Is 385 a high rheumatoid factor?

A rheumatoid factor (RF) level of 385 is considered high, as normal ranges typically fall below 15-20 IU/mL, depending on the laboratory. Elevated RF levels can be associated with rheumatoid Arthritis and other autoimmune conditions, but it's important to interpret the results in conjunction with clinical symptoms and other diagnostic tests. Always consult a healthcare professional for a comprehensive evaluation.
