن تولید می‌شوند. وجود ANA نشان‌دهنده فعالیت خودایمنی در بدن است، اما اختصاصی یک بیماری خاص نیست. اهمیت ANA در زمینه آرتریت روماتوئید بیشتر در کمک به افتراق این بیماری از سایر بیماری‌های خودایمنی، به‌خصوص لوپوس اریتماتوز سیستمیک است. درصد کمی از بیماران مبتلا به آرتریت روماتوئید ممکن است آزمایش ANA مثبت داشته باشند (حدود ۲۰ تا ۳۰ درصد)، اما مثبت بودن قوی و با الگوهای خاص بیشتر مطرح کننده لوپوس یا سایر بیماری‌های بافت همبند است.
بنابراین، مثبت بودن ANA به تنهایی تشخیص آرتریت روماتوئید را تأیید نمی‌کند و منفی بودن آن نیز این بیماری را رد نمی‌کند. این آزمایش معمولاً زمانی درخواست می‌شود که پزشک بر اساس علائم بیمار، به سایر بیماری‌های خودایمنی نیز مشکوک باشد و نیاز به افتراق آن‌ها از آرتریت روماتوئید وجود داشته باشد. تفسیر ANA پیچیده‌تر است و نیاز به در نظر گرفتن الگو و تیتر آن دارد.

زمان در تشخیص آرتریت روماتوئید حیاتی است: تحقیقات نشان داده‌اند که بیشترین آسیب‌های مفصلی غیرقابل برگشت در بیماران آرتریت روماتوئید، اغلب در دو سال اول پس از شروع علائم رخ می‌دهد. تشخیص زودهنگام و شروع درمان مؤثر در محدوده ۳ تا ۶ ماه اول ظهور علائم می‌تواند به‌طور قابل‌توجهی از پیشرفت آسیب‌ها جلوگیری کرده و شانس کنترل بیماری و حفظ عملکرد مفاصل را بسیار افزایش دهد
