Can I use the BASDAI score to adjust my medication on my own?

No, the tool is for educational use only. Any changes to treatment should be discussed with your rheumatologist, who can interpret the score alongside your overall clinical picture.

Do I need a blood test to get an ASDAS score?

Yes, the ASDAS calculation includes C-reactive protein (CRP) as one of its components. If you have recent lab results, enter the value; otherwise, the tool will compute only the BASDAI score.

What do the color bands on the results mean?

The color-coded bands correspond to standard disease activity categories (e.g., remission, low, moderate, high) for both BASDAI and ASDAS, helping you quickly see where your score falls on the activity spectrum.

Is my data stored or shared when I use this calculator?

The tool runs locally in your browser; no personal information is required, and the site does not indicate that results are transmitted or retained.

About this tool

What BASDAI Score Calculator does

The BASDAI & ASDAS Calculator on RheumCalc is an interactive tool that walks users through the standard six Bath Ankylosing Spondylitis Disease Activity Index questions about fatigue, neck/back/hip pain, joint pain/swelling, tender area discomfort, morning stiffness intensity, and morning stiffness duration over the prior seven days. It then computes the BASDAI score using the standard formula and, uniquely on this site, also calculates the ASDAS (Ankylosing Spondylitis Disease Activity Score) by incorporating C-reactive protein levels and a spinal pain rating. The result page displays both scores with text labels and color-coded bands, offering a two-in-one assessment of current disease activity. The tool is framed for educational use only, and all inputs are collected on a single page without requiring a paid subscription.

Step by step

How to use the RheumCalc BASDAI Score Calculator

1
Select a number from 0 to 10 for each of the six BASDAI symptom questions based on your experience in the last 7 days
2
Enter your spinal pain score from the past week on the same scale
3
Provide your C-reactive protein (CRP) level if known, or leave blank if unavailable
4
Click Reset to clear all fields and start over, or view the computed BASDAI and ASDAS scores with text descriptions and color bands

Is it right for you

Best for

Patients with ankylosing spondylitis or related conditions who want a quick, free way to generate both BASDAI and ASDAS scores at home and discuss the results with their rheumatologist.

Limitations

Intended for educational use only, not a substitute for clinical diagnosis or treatment decisions
Requires user-entered numerical values; accuracy depends on honest self-reporting
No unit conversion or reference ranges provided within the tool; CRP values must be interpreted by a clinician
