And here it is – a simple set of diagnostic rules to help you rule out gout in those tricky swollen joints. This study out of The Archives shows us the essential seven factors to know:
- Male sex
- Previous arthritis attack
- Onset within one day
- Joint redness
- Involvement of the first metatarsophalangeal joint
- Hypertension (or one or more cardiovascular diseases)
- Serum uric acid level > 5.88mg/dL
If the score was 4 or less, it pretty much ruled gout out entirely. It becomes harder when the score was in the midrange – between 4 and 8 – and the authors suggest doing a good old fashioned joint aspirate was the way to go.
Keep this rule in mind when you’re seeing your next suspected gout – read all about it here.
