You can partially demonstrate that by checking o2 sats on both hands. If two positive blood cultures (the first of which is reported) occur less than 21 days apart, the second positive blood culture is not considered a new dialysis event and therefore, is not reported.
Dialysis nurses draw blood and cultures out of the line all the time, so its completely possible to do so. We just let dialysis handle it as its 'their line, not ours'. If different organisms grow from the subsequent.

This tubing usually has a deadspace of about 2.6 ml. Conversely, a single blood culture may miss intermittently occurring bacteremia and make it difficult to interpret clinical significance of certain organisms. Fever) in the absence of another obvious source of infection.
However, many dialysis centers draw postdialysis blood from this site. Cultures from all sites should be drawn within 15 minutes. Each set of cultures should be drawn from a different draw (e.g., 2 different venipuncture sites or a venipuncture plus line site(s).
