Antinuclear antibody is positive in 1 out of every 9 females.
ANA is reported in tiers that are reported in numbers that double (1:40, 1:80, 1:160, 1:320,...etc).

The higher the ANA titer, the more antibodies in the serum, and the more likely the patient has an autoimmune disease.

However, antinuclear antibodies (ANA) do NOT correlate with disease activity or symptoms severity.

This is my 6th video in a series of lectures about Rheumatology...All of them are in a playlist named “Rheumatology”.    • Rheumatology  

Taking a detailed medical history from a Rheumatology patient is critical because rheumatological diseases can affect any body system (extra-articular manifestation).

In this video, we will talk about quick hints on Osteoarthritis, Rheumatoid Arthritis, Systemic lupus erythromatosis (SLE), scleroderma, sjögren syndrome, and others.

Books that I used:

► Sapira's art and science of bedside diagnosis amzn.to/2DAQk8O

► Hutchison's clinical methods amzn.to/2WZ0fOI

► Guyton and Hall Medical Physiology Textbook goo.gl/yZoeS9
► Goljan Rapid Review Pathology, amzn.to/2MufTPw
► Harrison’s Internal Medicine amzn.to/2OJiVNf
► Goldman-Cecil Medicine amzn.to/2N0v93u
► Davidson’s Principles and Practice of Medicine amzn.to/2vTmf1p

Don't forget the classic rheumatology triad: joint pain, stiffness, and loss of function.
