I got a full body checkup and need an opinion on the rheumatoid factor normal range value. My report mentioned: Rheumatoid Factor Quantitative less than 20.0 IU/mL, less than 30 Normal, 30 to 50 Weakly positive, greater than 50 Reactive. Is this normal? Some sites say that up to 14 IU/mL is normal and more than 14 is high. Please advise.

Your report shows Rheumatoid Factor (RF) less than 20 IU/mL, and the lab reference range says less than 30 is normal, so your result is within normal limits. Different labs may use different cut-off values (e.g., 14 vs. 30), which is why ranges vary across websites. A normal RF doesnt rule out joint issues, so if symptoms persist, follow up with anti CCP test and clinical evaluation.
Dr. Rohinipriyanka Suggests...
Take a Anti CCP Test (Cyclic Citrullinated Peptide) Test or Take a ESR Test (Erythrocyte Sedimentation Rate) Test

View allI am 18 years old. Suddenly, my leg got swollen, and my joints started hurting. Now my wrists and shoulders also ache, especially in the morning. I consulted a doctor and did blood tests, but everything came back normal. Why am I experiencing joint pain, and what should I do?

Hi. My mother has been suffering from Rheumatoid Arthritis. We have been visiting a nearby doctor every month, but the condition seems to be the same. We are taking ESR and CRP tests in her blood report every month. According to the doctor, this will take time to improve, but it has been almost eight months, and we have not seen any improvement. Kindly help or suggest on this? Thanks in advance.

I am having pain in both knee joints, so I got my blood tests done for CRP, CPK, Aldolase, and ESR. The results are: ESR is 43, CPK is 80 U/L, Aldolase is 4.40 U/L, CRP is 14.80 mg/L. What do these results indicate about my knee pain?
