Just had test results from bloods. No follow up needed but don’t understand what the results show. Can anyone decipher them?
Rheumatoid factor level

RF can be negative in RA and positive in other;
conditions. Weak positive
RF results have a low;
predictive value except
where there is strong
clinical; evidence of RA.
