Blood results?

Please could someone tell me what RF 192k means and what the range is supposed to be?

There isn't a specific range for the rheumatoid factor (RF). It's basically an antibody, and anything under about 20 is considered negative. Above that it's positive, and just makes it more likely that you have RA.
